摘要： 系统调查了河北南部两种不同类型杨树苗圃地下害虫昆虫群落结构组成。水浇地苗圃地下害虫优势种为小黄鳃金龟，旱地苗圃优势种为黑绒鳃金龟；水浇地杨树苗圃地下害虫群落丰富度、个体数和多样性指数都高于旱地苗圃。在春季，地下害虫的种类和数量在不同的土壤深度随时间变化而变化，从2月下旬到4月中旬，0~5cm的昆虫种类和数量不断增加，10~20cm地下害虫呈下降趋势。

Abstract: Soil-inhabiting pests community structure composition in two different type nurseries of poplar in the north of Hebei province was investigated. The dominance pest species in irrigated nursery is Metabolus flavescens Brenske and the dominance in drought nursery is Maladera orientalis Motschulsky. The species abundance, individual amount and diversity index of soil-inhabiting pests in irrigated nursery are higher than that in drought nursery. In spring, the kinds and the quantity of the soil-inhabiting pests change in different depth of soil along with the seasonal alternation. The kinds and quantity of the underground pests in 0-5cm depth increase and the soil-inhabiting pests in 10-20cm depth unceasingly decrease during the last ten days of February and the middle ten days of April.
