基于GIS的自然生态空间边界划定与分区研究——以肃南裕固族自治县为例
|
摘要
为完善国土空间用途管制,以祁连山地区的肃南裕固族自治县为例,基于ARCGIS平台探索自然生态空间划定与分区方法,形成统一自然资源调查数据,开展国土空间适宜性评价,划定三类空间和优化自然生态空间分区的三类空间划分技术思路;以生态保护红线作为自然生态空间的基础,将自然生态空间划分为生态保护红线和一般生态空间,根据现有法律法规规定的管制要求和各类保护区的功能划分,将生态保护红线区划分为核心保护区、生态修复区和传统利用与游憩区,面积分别为3 947.28、3 216.89、6 936.56km~2;针对自然生态空间划定与分区过程中出现的突出问题,提出了统一底盘、优化生态保护红线、协调统一管理边界等相关建议。
In order to improve the control of land use,taking Sunan Yugur Autonomous County in Qilian Mountains as an example,this paper explores the method of natural ecological space delimitation and zoning based on ArcGIS platform.Three kinds of space division techniques are formed to unify natural resources survey data,carry out land spatial suitability evaluation,delimit three kinds of space and optimize natural ecological space division.According to existing laws in China,based on ecological protection red line,natural ecological space is divided into ecological protection red line and general ecological space. According to the regulation requirements and the functional division of various protected areas,the red line area of ecological protection is divided into core protected area,ecological restoration area,traditional utilization and recreation area with the area of 3 947.28 km~2,3 216.89 km~2 and 6 936.56 km~2,respectively.In view of the outstanding problems in the process of delimitation and regionalization of natural ecological space,some suggestions are put forward,such as unification of chassis,optimization of ecological protection red line,coordination and unification of management boundary.
