论煤矿城市塌陷区和露天采矿区的生态重建战略问题

The Ecological Reconstruction Strategy of the Subsidence Land Caused byCoal Exploitation and the Areas of Surface Mining of Coaleconomy Cities

煤炭城市在地下和露天采矿过程中，都要形成大面积的土地塌陷、水污染等生态破坏问题，而我国沙漠地区、黄土高原区、北方平原区、南方多雨地区和煤城市区的煤矿塌陷土地所表现出的生态破坏又千差万别。本文对上述不同地区煤矿塌陷区和露天采矿区的生态重建战略问题分别进行了论述。

There are many ecological destruction problems in coaleconomy cities,such as large areas of land subsidence and water pollution during the process of underground or surface coal exploitation.These ecological destructtion problems vary in different areas of desert,loess planteau,north plane and rainy south.This article discusses the ecological reconstruction strategy of the land subsidence caused by coal exploitation and the areas of surface mining.
