Abstract: The result of study in the paper shows that the plant can grow in tailings which have the high content of copper. Soil animal is also rich in such tailings. There is a close relationship between rehabilitation of biotic community and physical and chemical property changes of tailings. With the lapse of piling time or human's administration, the increase of stabilization,the amelioration of substrate structure, the increase of water holding and fertility keeping capacities all take place in the upper layer tailings. The higher content of humus Cand total N, the more abundant soil animal's component and number are. Acarina, Enchytraeidat, Coleoptera are the dominant groups. Acarina only comes to absolute predominance in the sample plot which is more than 40 piling years old. Enchytraeidat is widly distributed.

Key words: butterfly, monitoring, Europe, case, proposal.
