青藏高原矿产资源开发的环境适宜性评价——以西藏达孜—工布江达地区为例

Environment suitability of mineral resources development over Tibetan Plateau:A case study of Dazi-Gongbo’Gyamda,Tibet

摘要: 为保障青藏高原矿产资源的科学开发及其与环境保护的协调发展,以西藏达孜—工布江达地区为例,对青藏高原矿产资源开发的环境适宜性评价方法做了研究。首先优选出研究区的矿产资源接续基地,接着从生态脆弱性和地质灾害危险性两方面对资源接续基地进行矿产开发活动的环境适宜性评价。采用专家打分-层次分析法计算指标权重并用综合指数模型进行定量评价。评价结果表明:本文建立的评价方法是可行的;研究区的矿产资源接续基地总体上可以进行开发,但存在野生动物保护区、宗教圣地、国道沿线等少数区域不适合开展矿产开发活动;矿产资源接续基地的不同矿区,矿产开发的环境适宜程度有所差异。评价结果可为研究区矿产资源的有序开发和生态环境保护提供依据。

Abstract: To guarantee the sustainable development of mineral resources exploitation and environment protection over tibetan plateau,taking Dazi-gongbo’gyamda,Tibet as an example,environment suitability for mineral resources development in plateau was studied.Successive mineral resources base of the study area was selected on the base of environment,then the environment suitability of successive mineral resources base was made from two parts: ecological fragility and geological hazard risk.The expert scor...
