摘　　要：2008年3—6月和2009年3—6月,应用分层抽样和定点观察的方法,对黑龙江大沾河自然保护区白头鹤(Grus m onacha)的空间分布特征进行了调查研究,并根据白头鹤分布与生境因子特征,判断白头鹤对生境因子的选择性,同时,利用G IS技术对白头鹤生境的适宜性进行了综合评价。生境类型对白头鹤活动分布的影响作用最大(S4=1.443),其次是植被指数(S3=1.383);影响最小的两个因子分别是坡向(S6=0.065)和斑块复杂性(S2=0.208)。白头鹤多选择斑块面积较大(V1=0.33)、植被盖度(指数)较大(V3=0.65)、距离河流较近(V9=0.77)的区域作为生境。综合评价结果表明,大沾河湿地保护区内适宜的白头鹤生境达到54.5%,其中最适宜生境为15.2%,生境适宜区域主要位于河流及附近的沼泽区域。Stratified sampling and fixed observation methods were used to investigate the spatial distribution of Hooded Crane in Dazhanhe Nature Reserve,Heilongjiang Province.Habitat selection of Hooded Crane and the importance of habitat factors were analyzed in terms of the habitat properties used by Hooded Crane,and habitat suitability was evaluated based on GIS techniques.Habitat type is the most important factor influencing the distribution of Hooded Crane with the standard Logistic regression index（S4） of 1.443,and the second is Normalized Difference Vegetation Index（NDVI）（S3=1.383）.Slope aspect（S6=0.065） and patch complexity（S2=0.208） do not show an important impact on Hooded Crane.Habitats with larger patch area（V1=0.33）,high vegetation cover（V3=0.65） and close to water（V9=0.77） are more frequently used by Hooded Crane.The area percentage of suitable habitat for Hooded Crane in Dazhanhe Nature Reserve is 54.5% with the most suitable habitat of 15.2%.The suitable habitats are close to river or marsh.
