| 摘 要： | 景观是保护生态环境的关键所在，考虑地震灾害对景观格局的破坏影响，模拟景观格局在地震作用后的变化情况，对于找到景观设计脆弱点意义重大。提出地震前后景观格局的变化研究，以四川都江堰地区为研究对象，基于遥感图像、ArcGIS软件和Fragstats景观计算软件，以景观单元特征指数、景观格局指数作为指标，分析该地区在2007—2008年地震发生前后景观格局的变化，为该地区的震后重建以及未来的景观规划提供参考。

| Abstract: | Landscape is key to protecting the ecological environment. Considering the destructive influence of earthquakes on landscape pattern, it is of great significance to simulate changes in landscape pattern after earthquake action to determine the vulnerability of landscape design. This paper presents research on the change in landscape pattern before and after an earthquake. Studying the Dujiangyan area of Sichuan Province, China, based on remote sensing image, ArcGIS software, and Fragstats landscape calculation software, and indexing landscape unit characteristics and landscape pattern, we analyzed the changes in landscape pattern before and after earthquakes in this area from 2007 to 2008. The study can provide a reference for post-earthquake reconstruction and future landscape regulation in the Dujiangyan area. |
