摘要
构建生态安全格局可为国土空间规划提供全域生态问题分析和解决对策,弥补现有国土空间生态规划的不足.以朝阳市为例,在国土空间规划的大背景下,基于景观联通性理论、最小累计阻力模型及电路理论等相关理论模型提取生态源地、生态阻力面、生态廊道和生态夹点,构建了朝阳市"一轴两带、东西两屏、五心多点"总体生态安全格局.通过对朝阳市生态安全格局的构建,体现了山水林田湖草生命共同体思想,突出了不同生态要素之间的联系,为同类城市的国土空间规划提供了支撑.
Abstract
Constructing an ecological security pattern can provide a comprehensive analysis of ecological issues and solutions for territorial spatial planning,addressing the shortcomings of the existing ecological planning of territorial space.Taking Chaoyang City as an example,within the context of territorial spatial planning,this study extracts ecological source areas,ecological resistance surfaces,ecological corridors,and ecological nodal points based on landscape connectivity theory,the least resistance model,and circuit theory.The overall ecological security pattern of"one axis,two belts,east-west screens,and multiple points at the center"for Chaoyang City is established.Through the construction of the ecological security pattern,the concept of an ecological community of mountains,waters,forests,farmlands,lakes,and grasslands is embodied,emphasizing the connections between different ecological elements,providing support for the territorial spatial planning of similar cities.
