| 摘 要： | 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，无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无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。 |
| 关 键 词： | 物种多样性 均匀性 优势度 桃园 昆虫群落 |

| Abstract: | The time structure of insect community in peach orchard was measured with such indexes of species as diver- sity,evenness and dominance. The results showed with the growth of peach tree that the number of species was increas- ing, and the dominant species varied. According to community component from all developing periods of plants, it was found by cluster and two-dimensional ordinal analysis based on unsimilarity coefficient that the community in June was most similar to that in July,next comes that in April and May. |
| Keywords: | insect diversity evenness dominance peach orchard |
