文摘内容 The probaility of crane living in reedy wetlands can reach 100%, at the same time,the area of reed ,the water level and adjacent water area are main factors which control the crane''''''''s habitat selection.We all know that all these factors are spatially heterogeneous.For the Xianghai wetland safety and to protect the Xianghai wetland habitat of crane,this paper has mainly identified a solution to these problems.The wetland in formation is extracted from the TM images,which reflect the whole wetland landscape and are very important for both quantitative analysis of remote sensing observation of the earth system and positioning analysis in GIS database that is automatically extracted from DEM.The DEM for Xianghai characteristics of topography is created.On the basis of the GRID SUBMODULE,applying the GIS spatial overlay analysis,the relationship between the water level and the reed area below the water level and the rating distribution maps of reed area above water level is established ,When the water level reaches the altitude of 165 n ,the reed area,981.2 ha is maximum,i.e., the water level of 165 m is the optimal。
