蓝田工业区大型土壤动物群落结构与土壤因子的研究

Study on Community Structure and Soil Factors of Large Soil Animals in Lantian Industrial Area

该研究对西江流域羚山涌河道沿岸蓝田工业区的大型土壤动物群落结构和土壤重金属进行了调查。结果表明,大型土壤动物2419只,隶属3纲9目,大型土壤动物个体数与土壤含水率、土壤温度呈正相关,与土层、土壤最大孔隙度、土壤容重呈负相关;大型土壤动物类群数与土壤含水率呈正相关,与土层、土壤温度呈负相关。研究区Cu、Zn、Cd、Pb单项污染指数和综合污染指数均大于1。

The community structure of large-scale soil animals and heavy metals in Lantian Industrial Zone along lingshanchong River in Xijiang River Basin were investigated.The results were as follows:2419 large-scale soil ani⁃mals were captured,belonging to 3 classes and 9 orders.The individual number of large-scale soil animals was posi⁃tively correlated with soil moisture and soil temperature,negatively correlated with soil layer,maximum soil porosity and soil bulk density;the group number of large-scale soil animals was positively correlated with soil moisture and negatively correlated with soil layer and soil temperature.The single pollution index and comprehensive pollution in⁃dex of Cu,Zn,Cd and Pb in the study area are greater than 1.
