[Objective] The aims of this study are to construct compound industrial model based on the multifunctional characteristics of land use, and to provide methods and references for improving the land use efficiency and promoting the high-quality development of regional ecology and economy. [Methods] Fuping County in the middle part of Taihang Mountain was taken as an example. 9 types of ecosystem service functions, such as water supply and soil conservation, were selected as the basis to evaluate the spatial agglomeration characteristics of land functions in Fuping County. Through spatial clustering analysis, different functional value clusters were obtained and adjusted to form the dominant functional value zones of ecosystem services. On this basis, land use status, landform and existing industrial development layout, were superimposed to build a complex industrial development mode. [Results](1) The study area was divided into six functional value clusters according to the spatial agglomeration characteristics of ecosystem service value.(2) The boundaries of each cluster was adjusted to form six dominant functional value areas of ecosystem services, including maintaining biodiversity+providing aesthetic landscape+soil conservation area, providing aesthetic landscape+water supply+raw material production area.(3) On the basis of the ecosystem service leading functional value area, seven development modes of complex industries such as ‘tourism+cultural industry’ and ‘smart agriculture+tourism’ are designed, which can provide new driving forces for the rural revitalization and high-quality development of Fuping County. [Conclusion] The design of compound industry model can realize the dual development of ecological protection and economic development, and can provide a case reference for solving the contradiction between ecological protection and economic development in mountainous counties.

In order to quickly and accurately grasp the spatial distribution and effectively promote the security protection of small-scale cultivated land resources, the paper took Changli County, Hebei Province as the research object, used documentary research method to perfect the connotation of cultivated land resource security and constructed evaluation framework suitable for cultivated land resources at county level. Taking the agricultural land classification results in Changli County in 2015 as the data base, and combined with the data of land use survey, agricultural geological survey, and soil sampling and detection information in the same period, the database of cultivated land security was built; and the single index evaluation method was used to evaluate the elements which affected the safety of cultivated land resources. The evaluation results showed that there were nearly 15% of the cultivated land in low yield level, nearly 10% of the cultivated land in bad condition of irrigation, nearly 15% of the cultivated land below the critical safety level of soil profile pattern, and nearly 10% of the cultivated land in low level of available phosphorus. In addition, soil organic content in the whole county was under the safety grade, and the content of copper in the regions with very small area was at low-level insecurity. Fertilizer use quantity in most regions was at low-level insecurity. Aiming at the unsafe danger of cultivated land resources in Changli County and with the uniformity principle in engineering technology and monitoring management measures, the paper overlapped the evaluation results which showed insecurity problems, lined out comprehensive engineering renovation zone, fertility promotion zone and abandoned farmland zone, and put forward the corresponding regulation and monitoring management system. The research showed that using the result of farmland classification can build database of cultivated land security quickly, also can promote the normalization of the monitoring work of cultivated land resources safety and implement safety diagnosis and evaluation regularly. All of these can efficiently implement full elements supervision and protection of cultivated land resources. [ABSTRACT FROM AUTHOR]

Changing the inefficient utilization situation of rural residential areas and carrying out the reconstruction and optimization of their spatial layout, can promote the rational allocation of resource, capital and labor force in the rural areas, and make the rural areas adapt to and be integrated into industrialization and urbanization to promote the coordinated development of urban and rural areas. This paper extracts appraisal units and vector spatial data using the geographic information system (GIS) tools. When constructing the index system of rural residential space reconstruction and evaluation criteria, the paper takes different indicators' combinations into full account, which can produce different effects to the evaluation objectives and the appraisal orientation. And in order to avoid lacking consideration on the complexity of the interaction between each evaluation index in the related studies using the comprehensive index evaluation method, the paper constructs two-step appraisal method by fusing hierarchical evaluation method and comprehensive index evaluation method. The first step is to construct the appaisal indicator system and appaisal criteria under multiple logical conditions for the spatial reconstruction of rural residenial areas, and then to carry out hierarchical appraisal to get the grading results of agricultural industry advantages, consolidation potential, moving and merging conditions, and economic and location conditions of settlements and so on. Combined with appraisal results obtained from the previous step, the second step is to construct the reconstructing discrimination criterion using discriminant evaluation method and carry out the spatial reconstruction zoning of rural residential areas in Changli county. Then, by overlaying livability assessment results on the spatial reconstruction zoning map, and introducing strategic choice evaluation, the paper adjusts and improves Changli county's residential space reconstruction zoning plan. Changli county is divided into agricultural priority area, city priority area, distributary area and minimum living area, and relocation and reconstruction strategy is put forward for each type of rural settlement. At last, the paper combines the social economic situation and urbanization construction objective of Changli county, constructs the development pattern of "county area - primary small towns - secondary small towns - new rural residential communities", and discusses the issues that require attention in the process of migration. The scheme can promote the implementation of "Twelfth Five Year Plan" and "Thirteenth Five Year Plan", help adjust the measures suitable for local conditions, promote the county's new town construction and the process of new-type urbanization construction, and provide new idea for rural modernization, industrialization and urbanization in Changli county.
