摘　　要：矿产资源开发利用是国民经济的一项基础产业,具有基础性、原生性、公共性和不可替代性等特点。西部矿产资源在空间分布及开发活动中多与水电资源、农牧资源、旅游资源、林业资源等存在交叉与重叠,导致同一环境本底的不同资源开发的多重、链接作用,由此加重了环境负担,影响了资源的可持续利用,部分矿区已出现较严重的地质生态环境问题,频发的地质灾害已成为地质生态环境质量剧变的前兆。因此需要在西部生态脆弱的矿产资源开发区探索以人类活动规模、强度和效应等为一体的地质生态环境承载力。论文在地质生态环境承载力的研究框架、评价体系、模型与方法、关键应用等方面进行了广泛探讨。The exploitation and utilization of mineral resources with basic,native,public and non-substitutable characteristics are a basic industry of the national economy.The distribution and exploitation of mineral resources often cross and overlap with water resources,agricultural and animal husbandry resources,tourism resources,and forest resources.This spatial feature leads to comprehensive,cumulative action between different mining activities in the same environmental background,which increases the burden on the environment and influences the sustainable development of resources;there were some serious geo-ecological problems in some mining areas such as frequent geological disasters.Thus,it is necessary to discuss the geo-ecological carrying capacity in combination with the scale,intensity and effect of human activities in the ecologically fragile mining area in western regions.This paper made a wide range of discussion on research frame,assessment system,model,methodology and key application.
