摘要

On the basis of MSS and TM remote sensing data of 5 study periods during 1975-2002 as well as geographic data of Beijing City,evolution laws of landscape components and corresponding changes of the ecological environment are discussed through image processing and GIS analysis.The results show that structure of landscape eco-component changes greatly during the 27 study years,natural landscape components slightly increase,semi-natural landscape components drastically decline,humanistic landscape components increase fast and are mainly transformed from semi-landscape components,that is to say,urban construction land occupies a great number of farmland,and human interventions are serious;moreover,transformation among landscape components is also frequent in all study periods,semi-natural landscape components witness the largest transformation ratio,so semi-natural landscape components are a kind of relatively instable one in Beijing.In terms of eco-environment,natural landscape components within the city increase which is specifically demonstrated as increase of water,urban green space and vegetation coverage;compared with the data in 1975,it is obvious that eco-environment quality of Beijing is gradually improving,and urban environment quality also promoted.
