彭阳县不同生境地表甲虫群落多样性结构分析

摘要

An investigation on the community structure and diversity of the ground dwelling beetles under 4 different biologi-cal environments in Pengyang County in Ningxia were carried out using pitfall trap method. The results showed that a total of 590 beetles were collected, they belong to 9 families. The richness index and diversity index of the combination of the grass and arbor in semi natural woodland were the highest but those in the artificial forest were the lowest. The evenness index in the area of combining the trees and shrubs was the highest but that in the arbor forest B3 was the lowest. The species diversity degree in the artificial forest was the highest but that in the area of combining grass and arbor was the lowest.%应用巴氏罐诱法对宁夏彭阳县的4种生境地表甲虫群落结构及多样性进行了调查。结果显示，共采集甲虫标本590号，隶属9科；半天然林地的乔草结合地丰富度指数和多样性指数最高，人工林地最低；均匀度指数乔灌结合地最高，乔木林B3最低；物种多样性程度人工林地最高，乔草结合地最低。
