福州市土地利用的景观破碎化分析

Analysis on Landscape Fragmentation of Land Use in Fuzhou

以福州市土地利用现状图为基本图件,在GIS支持下编制了福州市土地利用景观图,并在此基础上选取4种主要景观破碎化指数,通过在Excel软件中计算,定量地分析了福州市土地利用的景观破碎化特征.结果表明:福州市土地利用的景观破碎化程度较低,总体斑块密度为0.498 3个.km-2,整个区域景观斑块破碎化指数0.001;景观破碎化与人类活动休戚相关,随着人类活动的加强,景观破碎化程度也随之加深.

Based on the land use picture in Fuzhou,the landscape picture is compiled under the support of GIS and four approaches are used to analyze its landscape fragmentation. The result shows that this area is lightly fragmented. The patch density of landscape is 0. 498 3 individual·km^-2, and the patch fragmentation index of the whole area is only 0. 001. Landscape fragmentation is closely related to human activities. If the human activities are increasing on the landscape, the fragmentation level will also increase.
