%X Researchers and managers pay great interest in the combined use of Geographic Information System(GIS)and Multi\|variable analysis.In this research,ring\|necked pheasants' nesting habitat was modelled based on Mahalanobis distance by using GIS.In 1997 and 1998,fifty\|one nests of wild ring\|necked pheasants were discovered and orientated in Gansu,China.Distances from nests to 14 habitats'edges,measured by GIS,were used as habitat characteristic variables.Terrain factors of elevation,slope and aspect were calculated basing on digital elevation model.We generated raster layer of every variable,and calculated Mahalanobis distance value for all the grids by using GIS.The result shows that the areas,which are similar to the known used areas at the significance level of 0.95,cover only 0.68% of the whole region.On the other hand,the dissimilar areas( P <0.05) occupy 79.08% of the total area.There are many differences of habitat composition and terrain characteristics between nesting areas and non\|nesting areas.Farmland and Grass Mountain Slope occupy very large proportion in the nesting habitat.Compared with non\|nesting habitat,the nesting habitat is of lower elevation,more gently slope and more southeast\|facing aspect.In a special habitat,nesting area and non\|nesting area are also of great distinction.The nesting area is usually near to the edge of the habitat.The types of a special habitat's neighbouring habitats will affect pheasants'selection on some region in the habitat for nesting.
