南部县升钟水库库区景观格局现状分析与评价

A Study of the Landscape Patterns of Shengzhong Reservoir in Nanbu County

本文结合"3S"技术,利用景观格局分析软件Fragstats3.3,分别从斑块类型水平指数和景观水平指数两个方面对南部县升钟水库库区景观格局现状进行分析与评价。结果表明,研究区林地(针阔混交林、针叶林)和耕地(旱地、水田)控制着整个景观类型,呈现出林地与耕地交错的结构特征。该区域的景观类型丰富,多样性程度高。但是斑块数量多,破碎化程度高,而且景观类型的形状不规则,复杂程度高。林地作为研究区的基质,其面积偏小,并且受到较大程度的人为影响。

In this paper,by the ＂3S＂ technology and the software Fragstats 3.3 of landscape pattern anal, ysis, the landscape patterns of the area of Shengzhong Reservoir in Nanbu County were analyzed and evaluated in two aspects of patch-level index and landscape-level index. The results showed that the landscape types were rich and the landscape diversity was abundant. But because of a relatively large number of patches, there was a higher fragmentation of landscape in the studied area.
