摘　　要：通过采用聚集度指标的方法,对草地和莴笋地蜘蛛优势种的内分布型进行了比较研究,测定结果表明其内分布型与栖境的异质性大小有关。为蜘蛛的保护和利用提供了理论依据,为害虫综合防治策略的制定提供了一些有意义的信息。The internal distribution patterns of dominant spiders in asparagus-lettuce field and grassland were compared by aggregation index. The results showed that the internal distribution patterns of dominant spiders are related to their heterogeneity of habitat. This result offered theoretic basis for the protection and application of spiders, and also provided some significant information for making integrated control strategies of insect pest.
