摘要
矿产开发对土壤环境的影响日益受到重视。本文选取典型的矿业城市——贵州省六盘水市,在分析煤炭资源开发对土壤环境的不利影响的基础上,认为各种不利影响可以归纳为两类:占地损失,为不可逆影响;土壤肥力损失,为可逆影响。并提出可以用机会成本法和恢复费用法对两类影响分别进行评估。文章最后阐述了减缓煤炭资源开发对土壤环境影响的基本措施。
People are taking soil environment influence of mineral exploitation more and more seriously. Liupanshui city is a typical mining city. Coal exploitation exerts negative influence on soil environment: soil quantity loss and soil fertility loss. The former is irreversible, while the latter is reversible. Opportunity cost and resuming expenses are respectively suitable to evaluate above-mentioned types of influence.
