我国东部矿区生态系统退化机理初探

煤炭开采已经给矿区生态系统带来了极大的危害，使矿区生态系统的生产力不断下降，矿区生态系统正在发生退化。华东地区是我国的主要煤炭产区，该地区为高潜水位区域，因此该地区的生态退化具有其独特性，地表塌陷引起的土壤盐渍化、地面积水、水土流失等是引起这一地区生态系统退化的主要原因。

SOME DISCUSSIONS ON THE MECHANISM OF THE DEGRADATION OF ECOSYSTEM IN MINE AREAS IN THE EASTERN CHINA

Ecosystem in mine areas has suffered great harm from coal mining.The productivity of the ecosystem has decreased gradually and the ecosystem is degrading. The Eastern China is the major producing area of coal in the China. The groundwater level of this area is high. So the degradation of the ecosystem in this area has its unique features, salinization of soil, surface water accumulation and the loss of water and soil caused by surface subsidence are the main causes of the degradation of the ecosystem in this area.
