摘  要：
应用群落多样性特征指数和冗余分析法(RDA),对黔西南老万场金矿区苔藓结皮表土原生动物群落与环境因子的关系进行了研究。结果表明:黔西南老万场金矿区矿渣、矿土和矿区周围裸露石灰岩等样地的苔藓结皮表土原生动物群落中种类数为49种,隶属35属28科,大多数种类丰度较低;群落多样性指数和RDA分析表明,金矿区苔藓结皮表土原生动物群落变化受多种环境因子的影响,重金属综合污染、pH是影响原生动物群落特征的主导因子(P<0.01);原生动物群落种类丰富度和丰度随重金属综合污染指数的增大而明显降低。通过排序分析表明,在重金属污染的金矿区,化学因子比物理因子对原生动物群落的影响更明显。

摘  要：
By using community diversity index and redundancy analysis (RDA),the protozoa communities in the moss crust in Laowangchang gold mine area of southwest Guizhou and their relations with environmental factors were studied. A total of 49 species belonging to 35 genera and 28 families were identified,most of which had low abundance. The variations of the protozoa communities were affected by various kinds of environmental factors,among which,heavy metals pollution and pH were the dominant factors (P<0.01). The species richness and abundance of the protozoa communities declined with the aggravation of heavy metals pollution,and the effects of chemical factors were more obvious than those of physical factors.
