Abstract:

In order to filtrate the scientific basis about soil sinusia concluded from super enrichment plants, the author chose Dabaoshan mine Baxin area on the pollution of abandoned farmland’s 5 repair plants in natural and an artificial plant to do research on the soil animal community structure and diversity under the root, by using the Tullgren method, were identified 168 animals, belonging to 2 phyla, 7 classes, 12 orders and 4 species of larvae. The results showed that: the pollution of heavy metal ions (Cu, Cd, Zn) and the acid soil, was the main reason that community structure of abandoned farmland animals was so simple. Different plants’ roots produced different effects on the soil animals’ community structure, it showed that the soil animal community structure under Blechnum orientale Linn., Neyraudia reynaudiana (kunth.) Keng, Chinese cabbage, and Panicum repens Linn. 4 plant roots were relatively complex and high diversity index structure, and diversity of soil animal under Phragmites australis (Cav.) Trin. ex Steud., Saccharum arundinaceum Retz. was lower, and bare ground under roots was the lowest. Vegetation roots with soil animal community structure was different-common groups and rare groups of soil animals under roots of different vegetation was quite different.
