中文摘要:
      土壤动物是湿地生态系统的重要组成部分,对湿地营养物质循环具有重要的作用。2013年10月至2015年7月,对甘肃太统–崆峒山国家级自然保护区16个湿地斑块的土壤无脊椎动物群落特征进行了研究,共获得土壤无脊椎动物7门130类185 033只。节肢动物门(Arthropoda)和线虫动物门(Nemata)为优势类群,分别占总捕获量的47.50% 和26.08%;环节动物门和轮虫动物门为常见类群,分别占总捕获量的14.95% 和9.26%;扁形动物门、软体动物门和缓步动物门为罕见类群,分别占总捕获量的1.25%、0.66% 和0.30%。节肢动物门和线虫动物门构成了土壤动物的主体,对土壤动物群落特征起着决定性作用。16个湿地斑块中,2# 样地的土壤动物个体数量最多;7# 样地的类群数量最多,Shannon-Wiener 物种多样性指数(4.496 7)最高;14# 样地土壤动物个体数量和类群数量都最少。各样点土壤动物间的相似性指数在0.5946 ~ 1之间,表明16个湿地斑块的土壤动物群落多样性为中等不相似到中等相似,这反映了甘肃太统–崆峒山国家级自然保护区的16个湿地斑块保护状况良好,受外来影响较少;同时也反映了不同斑块之间的差异性,这些差异性与人类活动干扰有关。
Abstract:
      Soil fauna, one of the most important components of the wetland ecosystem, plays an important role in nutrient cycling of the wetland. A study on community characteristics of soil invertebrates in 16 wetland patches of Gansu Taitong- Kongtong Mountain National Nature Reserve was conducted from October 2013 to July 2015, a total of 185 033 soil invertebrates belonging to 7 phyla 130 categories was collected, among the total groups, Arthropoda and Nematoda were the dominant groups, occupying 47.50% and 26.08%, respectively; Annelida and Rotifera were the common groups, occupying 14.95% and 9.26%, respectively; Platyhelminthes, Mollusca and Tardigrada were the rare groups, occupying 1.25%, 0.66% and 0.30%, respectively. Arthropoda and Nematoda constituted the main body of soil fauna and played a decisive role in deciding the community characteristics of soil fauna. In these 16 wetland patches, sample 2 had maximum individuals of soil fauna, sample 7 had maximum taxa and the highest of species diversity index of Shannon-Wiener (4.496 7), sample 14 had minimum individuals and taxa. The similarity index among all sample plots ranged from 0.594 6 to 1, showing the community diversity of soil fauna in these 16 wetland patches was from moderate dissimilar to the medium similarity. This reflected that the protection state of these 16 wetland patches remains good and suffers little influence outside; and it also indicated that the differences among the wetland patches related to the interference of human activities.
