黄河三角洲河口地区土地利用及生态环境景观分析

通过人机交互解译1996年和2004年TM影像得到2期土地利用数据,求得到土地利用转移矩阵和各种生态环境景观指数。通过分析两期土地利用及景观结构指数之间的差异性,指出由自然和人为原因引起的生态环境的变化:研究区总面积有所减少,盐碱地改良后用于了鱼虾养殖,部分未利用地和水域盐碱化,区域景观类型丰富且均匀,局部破碎严重。

Analysis on land use and eco-landscape of estuary of Yellow River delta

Based on two periods of Land Use Data obtained from the TM Images of 1996 and 2004 through the man-computer interactive interpretation,the transfer matrix of land use and various indexes of eco-landscape are given.Through the analysis on the discrepancy between the indexes of land use and landscape structure of both the periods,the change of the eco-environment caused by the causations of both the nature and the human activities is pointed out that the total area of the studying region is somewhat reduced;the alkali-saline land therein is utilized for fishery breeding;a part of the unused land and water area are basified;the sorts of landscape are rich and uniform and serious fragmentations are locally occurred.
