图5 野鸭湖湿地不同植被类型地表甲虫群落活动密度、科丰富度和多样性指数与综合环境变量WBC的关系。其中变量WBC为对9个环境因子进行主成分分析(PCA)得到的第二主成分, 反映了土壤含水量、植物生物量和盖度3个环境因子的综合影响。各样地编号同图3
Fig. 5 The relationship between activity density, family richness and diversity index of ground-dwelling beetle communities and the synthetic environmental variable (WBC) in Yeyahu Wetland. The variable WBC (Water-Biomass-Coverage), which reflects the situation of soil water content, plant biomass and coverage, is the second component obtained by PCA of nine environmental factors. The labels of sampling sites are the same as those in Fig.3.
