      摘要:以山西省潞安礦區(qū)為研究對象,應(yīng)用AHP綜合評價模型,根據(jù)礦區(qū)生態(tài)承載力理論從生態(tài)系統(tǒng)彈性力、資源環(huán)境承載力及生態(tài)系統(tǒng)壓力度3個方面建立了礦區(qū)生態(tài)承載力量化方法,構(gòu)建礦區(qū)生態(tài)承載力評價指標體系并進行生態(tài)承載力評價。結(jié)果表明,潞安礦區(qū)的生態(tài)系統(tǒng)彈性度為37.31,屬弱穩(wěn)定;資源環(huán)境承載力為48.17,屬中等承載;生態(tài)系統(tǒng)壓力度為55.31,屬中壓狀態(tài)。

      Abstract: Taking Lu’an mining area in Shanxi province as studying object, the quantitative method for assessing the ecosystem carrying capacity was established from the aspects of ecosystem elastic force, resource and environment carrying capacity by comprehensive assessment model, and ecosystem stress based on ecological carrying capacity theory of mining area; assessment index system for ecosystem carrying capacity of mining area was constructed and applied for environment carrying capacity assessment. The results showed that ecosystem elastic force of Lu’an mining area was 37.31, demonstrating weak stability of Lu’an mining area ecosystem; the resources and environment carrying capability was 48.17, indicating medium carrying capability; and ecological stress was 55.31 which was medium level.

      Key words: AHP comprehensive assessment model; ecological carrying capacity; ecosystem elastic force; resources and environment carrying capacity; ecosystem stress; Lu’an mining area
