摘    要:应用种-面积关系模型,计算出宁夏荒漠草原蝗虫群落最小调查面积;通过2×2联列表,用点相关系数和相关系数公式对蝗虫种间分布关系进行分析,用模糊聚类法将调查蝗虫划分为4个类群;以6项聚集指标和新提出的混合度指数,对9种蝗虫种群及群落分布型进行了分析,用主成分分析法进行了排序归类。最后依据种群数量、混合度指数、分布型相似性提出群落格局的“主导分布型”新概念,认为宁夏束颈蝗种群分布型为宁夏荒漠草原蝗虫群落空间格局的“主导分布型”

关 键 词:荒漠草原  蝗虫  群落  空间格局

Abstract:The model of species area relationship for grasshoppers on the desert steppe was used to determine the minimum area.The relationship among distributions of the grasshoppers was analysed using Point Correnlation coefficients and Correlation Coefficients resulted from the four fold table.The spatial patternes of the community and of the dometant species of grashopper were analysed using the six aggregation indices.Based on frequences of species and individuals of grasshopper presented in the sampler,the aut...
Keywords:spatial pattern  grasshopper community  desert steppe
