| 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0.594 6~1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 is an important component of the wetland ecosystem, wetland plays an important role in nutrient cycling. From October 2013 to July 2015, a study on community characteristics of soil invertebrate in the 16 wetland patches of Gansu Taitong-Kongtong Mountain National Nature Reserve was conducted, which collected 185033 soil invertebrates belonging to 7 phyla 130 categories in which Arthropoda and Nematoda are dominant groups, occupying respectively 44.78% and 28.77% of the total acquisition amount; Annelida and Rotifera are common groups, occupying respectively14.96% and 9.3% of total acquisition amount; Platyhelminthes, Mollusca and Tardigrada are rare groups, occupying respectively 1.25%, 0.66% and 0.30%. Arthropoda and Nematoda constitute the main body of soil fauna and plays a decisive role in the soil fauna community characteristics. In the 16 wetland patches, No.2 sample plot has the most individuals of soil fauna. No. 7 sample plot has the largest number of taxa with the highest Shannon Wiener species diversity index (4.4967). No. 14 sample plot has the least individuals and taxa. The similarity index among all sample plots is between 0.5914-1 which shows the soil fauna community diversity in the 16 wetland patches are medium similar to similar. Thus, Gansu Taitong-Kongtong Mountain National Nature Reserve is in good condition with little outside influence. |
