基于景观生态学原理的区域生态格局优化研究OA

Building an urban ecological security pattern is crucial for maintaining national and regional ecological security and is the core foundation for achieving sustainable urban development.This process is not only a fundamental condition for ensuring ecological security,but also a key pathway for promoting the continuous progress of cities.Based on land use type data of Yantai City from 2000 to 2020,this paper uses ArcGIS and Fragstats software for data processing and calculations,and employs landscape pattern index analysis method to analyze the area changes,patch attributes,grain size structure,and their dynamic changes of various landscape elements in the study area.It reveals the landscape pattern evolution process of Yantai City over multiple periods,and expounds the dynamic characteristics of patch size changes of landscape elements and their correlation with landscape pattern indices.This paper has revealed the intrinsic connection between regional ecological security patterns and land use patterns,and has proposed the corresponding ecological pattern optimization strategies for their dynamic change processes,providing a reference for the optimization of landscape patterns,habitat protection,and sustainable development in coastal cities.
