Abstract:

In conderations of the regional differentiation characteristics, dominant ecological functions and typical ecological problems, this article explores the territorial land zoning for ecological restoration in Jiangxi Province to provide scientific and technological supports for the preparation and implementation of ecological restoration plans as well as for the realization of land management and control in Jiangxi Province. Guided by the ideas of life community, harmonious rural development, and suitable management, by delineating the principle and ecological functional spaces, and taking into account both the practical ecological problems associated with rural development and the demands for comprehensive development, we use the multi-factor comprehensive spatial analysis method, combined with the “top-down”, “bottom-up” approach, to achieve the three-level ecological restoration of territorial land. The territorial land zoning divides the plains and lakes in northern Jiangxi and the hills and basins in central, western, southern, and eastern Jiangxi into 5 level-1, 24 level-2, and 70 level-3 ecological restoration zones. Through the three-level zoning, the characteristics of the territorial land are clarified, the leading ecosystem function are specified, and the key areas of ecological restoration are identified. It provides a decision-making basis for the implementation of ecological restoration projects and land governance as well as a scientific and technological approach for the overall protection, systematic restoration, and comprehensive governance of territorial land.

Key words: ecological restoration zone, dominant ecological function, ecological functional zone, Jiangxi Province
