摘要: 露天矿生态承载力的变化与矿区的污染控制、土地复垦与生态重建措施密切相关。本文根据矿区生态承载力内涵及层次特点, 从生态系统弹性力、资源环境承载力及生态系统压力度3个方面提出对其进行量化的研究方法。结合高吉喜提出的生态承载力评价方法, 构建了较完整的评价指标体系, 利用AHP法求得各指标权重值, 对矿区生态承载力状况进行静态和动态评价。研究结果表明: 平朔安太堡矿区2007年的生态系统弹性力为46.836, 中等稳定; 资源环境承载力47.127, 中等承载; 生态系统压力度为1.396, 承载超负荷。从动态变化趋势看, 平朔安太堡矿区生态系统弹性力波动较强烈, 说明矿区生态系统稳定性差, 具有明显的脆弱特性; 生态系统压力指数的变化说明, 1999年前生态系统的压力对矿区生态系统弹性力和资源环境承载力影响较大, 而1999年后影响逐渐减弱, 矿区1987~2007年生态系统弹性力和资源环境承载力变化趋势相同; 1997年后生态弹性力开始上升, 资源环境承载力在1999年后也处于明显上升趋势。 |

Abstract: Change in Ecological Carrying Capacity (ECC) in open coal mines is closely related with pollution control, land reclamation and ecology rehabilitation measures. Based on connotation and hierarchical characteristics of ecological carrying capabilities of mines (MAECC), a quantified assessment method of MAECC involving ecosystem resilience, resource and environment carrying capacity, and ecosystem stress is put forward. The unified ecological carrying capacity appraisal method proposed by Gao Jixi, combined with an established index assessment system with the index weight decided by AHP, was used for static and dynamic appraisal of the MAECC. The ecosystem resilience of Antaibao Opencast Mine ecosystem in Pingshuo is 46.836 for 2007 - which is described as moderately stable. Environment carrying capability is 47.127 - which is medium load bearing. The ecosystem stress is 1.396 - which is excess load bearing. Based on the change dynamics, there is a drastic change in ecosystem resilience. This shows that the stability of the ecosystem in mining areas is weak with obvious frail characteristics. The change in ecosystem stress index implies a greater impact of ecosystem stress on the resilience of the ecosystem and the carrying capacity of mine area resource and environ-ment before 1999. This impact has gradually weakened since 1999. This conclusion is also true for the trend of ecosystem resilience, resource and environment carrying capacity of mining area for 1987~2007. The resilience of the ecosystem began rising after 1997 along with a significant increase in the carrying capacity of the resources and the environment after 1999. |
