陕西省乾县五峰山石灰岩矿高效利用与生态修复研究

Research on the efficient utilization and ecological restoration of Wufeng mountain limestone minerals in Qian county,Shaanxi province

陕西省乾县五峰山地区赋存丰富的石灰岩矿产资源,近20年来,随着社会经济的高速发展,该地区石灰岩矿产资源被大规模开发,粗放式的开发造成了资源严重浪费,高强度的开采导致矿区环境恶化。本文对矿产资源开发过程中存在的资源问题和环境问题进行了系统总结,在此基础上,以解决开发利用过程中存在的资源问题、环境问题为导向,通过矿产资源集中开发、分级利用、综合利用提高矿产资源利用水平;以师法自然,重建"山水林田湖草生命共同体"的理念,通过地形重塑、水土保持综合治理、植被系统重建对矿区生态修复进行探讨,旨在破解矿产资源开发与环境保护的矛盾,实现资源效益与生态效益的协调统一。

There are abundant limestone mineral resources in the Wufeng mountain area of Qian county,Shaanxi province.In recent 20 years,limestone mineral resources have been exploited on a large scale with the rapid development of the social economy.Extensive development has led to a serious waste of mineral resources,and high-intensity exploitation has resulted in the deterioration of the geological environment in the mineral area.This paper systematically summarizes the problems of resources and environment in the process of mineral resource development.In order to solve the resource problems and ecological problems existing in the development and utilization,the utilization level of mineral resources should be improved through intensive utilization,graded utilization,and comprehensive utilization.The paper discusses the ecological restoration of the mineral area through the reconstruction of topography,comprehensive management of soil and water conservation,and reconstruction of biological community based on the concept of learning from nature and reconstructing the life community of mountains,rivers,forests,farmland,lakes and grasses.It aims to solve the contradiction between mineral resource development and environmental protection and realize the coordination and unification of resource and ecological benefits.
