摘要
资源环境承载力评价是一系列国土空间规划的基础,是空间管控底线的重要组成部分。以北京大兴区采育镇作为案例区进行村镇尺度承载力评价探索,建立基于“驱动力-压力-状态-影响-响应”即DPSIR模型的承载力综合指标体系,分析镇内资源环境状况,得到各村承载力评价分级结果和基于承载力提升的空间规划方案评估结果。结果表明,采育镇内各村资源环境状态存在较大差异,这主要是由于各村人口密度、用地集约程度差异导致,也与各村用地结构、经济发展模式直接相关。该研究对未来小尺度承载力评价思路提出展望,同时为其他地区小尺度资源环境承载力评价提供参考。
The evaluation of resources and environment carrying capacity is the basis of spatial planning and a key part of spatial governance.The existing research on capacity calculation focuses on large spatial units such as provinces,cities and counties,and the evaluation of carrying capacity at small-scale is relatively scarce,which cannot meet the needs of environmental management of villages and townships.In this study,Caiyu Township in Daxing District of Beijing is taken as a case to evaluate the carrying capacity of villages and townships.A comprehensive index system of carrying capacity based on DPSIR model is established to analyze the resources and environment conditions in Caiyu Township.The grading results of carrying capacity evaluation of each village of Caiyu Township and the evaluation of space planning scheme based on the enhancement of carrying capacity are presented,and the results show that there are great differences in resources and environment status among villages in Caiyu Township due to the variety of population density and land use intensity related to the land use structure and economic development mode of the villages.This paper concludes with the future research of carrying capacity evaluation at small-scale,which can provide reference for other regions.
