摘要

利用景观分析软件Fragstats3.3和半城子水库流域2000年、2005年的遥感影像解译结果

分析了2000-2005年间流域森林景观格局时空变化特征。结果表明

2000-2005年期间

半城子水库流域始终以林地为基质

且针叶林、阔叶林、混交林的优势度较高

斑块间面积分布不均匀; 在景观异质性方面

针叶林的异质性显著增高

林地类型的斑块复杂性也高于其余景观要素类型

各景观要素的斑块数目增多

分布更为均匀; 在空间相互关系方面

景观破碎化程度增加

景观水平上整体空间聚集性降低。

Abstract

Using Fragstats 3.3 and interpreted results of remote sensing images in Banchengzi Reservoir watershed in 2000 and 2005

changes of forest landscape pattern is obtained. Results showed that forest land is the matrix of Banchengzi Reservoir watershed from 2000 to 2005. Dominant index of coniferous and broad-leaved and mixed forest is higher than other landscape elements. The area of the patches is distributed unevenly. In landscape heterogeneity aspect

the heterogeneity of coniferous forest is increased; patch complexity of forest is higher than other landscape types; patch quantity of landscape elements is enhanced; and landscape elements are distributed more evenly. In spatial inter-correlation aspect

landscape fragmentation is increased and whole spatial aggregation of landscape level is reduced.
