title: [Structural characteristics of arthropod community in grapery].
abstract: By the method of principal component analysis, this paper analyzed the characteristic parameters of arthropod community and its phytophagous and predacious sub-communities in grapery. The results showed that in the first principal component, the contribution of arthropod community, phytophagous sub-community and predacious sub-community was 66.70%, 73.39% and 54.17%, respectively. For arthropod community, the absolute values of normalized regressive coefficients of individuals' number N, Hill diversity index N1, Hill diversity index N2 and McIntosh index D(mc) were larger, indicating their greater contribution on the community. For phytophagous sub-community, N, N1, N2, N and S (total species) had greater contribution; while for predacious sub-community, the greater contribution was made by N1, N2, Shannon-Wiener diversity index H' and abundance R. Synthetically, N2 and N1 had greater contribution on the arthropod community and its phytophagous and predacious sub-communities in grapery, comparing with other characteristic parameters.
