THE STUDY ON SPATIAL PATTERN OF GRASSHOPPER COMMUNITY ON THE DESERT STEPPE IN THE NINGXIA
荒漠草原蝗虫群落空间格局的研究

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...
