摘要
国土空间生态修复是一项综合性工程,对实现生态平衡和可持续发展有重要作用.本文以肥城市为研究区,采用空间主成分分析法,选取 7 项指标对生态安全状况进行评估,并建立以最小累积阻力模型为基础的生态阻力面,采用距离分析与水文分析相结合的方法,对关键生态廊道进行提取,对关键生态节点进行识别,从而构建区域生态安全格局.
Abstract
The ecological restoration of national land space is a comprehensive project that plays an important role in achieving ecological balance and sustainable development.Taking Feicheng city as the research area,this paper adopts spatial principal component analysis method,selects 7 indicators to evaluate the ecological security status,and establishes an ecological resistance surface based on the minimum cumulative resistance model,and adopts a combination of distance analysis and hydrological analysis to extract key ecological corridors,identify key ecological nodes,and construct a regional ecological security pattern.
