采用物种多样性、均匀性及优势度等指标测定了桃园昆虫群落的时间结构变化．结果表明，桃园昆虫群落物种数随桃树生长而增加，优势种也因其生长而变化；根据群落的相异系数对桃园４～８月的昆虫群落进行聚类和排序的分析发现，６月和７月的昆虫群落最为相似，其次是４月和５月．
The temporal structure of the insect community in Taoyuan was determined by species diversity, uniformity and dominance. The results showed that the number of insect community species in Taoyuan increased with the growth of peach trees and the dominant species also changed due to their growth. According to the clustering and sorting of the insect communities from April to August in Taoyuan, The most similar to the insect community in July, followed by April and May.
