泾河流域(平凉段)重金属污染对土壤线虫生态特征影响的研究
Effect of Heavy Metal Pollution on Ecological Characteristics of Soil Nematodes in Jinghe River Basin(Pingliang Section)
摘要
Abstract
Through the detection and analysis of soil heavy metal pollution,the ecological diversity and community structure changes of soil nematodes in this region were discussed,which provided the theoretical basis for promoting the sustainable development of ecological environment in this region.The heavy metal content in soil samples was measured and the heavy metal pollution index was calculated at the sampling points along the river.Soil nematodes were separated and classified into families and genera,and the c-p groups of various nematodes were calculated.The correlation between soil nematode ecological index and heavy metal pollution index was analyzed.The content of Zn was the highest and the content of Cd was the lowest in soil samples.The sampling points 23 and 45 were slightly polluted with Zn and Cd.A total of 10 402 nematodes were isolated from all samples,and the largest number of nematodes was Brachysoma.The c-p1-c-p2 group accounted for the largest proportion(57.71%).Shannon-Wiener diversity index H'was negatively correlated with heavy metal pollution index.It indicated that heavy metal pollution could affect the quantity and species of soil nematodes.With the increase of heavy metal pollution,the Shannon-Wiener diversity index H'decreased significantly,and the diversity of soil nematode species decreased.关键词
