摘要
课题组以佛山市顺德区作为研究对象,利用1992年、2002年和2012年三期遥感影像解译获取的土地利用信息,在系统分析研究区土地利用/覆被类型时空动态变化的基础上,进一步评价该地区的生态环境效应。结果表明:1)1992—2012年,顺德区土地利用格局变化较大,土地动态转移较明显,土地利用程度较高;2)从生态环境效应评价来看,顺德区综合指数呈现逐渐上升趋势,但总体上综合指数都较小,综合生态环境状况一般,反映出顺德区在研究期间生态环境处于较严峻的态势。研究结果为研究区土地资源的合理开发利用以及生态环境保护提供重要的参考。
The research group takes Shunde District,Foshan City,Guangdong Province as the research object,and uses the land use information obtained from the interpretation of remote sensing images in 1992,2002 and 2012.Then,based on the systematic analysis of the temporal and spatial dynamics of land use/cover types in the study area,the eco-environmental effects of the area were further evaluated.The results show that:1)the land use pattern of Shunde District had changed a lot from 1992 to 2012,the dynamic land transfer was more obvious,and the land use degree was higher;2)From the perspective of ecological environment effect evaluation,the comprehensive index of Shunde District shows a gradual upward trend.However,the overall index is relatively small,and the comprehensive ecological environment is average,reflecting that the ecological environment of Shunde District was in a severe situation during the study period.The results provide an important reference for the rational development and utilization of land resources and ecological environment protection in the study area.
