摘　　要：开展自然保护区所在地景观生态风险研究对于国家生态安全发展意义重大。以大布苏国家级自然保护区所在地——乾安县为例,利用ArcGIS、Fragstats、SPSS等软件,分析2003年—2023年乾安县土地利用及景观格局变化,揭示景观生态风险演化过程,并讨论乡镇聚落空间密度与景观生态风险的相关性。进一步提出空间格局优化方法,将研究区域划分为修复区、改善区、管控区,进行针对性生态治理,以期为我国自然保护区所在地的景观生态风险研究、治理及规划提供有益借鉴。Conducting the research of landscape ecological risk in the location of nature reserves is of great significance for the development of national ecological security.Taking Qian’an County,where the Dabusu National Nature Reserve is located,as an example,the paper analyzes the changes in land use and landscape pattern in Qian’an County from 2003 to 2023 based on softwares such as ArcGIS,Fragstats,and SPSS.It reveals the evolution process of landscape ecological risk and discusses the correlation between the spatial density of township settlements and landscape ecological risk.Furthermore,it proposes methods for optimizing the spatial pattern,and divides the research area into restoration,improvement and control zones for targeted ecological governance,providing a useful reference for the research,governance,and planning of landscape ecological risk in the counties where nature reserves are located in China.
