中文摘要：

以2011年朱溪小流域SPOT卫星遥感影像为数据源,结合野外实地考察,运用GIS手段对研究区遥感影像进行人机交互解译,得到研究区2011年的土地利用景观类型图,并将朱溪小流域分割成东、中和西三部分.运用FRAGSTATS3.3软件,对东、中和西三部分的景观格局特征进行分析.结果表明：朱溪小流域东、中和西部之间存在较大的景观差异.从东部到西部,最大斑块指数、斑块平均面积指数下降,说明西部地区的破碎度大于东部地区;从景观规则性上来看,斑块数总体呈上升趋势,西部到东部景观面积加权平均形状指数、面积加权平均分维数明显增加,表明斑块的形状趋于复杂化,不规则化;从东部到西部香农多样性指数SHDI、香农均匀度指数SHEI整体上呈上升趋势,景观类型所占比例差距逐渐减小且各组成在面积上分布越来越均匀.

英文摘要：

Based on field survey and spatial date sampled in the Zhuxi Small Watershed on 2011,remote sensing image of the study area was interpreted through interactive man-computer by using the method of GIS.This way can get the land use maps of the study area in 2011 and Zhixi Small Watershed was cut into three parts（east,middle,west） by the software ArcGIS.The landscape pattern of land use from the eastern to western was analyzed by the software FRAGSTAS3.3.The result shows that there is a big difference between eastern and western on the Zhuxi Small Watershed landscape.It explains that the western part ＇s fragmentation is bigger than western part because largest patch index and area-mn index are reducing from eastern part to western part;from the perspective of landscape rules,the patch number is more and more big on the whole and the patch average area index and shape index are increasing obviously from western part to eastern part,which can show that the patch shape became complex and random;SHDI and SHEI are on the rise on the whole from eastern part to western part,so the gap of the landscape types is more and more small and area distribution is more and more fairly welldistributed.
