摘要
在明确矿区生态承载力概念的基础上,从生态系统弹性力、资源环境承载力及生态系统压力三个方面建立了生态脆弱矿区生态承载力评价指标体系及其量化方法。并以榆神矿区为例,对其生态承载力现状进行了计算和分析。结果表明,2004年榆神矿区生态系统承载力分级为"不稳定、中等承载、中压",说明本区生态系统比较脆弱,容易遭受外界干扰而使生态系统破坏,同时自我恢复能力也比较低。其中:水文和植被是制约矿区生态系统主要的自然因素;矿区资源和环境具有一定的承载能力,但水资源和大气环境现实承载力较小;资源-环境压力主要来自土地资源压力和水资源压力。并结合计算结果,从矿区可持续发展战略的角度出发,提出增强矿区可持续发展能力的建议。
On the basis of redefining the conception of Ecologic al Carrying capacity （ECC） in coal mining area, the index systems and quantitative method for ECC in ecologically fragile coal mining area were put forward including ecological elastic capacity, resources and environment carrying capacity and ecosystem pressure. The situation of ECC in yushen mining area is calculated and analyzed, the results are that ECC of yushen mining area in 2004 belongs to ＂the instable, medium to carrying and strong pressing district＂, and the ecosystem is more than frail. The primarily restricted factor to ecosystem is hydrology and vegetation. Resource and environment of yushen mining area attribute to medium to carrying. The strong pressing districted resource is land and water. The measures were put forward to mining area in boosting up sustainable development.
