摘要
基于巢湖流域土壤类型图,使用ArcGIS 10.1和Fragstats 4.2,并选择5个景观格局指数,研究了巢湖流域景观格局指数随空间粒度的变化趋势,并且计算了变异系数.结果表明:巢湖流域土壤类型图最适合进行景观格局分析的空间尺度范围在30~60 m.
Abstract
Based on the soil type map of Chaohu Lake Basin,and by using ArcGIS 10.1 software and Fragstats 4.2 software,and selected 5 landscape pattern index,the article explored the trends of landscape indices with the spatial granularity of Chaohu Lake Basin,and calculated the coefficients of variation.The results showed that for the soil type map of Chaohu Lake Basin,the most suitable landscape spatial scales for the analysis were 30-60 m.
