摘要
采用物种多样性、均匀性、优势度指标测定柠檬．园昆虫群落的时间结构变化。结果表明，柠檬园昆虫群落物种数、多样性指数、均匀性指数以及优势种群随时问的变化而变化。在柠檬生长旺期（3—6月）柠檬园昆虫多样性指数和均匀性指数较高，群落结构较稳定。根据群落的相异系数对柠檬园1～12月昆虫群落进行分析表明，7月与12月的昆虫群落最为相似，其次是2月与8月。
The time structure of insect communities in lemon orchard was measured using three kinds of indices of species,including diversity, evenness and dominance. The results showed that species number, diversity indices, evenness and dominance species varied over time. During the period from March to June, diversity and evenness were higher in the lemon orchard, Insect community was more stable. According to the results from analyzing the insect community in lemon orchard from January to December,the insect community was the most similar between July and December,the next was between February and August.
