摘要/Abstract

摘要： 研究了宁夏盐池四墩子人工柠条带边缘与柠条带内部和天然草地间地表甲虫多样性的差异,探讨边缘效应对地表甲虫群落的影响。调查共设9个重复样带,每个样带分别由边缘深入到柠条带内部和草地内部100 m,共设81个样点,利用巴氏罐诱法调查地表甲虫群落组成。共记录地表甲虫56种,隶属于13科,其中步甲科(17种)和拟步甲科(12种)种类最多,拟步甲科、步甲科、金龟科和鳃金龟科的个体数量,分别占总个体数量的41.78%,10.81%,10.54%和10.45%,共同构成研究区域地表甲虫的优势类群。甲虫的个体数量、多样性和均匀度从柠条带、边缘到天然草地逐渐降低,都达到了显著水平。边缘效应强度分析呈现边缘正效应(1.039 6＞1)。

Abstract: The influences of edge effects on ground-dwelling beetles (Coleoptera) across an artificial Caragana intermedia-grassland ecotone were investigated. The study was conducted in Sidunzi, Yanchi County, Ningxia, Northwest China. During the field research, a total of 1 101 beetles belonging to 13 families were collected with pitfall traps. Of these beetles, Carabidae (17 species) and Tenebrionidae (12 species) were the most abundant species. Four families dominated: Tenebrionidae, Carabidae, Scarabaeidae and Melolonthidae which accounted for 41.78%, 10.81%, 10.54% and 10.45% of the total, respectively. From artificial Caragana intermedia to the edge and then to grassland, family abundance, diversity and evenness decreased in sequence, and were significantly different between the three habitat types. Edge effect intensity on diversity of ecotone was above 1 (1.039 6), and had a positive effect.
