摘　　要：由于适宜水禽栖息的生境面积不断缩小,致使湿地生态系统受到严重破坏,生物种群数量急剧下降。通过野外采点调查建立可靠的栖息地适宜点群。基于遥感和GIS空间技术获取20个评价因子,并结合二项Logistic回归模型,构造出基于像元水平的栖息地适宜性模型,经过筛选后保留对适宜性影响力较大、拟合优度高的10个评价因子,分别从社会人文、植被长势和地形地貌三大方面分析。再应用K-means聚类分析法将适宜性点群分级,得到建三江区栖息地适宜性评价分级图,有效分析适宜性5个等级的空间尺度,其中最适宜栖息,中适宜栖息,基本适宜栖息,不适宜栖息和不可用地分别占总用地的24.73%,17.69%,29.8%,17.62%和10.16%,前三类占总的72.22%。说明建三江区的适宜水禽栖息的用地较多,主要分布在流域、低河漫滩等人为干扰少的湿地沼泽平原,此研究对水禽生境的保护和可持续发展都具有指导意义。waterfowls habitat and population quantity has been seriously damaged due to continuously deteriorating of Wetland ecosystem.There are satisfactory variety of ecosystems,and there are resources and abundant plants or animals species in the Jiansanjiang area.Although the biodiversity of the region is rich and important,it is suffering from man-made destroy and disturbance.Analysis of high strength wetland reclamation process and environment changes was conducted to study the direct and indirect effects on wetland waterfowls habitat.People were raised to pay attention to the protection of Wetland and Biodiversity extensively.Habitat suitability method is widely applied in natural land resource management,especially it is very meaningful research for biodiversity protection and useful spaces question of animals.It has also very important significance to quickly realize and determine the best habitat position in spatial scale domain.Jiansanjiang area lies in the northwest of Heilongjiang Province in China,as for most of the year,where the climate is characterized as temperate semiarid continental monsoon.There are three large rivers in the region,including Heilongjiang River,Songhua River and Wusuli River,which are important national wetland in Sanjiang Plain.The maps of topographic and vegetation distribution in Jiansanjiang area following as reference materials,it is an application of GPS on field control point position established habitat suitability point cluster.The acquisition of 21 single evaluation factors is based on information extraction by remote sensing and Geography Information System spatial analysis method,and analysis of Binary Logistic regression model,which was integrated into habitat suitability module on pixel levels.Along with other factors,these was a great influence,high goodness-of-fit and big standardized residuals on 10 single suitability evaluation factors finally,synthetically evaluated by settlement density,population density,road Euclid Distance,settlement Euclid Distance,NDVI,vegetatio
