The establishment of the indication on environmental health of butterfly and of the environmental monitoring evaluation system in Chongqing

Abstract

This is the second paper about the study of biodiversity and biological indication of butterfly in Chongqing, the purpose of this article is to set up the indication on environmental health of butterfly and of the environmental monitoring evaluation system. Basing on the previously study of the diversity parameters of butterfly in different ecological function divisions, this article focus on the research of the similarity analysis of different fauna. It has been selected 22 different diversity parameters of butterfly and 5 major environmental factors. In order to probe the selection of the monitoring index, the species and groups of indictor and to establish the evaluation system of environment, we have been analyzed them by means of regression analysis and principal component analysis. The result shows that, when observing on the region class, the diversity and evenness index of the species, genera and families in the 22 parameters could be neglected; in the 5 main environmental factors, the influence of the population pressure ( X 22 ) is more than the other four factors which respectively are the region ratio ( X 18 ) , the population density ( X 19 ) , the proportion of woodland ( X 20 ) and the amount of land containing ( X 21 ) . From the analysis of the diversity parameters, there are 10 factors that can be chosen for evaluating the
