山西省潞安矿区生态恢复模式研究

在对潞安矿区自然经济条件、环境破坏程度和土地利用现状进行调查与分析的基础上,根据潞安矿区实际,以尽快恢复被破坏土地的原有生产力为出发点,以恢复改善生态环境为目标,提出了稳定塌陷区生态恢复模式、潜在或动态塌陷区生态恢复模式、煤矸石山环境治理模式、废弃地生态恢复模式、环境污染区生态恢复模式、家园服务生态恢复模式等6类适合潞安矿区的生态恢复模式,每类模式里又包含几种子模式.经过对矿区不同区域实施的生态恢复模式成效的调查结果表明,该生态恢复模式系统的建立和空间分布格局是科学合理的,符合潞安矿区的实际情况,并取得了良好的经济效益和生态效益.

Eco-environmental Restoration Models in Lu' an Mining Area of Shanxi Province

This study is based on the investigation and analysis of natural and economic conditions and the extent of environmental damages and land use in Lu'an mining area. According to the actual conditions of Lu'an mining area and taking the restoration of original capacity of destroyed land as the starting point,six ecological restoration models suitable to Lu'an mining area are put forward in order to restore and improve the ecological environment. The models are the ecological restoration model of stable subsidence area,the ecological restoration model of dynamic subsidence area,the ecological restoration model of coal gangue field,the ecological restoration model of disused land,the ecological restoration model of environmental pollution region,and the ecological restoration model of homestead service. Each ecological restoration model contains several sub-models. Results from survey indicate that the system of ecological models is scientific and reasonable. Moreover,the high economic and ecological benefits have been obtained in recent years.
