| Abstract: | In this paper three kinds of ordination methods, polar ordination (P0), principal components analysis (PCA) and fuzzy grouping analysis (FGA) are used to study the insect community of ten typical type of grassland in Alty region. The result indicates that insect communities of grassland are in relation to the type of grassland rich degree of vegetation in grassland and humidity of living enviornment. The relationship between in sect communities of grassland and degeneration of grassland and the pest management of grassland are discussedhere. |
