“空间冲突-功能障碍”视角下国土综合整治内涵、机制与实证.

Integrated territory consolidation has been used to alleviate the contradiction between resources and environment in the new era. It is a high demand to define the connotation and then determine the work tasks for the land rectification. In this research, a theoretical system of integrated territory consolidation was proposed for the “problem-approach-goal”, together with the comprehensive remediation program of “elements transformation, boundary control, and global remediation” under the guidance of “point-line-plane” all-round remediation using the analytical perspective of land “spatial conflict-functional obstacles”. An implementation mechanism of integrated territory consolidation was constructed for the explicit contradictions and hidden obstacles, particularly for the requirements. After that, the relevant policies and standards were selected to identify the conflicts in the territorial space, including five conflict manifestations: ecological protection, basic farmland, construction land management, reserve cultivated land resources, as well as abandoned industrial and mining land. An evaluation system of land functions was established in terms of the “production-living-ecological” function and the connotation. The land functional obstacles were identified, according to the obstacle degree model. The conflicts and obstacles were regarded as the focus of short-term and long-term remediation tasks, respectively. A “partitions + type” model of integrated territory consolidation was formulated with the naming principle of “significant conflict + first obstacle”. A case study was carried out in Sichuan Province, China. The empirical analysis greatly contributed to solving the real contradictions and short boards for the land potential and the theoretical mechanism. The results were as follows. 1) There were significant spatial differences in the land conflicts in the study area. The areas with intense conflicts were mainly distributed in the eastern and southern parts of the province. 2) The “production-living-ecological” functional level distribution presented spatial agglomeration characteristics. The production function exhibited a distribution trend of “high in the middle-low in the east and west”. The living function showed a significant distribution of the east high and west low. The high-level areas were mainly distributed in the eastern plains and hilly areas. The ecological function was generally presented in the low distribution of the east or high west, whereas, the high levels were mainly located in the mountains around the Sichuan Basin. The most significant obstacle factors that hinder the “production-living-ecological” function in the province were cultivated land layout, living security, and ecological security. 3) According to the land-space conflict identification and functional impairment evaluation, Sichuan Province can be divided into four partitions of remediation areas: key remediation, urgent tidy, prior digging and moderate optimization areas, with the eight types including “layout optimization-facilities improvement-ecological protection”. 16 integrated territory consolidation modes can be obtained for the coupling types and partitions, corresponding to the short-term, long-term remediation strategies. Each county can take the remediation measures, according to local conditions and zoning classification. The research can be conducive to the theoretical research and practical cognition of integrated territory consolidation. The finding can also provide a strong reference for the consolidation and planning at the provincial (city) scale. [ABSTRACT FROM AUTHOR]
