中文摘要	在干旱风沙区宁夏盐池县,选择典型放牧柠条锦鸡儿灌丛林地为研究样地,以邻近长期围栏封育灌丛林地为对照,调查了春季、夏季和秋季放牧和封育2种类型样地的地表植被、土壤性状和地面节肢动物分布特征,分析了灌丛林地地面节肢动物群落组成及多样性对放牧管理的响应规律.结果表明:1)放牧导致植被高度、土壤细砂粒含量和土壤电导率显著降低,而土壤容重和粗砂粒含量显著升高.2)调查共获得地面节肢动物13目40科,其中优势类群为蚁科和拟步甲科,其个体数占总个体数的68.75%;常见类群4类,其个体数占总个体数的20.82%;其余34类为稀有类群,其个体数占总个体数的10.44%.在春季、夏季和秋季,放牧和封育样地间地面节肢动物群落组成均差别较大,反映了地面节肢动物对包括放牧管理和季节变化双重作用下环境变化的敏感性和适应性.3)放牧导致地面节肢动物多度显著升高.但放牧样地和封育样地间地面节肢动物类群数、Shannon指数、均匀度指数和优势度指数在3个季节中均无显著差异.4)相关分析表明,地面节肢动物多度、均匀度指数、优势度指数均与植被高度、植物多度、土壤水分、土壤pH值和电导率存在相关性,而地面节肢动物Shannon指数与植被高度、土壤水分和土壤细砂粒存在相关性.偏冗余分析(RDA)表明,土壤pH值、植物多度、土壤含水量和温度是影响地面节肢动物群落个体数分布的关键驱动因子.研究表明,放牧管理条件下植被高度、土壤pH、土壤水分和土壤温度差异导致不同地面节肢动物类群表现出了不同的响应模式.灌丛对地面节肢动物多样性的保育效应能够削弱放牧干扰的负向影响.但放牧干扰下春季灌丛林地植食性地面节肢动物多度增加,需注重放牧易导致灌丛林病虫害发生和进行防控.
英文摘要	We investigated the community structure of ground-active arthropods as well as vegetation and soil properties in Caragana shrub plantations under grazing and exclosure management across spring,summer and autumn in Yanchi County of Ningxia in northern China. The aim of this study was to uncover the responses of ground-active arthropods in shrub plantations to grazing management in desertified regions. The results showed that: 1) plant height, soil fine sand content, and soil electrical conductivity were significantly lower, whereas soil bulk density and coarse sand were significantly higher in shrub plantations under grazing than exclosure. 2) There were 40 families from 13 orders captured. The dominant groups included Formicidae and Tenebrionidae families, which comprised 68.75% of the total individuals. There were four common groups occupying 20.82% of the total individuals. The remaining 34 groups were relatively rare, only accounting for 10.44% of the total. Across the three seasons, the composition of ground-active arthropod community was significantly different between grazing and exclosure,which indicates the sensitivity and adaptability of ground-active arthropods to environmental changes including grazing management and seasonal changes. 3) There was a significant effect of grazing on total abundance of ground-active arthropods in shrub plantations, with significantly higher values under grazing than under exclosure. There was no significant effect of grazing management on group richness and diversity of ground-active arthropods in shrub plantations. 4) There was a correlation of total abundance, evenness index and the Simpson index with plant abundance, vegetation height, soil moisture, soil pH and electrical conductivity. There was a significant correlation of the Shannon index with vegetation height, soil moisture and soil fine sand. Plant density, and soil pH, soil moisture and soil temperature were the key factors driving the structure of ground-active arthropod communities in shrub plantations under grazing management across seasons based on the partial RDA results. It was concluded that the variations of plant height,soil pH,soil moisture and soil temperature under grazing management could result in different ground-active arthropod taxon to changing habitats. The conservation effect of shrub on ground-active arthropod could reduce the negative impacts of grazing. Spring grazing could enhance ground-active arthropod abundances in shrub plantations. It was necessary to pay attention to prevention of insects which are caused by spring grazing in shrub plantations.
