The paper studies composition of grasshopper community in different habitats , found that differences in family , genus and species and analyzed the causes of those . the author analyzed the following aspects by spss software and the measure of euclidean distance : ( 1 ) analyzed the relationship between grasshopper species and geographical distribution and divided 9 forestry belt into 3 main habitat model : low mountain conifer and broadleaf integrated forestry belt ; low mountain chanbai conifer forestry belt and middle - high conifer - betula ermam / - tundra belt ; adopted sum of deviation of square to clustered ecological species groups , and thus divided 48 grasshopper species into 3 main category , 12 ecological species groups
在长白山地区蝗虫生态分布特点的研究中，主要应用spss软件包、采用euclideandistance测度法对以下两方面内容进行了分析： ( 1 )对长白山地区蝗虫地理分布关系进行了分析，将长白山9个林带划分为三大生境型：低山针阔叶混交林带、低山长白松林带和中高山针叶?岳桦?苔原复合体； ( 2 )利用离差平方和法对生态种组进行等级聚类，结合实地调查结果，将48种蝗虫划分为三大类12个生态种组。
