摘    要:通过对野鸭湖湿地的Landsat—TM影像和印度的IRS影像进行融合处理,得到卫星影像分类图。结合实地调查,标定土地利用类型,运用ArcView的解译及数据统计功能,分析研究野鸭湖湿地6年来土地利用/土地覆盖的变化。研究结果表明:耕地、居民点及工矿用地面积增加,水域面积减少,湿地生态环境受到严重破坏。其主要是由自然条件、人口和经济增长所致。水域面积、植被覆盖率的减少,使栖息和越冬鸟类丧失了大量的栖息地。为保护湿地环境,应逐步退耕还草、还林;恢复芦苇、沼泽,确保区内生态平衡和系统生态质量不断优化。

关 键 词:野鸭湖湿地  遥感数据融合  土地利用  土地覆盖

Abstract:In the past 6 years, the land use and land cover of Yeyahu River have been marked with the increase of arable land?residential and industrial area, and the decrease of water area year after year. In order to put forward countermeasures to balance the land use and land cover in the Yeyahu River, this paper fuses the Landsat-TM image with the IRS image to construct the classified satellite image, identifies the land category by the means of field survey, and then introduces the ArcView to interpret and statistic the classified satellite image to search the changing rules of the land use and land cover in Yeyahu River.With the increase of arable land, residential and industrial area, and the decrease of water area, the environment of Yeyahu River has been damaged dramatically. The natural condition, population increase and economy development are mostly responsible for these damages. The decrease of water area and plantation made many resident birds can not find a place to live through the winter. The pricking up of inning also damaged the environment around the Yeyahu River. For the protection of environment, it is necessary to return the land to nature, get back the bulrush and swamp, and keep the ecosystem in balance.
Keywords:RS and GIS  Fusion  Land use and land cover  Wetland  Yayahu lake
