枣园节肢动物群落的时间动态

将枣园节肢动物群落视为一个整体,根据群落内物种的组成和数量,采用不同群落参数和群落分析法对太谷地区枣园节肢动物群落的时间格局进行了比较。结果表明,影响枣园节肢动物群落时间格局的主导因子及时间格局分化较为明显。可将枣园节肢动物群落在时序上分为发展期、过渡期、鼎盛期和衰减期4个阶段,并结合气候、物候变化,讨论了各阶段群落的发生特点和主要害虫的治理对策。

Temporal pattern of arthropod community in jujube orchard

This paper analyzed the temporal pattern of the arthropod community in jujube orchard in Taigu area of Shanxi Province, regarding this community as a whole and in the light of its species constitution and amount. The results showed that the test arthropod community could be temporally divided into 4 stages, i.e., developmental, transitional, prosperous, and declining. Based on the climatic and phonological conditions at each stage, the development characteristics of the arthropod community as well as the management strategies of its dominant pests were discussed.
