通过对周宁县高山花椰菜的田间调查，明确高山花椰菜的田间主要害虫有小菜蛾、蚜虫、黄曲条跳甲；利用聚集度指标检验、Taylor幂法则和Iwao回归法对主要害虫进行空间分布型的研究。结果表明，聚集度指标检测不同高山花椰菜田小菜蛾和蚜虫的M oo re指标 I均＞0、聚集度指数 M倡／m均＞1、 CA指标均＞0、扩散系数C均＞1、负二项分布 K值均＞0，为聚集分布；在蔬菜田地块1、地块2、地块3的黄曲条跳甲呈聚集分布，在地块4、地块5的黄曲条跳甲种群呈均匀分布。

We investigated the population dynamics and spatial distribution of main pests on alpine Brassica oleracea L .in Zhouning county from April to June ,2013. The results showed that Plutella xyllostella ,Myzus persicae and Phyllotreta striolata are the main pests in the vegetable field. Meanwhile ,aggregation indexes and Iwao regression methods were used to explore the spatial distribution pattern on the alpine Brassica oleracea L .. Our results showed that the aggregation index of P. xyllostella and M. persicae distribution in the five different fields are I>0 ,M* /m>1 ,CA >0 ,C>1 ,K>0 ,suggesting that there has an aggregative spatial distribution of P. striolata in the field of 1 ,2 ,3 ,and uniform in the field of 4 and 5.
