基于生态约束-发展潜力的城镇建设用地开发适宜性分区
Suitability Regionalization for Exploitation of Urban Constructive Land Based on Ecological Constraints and Development Potential
摘要
Abstract
[Objective] To determine the suitability types of urban construction land development from the perspective of ecology and economy,and provide reference for the spatial distribution of land use in Sheyang County of Jiangsu Province.[Methods] According to the minimum cumulative resistance value,the regional ecological constraint intensity of Sheyang County was analyzed and the intensity grade was defined.Through the uses of multiple factors and multi-factor comprehensive discriminant model,an evaluation model was constructed from the perspective of development intensity and spatial distance,and the regional development potential grade was ranked.Finally,on the basis of ecological constraint level and development potential level,the suitability zone of the whole urban construction land development was divided into different types.[Results] (1) The areas with high ecological constraints were largely different from those with low ecological constraints,where ecological protection was the main factor.From the point of view of spatial distribution,different levels of intensity and ecological binding showed a ladder like distribution,from the inside to the outside of the research area,and the intensity gradually leveled up.(2) The comparison results of development potential and ecological constraint classification showed that the contradiction of development potential was prominent.The demand for economy was vigorous,and the situation of ecological protection land was pressing.(3) Suitable protection area,relatively suitable protection area,relatively construction area,suitable construction area,covered 11.04％,24.78％,34.59％,29.59％ of the total research area respectively.[Conclusion] The development suitability zone has an alternative structure and characterized by "urban area as core and rural area as periphery".Meanwhile,suitable construction areas are gathered in and around the Hede Township and gradually reduced on the periphery.关键词
