Earned Value Management Method (EVM), widely used in the world, is a project management method of costschedule integrated control. But the traditional EVM sometimes cannot provide an accurate result. In this paper, a practical method is given to analyze the project performance, in which the Network Diagram Method and the Critical Path Method have been introduced into EVM system that can better reflect the practical situation of a project. This improved method can be referred to assub-level earned value analysis method. This method can correct variance in the duration and cost forecast of the traditional EVM, and can also provide more information about the cause analysis.

In order to ease environment pressure and alleviate the scarce problem of energy, Chinese government has begun to exploit and develop shale gas (SG) since 2009. However, the formation of competitive market is bristled with difficulties, due to its infancy, imperfect and lack of standardization. This paper firstly analyzes the status quo of technology, policy, cost, and competition of SG industry in China. Then a system dynamics (SD) model is built to show various trends of Chinese SG industry under different scenarios, which shows that technology, policy and cost all have effects on competitiveness. At last, the simulations reveal that the number of competitors in Chinese SG industry will arrive at its peak from 2019 to 2020. The corresponding recommendations have been presented: Chinese government should pay more attention on the perfection of laws and regulations of SG industry. And competitors should focus on increasing R&D investment.

With the increasing of energy demand and environmental pressure, China government has been exploring a way to diversify energy supply. Shale gas development is becoming an important energy strategy in China in recent years due to giant shale gas reserves. However, the shale gas market is preliminarily shaping in China, so that many factors have great influence on its competition. To find these factors and to control them rationally is good for the cultivating Chinese shale gas market. Five forces model for industry analysis puts an insight into the competitive landscape of shale gas market by showing the forces of supplier power, buyer power, threat of substitution, barriers to entry, and degree of rivalry. Illustrating the key factors that affect competitive landscape provides a view into the situation of shale gas industry. The variation tendency of shale gas industry is analyzed by setting various scenarios. Finally some suggestions are proposed in order to keep the development of shale gas industry positively.

Site selection plays an important role in the entire life cycle of solar–wind hybrid power station (SWHPS) project and is worthy to further study. There are problems in the present researches: first, the SWHPS site evaluation results are difficult to be understood by the project managers due to the evaluations of SWHPS site are few from the perspective of project management. Second, the independence of experts is difficult to be protected since the undefined duties of roles in the evaluation process Third, the project managers cannot consider the alternatives thoroughly because that the evaluation result is single. Hence the innovativeness of this paper is as follows: first, the evaluation attributes of SWHPS site selection are summarized from the perspective of project management; second, the duties of roles in the decision process are defined; third, according to the principle of practicality, a decision framework of SWHPS site selection is built based on the analytic hierarchy process method, the merits of this decision framework are that it can provide various rankings of alternatives and is easy to be used. Finally, a case study of China demonstrates the effectiveness of decision framework.

Independent renewable energy power stations based only on wind or solar power system cannot provide continuous electricity. Wind/solar hybrid power systems can offer a possible solution to this problem. However, there is much more influencing factors in the progress of site selection as the site selection of hybrid power systems is much more complex than of independent ones. To resolve this problem, we use literature statistics to determine the index of site selection scientifically. Therefore, the Matter-Element Extension method and its improved version (Ideal Matter-Element Extension method) are applied to evaluate hybrid renewable sites. We chose three regions with abundant wind and solar energy in China as case studies for these models and obtain the weights of the index by Rank Correlation Analysis. The no difference results of the two models and the installed capacity of these places will prove its effectiveness meanwhile the improved Ideal Matter-Element Model can rank order all evaluation objects. So, this paper will provide a theoretical basis to selection of the sites of wind/solar hybrid power stations.

China has been one of the biggest energy consumers in the world, while buildings in China take up over 30% of the total energy consumptions. As conventional energies like coal, oil and gas are drying up, building energy conservation and emission reduction appear to be increasingly crucial for the sustainable development of China. Chinese government has been extensively promoting the development of green building since 2004. Many researches have been carried out in this field but the overall review is insufficient. This paper aims to give a detailed review of green building development in China, and find out the defects and risks. Data of the demonstration projects of renewable energy application in building is collected and analyzed. Related policies and researches are reviewed. It can be concluded that the major defects lie in the policy shortage, technology deficiency, and market immaturity.

Gansu province is relatively less developed in economy, whereas abundant in Renewable Energy Sources (RES). It has been counting on heavy industry for a long time and highly dependent on fossil fuels, causing serious pollutions. Meanwhile, its own power demand is insufficient, thus its RES-generated electricity must be out-delivered. After the Renewable Energy Law (REL) took effect in 2006, RES development is booming in this area, bringing about a series of problems as well. This paper aims to present the current status, future potentials and challenges in Gansu by carrying out a detailed review of relevant studies, along with surveys on the wind and solar developers. Particularly, Gansu is a typical province in terms of RES development in Northwest China. It can be concluded that the RES development in this district is policy-driven to avoid risks in technology cost efficiency, grid co-development and so on.

Analyzing daily air temperature and precipitation observed during 48 years from 1958, we quantified changes in temperature and precipitation with year in Kherlon River Basin of semiarid northern China. In addition, the relationship between the dry biomass measured 23 years from 1983 at a grassland and the corresponding temperature accumulated for higher temperature than 5 °C (AET) and precipitation accumulated after 1 April (CP) was determined. It was estimated that the annual mean air temperatures during non-growing season (October to April) and growing season (May to September) had significantly risen during 50 years from 1958 by 2.38 °C and 1.83 °C, respectively. The year-to-year variation in the annual mean air temperature had a tendency to increase with year during the 48 years. Changes in annual precipitation and precipitation days for any of the entire year (January to December), growing and non-growing seasons with year were not significantly observed. Both the AET and CP (especially CP) during the growing season affected the biomass growth in the semiarid grassland. Prediction of seasonal changes in meteorological tendency as well as that of climate change is important to maintain the production in semiarid grassland and to conserve the plant community and landscape.

Cost control in the wind power construction project is essential under the trend of developing wind power in China. In order to carry out cost control effectively, structural interpretation model(ISM) is used to identify and analyze the major factors that affect the implementation of cost control and the hierarchy relationships between each other. In this way, the surface causes, the middle causes and the underlying causes that affect the cost control in the wind power construction project have been found, which provides decision theory for the smooth implementation of cost control in China's current wind power construction projects.

The Clean Development Mechanism (CDM) is one of important mechanisms to assist in achieving the mitigation target assigned in the Kyoto Protocol. However, the additionality of small-scale hydropower project activities has been a debated issue in the Parties. The method for assessing the additionality is the core for the eligibility. On the basis of Shiba hydropower CDM project, this thesis discusses the types and their essential implications of the additionalities of small-scale hydropower CDM project activities, and the rationality and feasibility of the methods for assessing additionalities, hoping to the contribution to preparation and implementation of small-scale hydropower CDM project activities in China.
