With the trend of green development of natural gas industry, the quality of natural gas products is upgrading rapidly. Thus the level of analysis technology of total sulfur content as a key indicator needs to be improved to meet the production demand of online monitoring. Based on the extensive investigation and analysis of the development trend of natural gas industry and technical indicator s, this paper introduces the international standardization research results of total sulfur detection technology, and carries out the experimental research on the detection limit, repeatability and consistency of three on-line detect ion methods of total sulfur (GC-μTCD, GC-IMS, GC-FPD). The results show that the three methods are applicable to detect total sulfur in natural gas, which provides the foundation for the selection and optimiziltion of the on-line analysis method of total sulfur in the future. Finally, it is pointed out that the realization of online detection of total sulfur in natural gas is the trend of future development. Tn the next step, we will continue to c<1rry out on line total sulfur detection by chromatography technology and take part in the international standardization, in order to further establish China's leading position in this field, and provide technical support and standardation guarantee for the green development of natural gas.

Noise pollution has become the second major environmental issue after the air pollution. It negatively affects public health,animal and plant growth,that therefore seriously hinders the sustainable development of ecological environment. To obtain detailed noise distribution information,several countries have launched the noise mapping strategic action. This paper first summarizes the development roadmap of environmental noise sensing technologies in China,and discusses its current state. Then,a comprehensive survey of recent developments on acoustic sensor networks is provided in terms of system architecture,low-cost sensor node design,sound taxonomy and classification,as well as energy harvesting and mobile sound sensing. Based on that analysis,four open issues regarding energy-efficient sensing,lightweight sound noise identification,dependable wireless multimedia transmission and node deployment are identified. Finally,some insights for future research directions are presented. [ABSTRACT FROM AUTHOR]

Sustainable development has been a hot topic in the international community for some years. Sustainable investment in tourism now plays an important role in economic growth; increasing employment and helping in the adjustment of the economic structure in the host country. Although government expenditure is a key factor, it cannot always meet the financial needs of the host country. Foreign direct investment (FDI) is an important complementary source of finance for a developing economy. In China, the use of FDI in tourism is just beginning, and it is a very complex process, which involves a variety of stakeholders. This article describes the relationship between FDI and the sustainable development of the tourism industry. Detailed analyses were carried out with three perspectives in mind: (1) From the perspective of economic development - sustained growth of investment can bring a host country important direct economic effects such as income growth, higher employment and foreign exchange levels, while some benefits may also be gained from the transfer of technology and management practices; (2) From the perspective of social culture - the sustainable development of investment is not just an economic activity, but also has strong cultural attributes, and can also contribute to regional image promotion; and (3) From the perspective of the environment - sustainable investment can have positive effects on the environment, such as enhancing environmental standards. There are many factors that might affect the absorption of foreign direct investment in Chinese tourism. The number of tourist arrivals can affect investment in the hotel industry. Sustainable investment needs a long gestation period, the a stable policy environment is necessary. The ability of the investment management department in the host country also plays an important role in negotiating with investors, and in the effective development and implementation of sustainable investment rules. However, any increase of tourist arrivals due to investment in tourism requires more infrastructure, and this will increase the cost of investment. Investors also need reliable, comparable investment data, and a choice of other investment opportunities to finalize their plans for investment. In addition, effective tourism investment requires the development of a high quality labor force, because the service quality of the labor intensive industry depends on the quality of employees. In this paper, an absorption strategy for FDI in tourism is proposed. Incentive policies with the aim of promoting sustainable development investment and sustainable development goals for enterprise are all encouraged. The expansion of service objectives and the absorption of professional knowledge will promote sustainable development as a standard targeted system. This will benefit the shaping of the image of regional tourism through market research, marketing, and the selection of investment promotion techniques. A helpful and powerful relationship between the host and investment countries can thus be built by establishing various forms of partnership, such as international institutions, multinational corporations and travel organizations. Last, but not least, it is necessary to establish an index system and a reporting system for the evaluation and supervision of sustainable tourism investment. [ABSTRACT FROM AUTHOR]

The natural gas from the eastern line of China and Russia will soon be introduced into China, it will play a strong role in promoting the natural gas utilization projects in the northeastern area and also face various problems. In order to establish a long-term sustainable development resource supply system, combined with the actual situation of energy supply and demand, the future development direction of natural gas in Northeast China after the arrival of Russian gas is discussed in this paper. The main problems are analyzed as follows: the lack of self production and high dependence of outside the region; many choices of alternative energy by the regional characteristics; peak shaving difficult and the surplus hard to deal with; poor substitution economy and the price too high to bear. Some measures on the contradictions are summed up. Diversification of sources and resources can be ensured to sustainable development. It is clear that natural gas should be used as the transitional energy in Northeast China, and some suggestions on the utilization of natural gas for regional economic development are put forward.

Preventing environmental pollution from the source is an important way to establish a green development mode in China. Promoting the development of organic agriculture is an important way for the green transformation of agricultural production methods and the coordinated development of ecological environment protection. From the perspective of ecological environment protection, this paper first divides the work carried out by China′s environmental protection departments in promoting organic food development and organic product base construction (1994--2019) into three stages according to the level of development, function, and policy situation. Secondly, it summarizes the comprehensive benefits of constructing organic product bases in the prevention and control of nonpoint source pollution, farmland biodiversity conservation, ecological poverty alleviation, and ecological product supply. Finally, countermeasures for the development of organic agriculture and the construction of organic product bases for the development of the ecological economy, prevention and control of nonpoint source pollution, promotion of rural ecological environment supervision, and ecological poverty alleviation are proposed.

The energy endowment characteristics of "relatively rich in coal, poor in oil, less natural gas, and uranium deficiency"in China result in that the coal resources as the China’s main energy will not change in the short term.Meanwhile, the relatively abundant coal resources are still the most stable and cost-effective competitive minerals in China.There should be a clear understanding that it is unrealistic, unwise and unscientific to abandon the actual energy choices based on coal to solve China’s energy problems. However, it should be noted that the coal resources have brought about environmental pollution, ecological damage, waste of resources, and high emissions in the whole process from geological exploration to development and utilization.Therefore, the development of the coal industry in China will certainly undergo some significant changes in the new era.Implementing scientific exploration and development, clean utilization, and low-carbon consumption, characterized by science, safety, ecology, high efficiency, standardization, digitization, and intelligence, is the only way to realize the sustainable development of China’s coal industry.Aimed at the challenges and opportunities for the coal industry in China, the present situation and existing problems of coal resources in the whole process from geological exploration to development and utilization is analyzed, and the strategic thinking of building an upgrade version of main energy( coal) industry in China is proposed.In this paper, the authors focus on 11 key scientific and technological problems faced in the process of realizing the upgrade version of China’s main energy( coal) industry, namely the problems of comprehensive coordination, green exploration, deep exploration, and intelligent exploration for coal resources in the process of geological exploration; the problems of green, safety, recovery rate, occupational health, and high benefit in the coal development process; the clean and low-carbon problems in the process of consumption and utilization.Meanwhile, the corresponding exploratory solutions are put forward.It is of great theoretical significance and practical value to promote the transformation and upgrading for China from a large coal producing country to a powerful coal industrial country, and also to address the sharp contradiction between China’s current economic and social development and the protection of ecological environment.

Water resources destruction and geological environment changes caused by mining in ecologically fragile areas of western China have seriously restricted the sustainable development of economy, society and environment in mining areas. Through reviewing the research progress of water-preserved coal mining and carrying capacity of geological environment in coal mining areas, and combining with the current situation of geological environment in western China rich in coal and short of water, the research framework of carrying capacity of geological environment based on the concept of water-preserved coal mining is proposed. It is considered that the function mechanism of "coal mining activity-water resource destruction-geological environment effect"should be systematically analyzed by combining the concept of water-preserved coal mining with the theory of carrying capacity of geological environment. The methods of attribute analysis, ecological demand analysis, numerical analysis and catastrophe theory should be used in studying the carrying capacity of geological environment. In particular, the quantitative method, comprehensive evaluation method and the classification method of carrying status and carrying capacity of geological environment should be investigated. By means of simulation experiment, the relationship data between the geological environment and the critical value of mining intensity under the carrying capacity of typical coal mine area are obtained. Then the technological method of coal mining under water-containing for controlling and alleviating the geological environment problems in coal mine area is extracted to determine the reasonable mining intensity and scale. On the basis of the research of carrying capacity, this paper put forward the collaborative monitoring method for the influencing factors of carrying capacity of geological environment, and the criterion of bearing capacity early warning grade of carrying capacity. The connotation and basic research ideas of geological environmental carrying capacity based on the concept of water-preserved coal mining will enrich the scientific connotation of water-preserved coal mining and geological environmental carrying capacity, and provide a theoretical and technical support for the coordinated development of coal resources and water resources protection in the fragile ecological environment areas of western China.

Coal mining with water protection is an inevitable choice for the sustainable development of ecologically fragile mining areas. The study and application of coal mining with water protection is an urgent problem to be solved in coal development planning, construction and production in northwest China. Taking Yushen mining area in northern Shaanxi Province as an example, this paper studies the types of water-preserved coal mining coalmines in combination with the quantity distribution of shallow water resources( water-preserved coal mining target seam) and the impact of coal mining on shallow water resources. Firstly, the spatial occurrence structure characteristics of eco-water-coal measures strata in the study area are analyzed. Also, the eco-geological environment types for the purpose of water-preserved coal mining are proposed, which are divided into oasis type with phreatic water and bottomland in desert, oasis type with surface water and valley river, loess gully type with surface runoff, and regional deep groundwater enrichment type. Secondly, the distribution of total storage per unit area of shallow water resources is calculated and determined. Then, based on the influence degree of coal mining on ecological layer and shallow water, four types of environmental engineering geological patterns( basically unaffected model, gradually restored model after destruction, gradually deteriorated model and disaster model) are proposed. Based on the analysis of the key indicators affecting the division of environmental engineering geological patterns, including the height of the water-flowing fractured zone and the mining water-resisting of residual aquiclude, etc., the zoning threshold and determination method for environmental engineering geological patterns is established. Finally, based on the distribution characteristics of shallow water resources and environmental engineering geological patterns, the grade types of water-preserved coal mining coalmines are put forward for the first time, which is divided into normal mining mine, water-preserved coal mining first-class mine, water-preserved coal mining second-class mine and water-preserved coal mining third-class mine.

The Mekong River Commission is the only international intergovernmental organization in the Mekong River basin engaged in water resources development and management, but its institutional system effectiveness has been questioned. Especially the "Procedures for Notification, Prior Consultation and Agreement" concluded in 2003, which was successively applied to the Xayabury, Don Sahong and Pak Beng hydropower stations in Laos, not only failed to reconcile the differences of interest and contradictions of member countries, but also caused great controversy. As the mainstream hydropower development accelerates, the objective environment for China to participate in the development and management of water resources in the sub- regions is also changed. There is an urgent need to strengthen relevant theoretical foundation and practical research to promote basin development cooperation and sustainable development. Therefore, this paper mainly introduces the institutional framework, management mechanism and operating process of the MRC prior consultation mechanism, while objectively analyzes its achievements and problems based on the three practices, and then puts forward suggestions for improvement in four aspects, such as supplementing an explanatory document, making provisions for benefit compensation and public participation, as well as perfecting the process of prior consultation. Finally, we discuss the impact of the MRC prior consultation mechanism on China's participation in the whole basin management and effective countermeasures, which will provide reference and enlightenment for China's water resources development and cooperation policy under the Lancang- Mekong cooperation framework.
