| 摘 要： | 采用物种多样性、均匀性、优势度指标测定梅园昆虫群落的时间结构变化.结果表明,梅园昆虫群落物种数、多样性指数、均匀性指数随季节推移而增加,优势种群也随季节而变化.主成分分析表明,食叶性昆虫及刺吸性昆虫在群落中具有重要作用,刺吸性昆虫与捕食性昆虫发生发展趋势相同;根据群落的相似系数进行聚类和排序分析发现,9月、10月、11月和12月份的昆虫群落最为相似,其次是4月、5月、6月和7月份昆虫群落,再者3月份的昆虫群落,最后是8月份的昆虫大群落.图3表3参17

| Abstract: | The time structure of insect communities in plum orchard was measured using three kinds of indices of species, including diversity, evenness and dominance. The results showed that species number, diversity indices, and evenness increased, and the dominant species varied over time. The principal component analysis showed the leaf-eating insect and the predacious insect played important roles in the insect community. The sap-sucking insect and the predacious insect had the same development trend with time course. Using cluster and two-dimensional ordinal analysis, and based on resembling the coefficients it was found that the community in December, November, October and September was the most similar, then in April, May, June and July, next in March, and finally in August.
