基于Fragstats的城市土地利用景观格局分析--以安徽省舒城县为例

景观格局指数是描述景观空间特征的重要指标,也是最为简单和直观展现景观空间动态变化趋势的指标。本文以安徽省舒城县为研究对象,借助ArcGIS10.2软件将舒城县2000年、2010年和2020年三期土地利用覆被数据进行预处理,结合舒城县现状特征选取适当的景观格局指数,并在Fragstats4.2软件里进行指数运算,再利用ArcGIS软件进行空间数据统计与分析,最终得到2000-2020年间的舒城县土地利用景观格局的时空分布特征。以此为舒城县土地利用景观空间结构布局发展提供借鉴与参考。

Landscape pattern index is not only the important indicator to describe the characteristics of landscape space,but also the most simple and intuitive indicator to show the dynamic change trend of landscape space.This paper takes Shucheng County,Anhui Province as the research object,preprocesses the land use and cover data of Shucheng County in 2000,2010 and 2020 with the help of ArcGIS 10.2 software,selects the appropriate landscape pattern index based on the current characteristics of Shucheng County,performs the index calculation in Fragstats4.2 software,then uses ArcGIS software to carry out spatial data statistics and analysis,and finally obtains the spatial and temporal distribution characteristics of land use landscape pattern in Shucheng County from 2000 to 2020,which can provide reference for the development of spatial structure layout of land use landscape in Shucheng County.
