摘要
本文以2019年崇礼地区遥感影像为基础,运用ArcGIS对研究区景观进行分类,并运用Fragstats软件从斑块类型与景观尺度上选取指标计算景观格局指数,对崇礼区森林景观进行景观格局分析。结果表明:崇礼区森林景观多样性水平高但景观破碎化程度高,荒草坡面积占比较高,而针阔混交林、针叶混交林、果杏面积很小,需要调整当地的景观类型,增加覆被面积。整体景观斑块间连通度较高,但有一定的优化空间。
This paper based on the class II forestry survey data in Chongli District in 2019, by using Fragstats to select indicators from class and land scale to calculate the landscape pattern index, and analyzing the landscape pattern of forest landscape in Chongli district. The results show that the forest landscape diversity level in Chongli district is high, but the degree of landscape fragmentation is high, and the area of barren grass slope is relatively high, while the area of coniferous and broad-leaved mixed forest, coniferous mixed forest and fruit apricot is very small. It is necessary to adjust the local landscape types and increase the coverage area. The overall landscape patches have high connectivity, and there is a certain optimization space.
