本文采用2011-2013年在蒲江县柑桔园(杂柑)调查数据,对生物多样性(PIE),均匀度(V’),优势度(C),物种数(S)和总体个数(N)5个昆虫群落生态指标进行定量分析。结果表明:柑桔园(杂柑)昆虫群落结构随杂柑树龄(苗期→2年生→5年生→10年生)的增加而不断演替;防治措施是影响柑桔园(杂柑)昆虫群落演替的主要因子,绿色防控技术是保持桔园昆虫群落结构多样性和维护昆虫群落结构稳定的关键因子;4-6月柑桔园(杂柑)昆虫多样性、均匀度、丰富度和样本总数均相对最高,是防治的关键时期。
Based on the survey data of citrus orchards in Pujiang County in 2011-2013, this paper analyzed the relationship among biodiversity (PIE), evenness (V), dominance (C), species number (S) N) five insect community ecological indicators for quantitative analysis. The results showed that: the structure of citrus orchard (hybrid citrus) insects community succession continued with the increase of the age of the hybrid citrus tree (seedling → 2-year-old → 5-year-old → 10-year-old) The main factor of succession and green control technology are the key factors to maintain the diversity of insect community and maintain the structural stability of insect community. The insect diversity, evenness and richness of citrus orchard The total number of samples is relatively high, is a critical period of prevention and treatment.
