基于 RS 与 GIS 的开都河流域景观格局及其动态变化研究

以开都河流域为研究区域，以LANDSATTM遥感图像为主要信息源，以ENVI遥感图像处理软件、Arcgis地信软件和FRAGSTA Tversion3．3作为空间信息处理工具，采用景观空间格局等指标，对开都河流域景观格局进行了研究。结果表明，1990～2010年，开都河流域景观草地模地优势未发生改变，对区域生态环境仍发挥着重要作用。人类活动虽有加剧趋势，但由于其优势度值较低，加之区域整体人类开发水平仍处于较低的水平，故区域生态环境受人类干扰程度很小。

Study on Landscape Pattern and Dynamic Change of Kaidu River Basin Based on RS and GIS

With Kaidu River basin as the study area, the LANDSAT TM remote sensing image as the main information source, the ENVI re- mote sensing image processing software, Aregis software and FRAGSTAT version3.3 as spatial information processing tools, using spatial pat- tern of landscape index, the landscape pattern of Kaidu River basin was studied. The results showed that, during 1990 -2010, Kaidu River basin landscape lawn mode advantage does not change, has played an important role in regional ecological environment. Human activities have increased, but because of its low value of advantages, and the overall regional human development level is still at a low level, so the regional ecological environment under human disturbance degree is very small.
