Resaerch About The Impact On Ecological Environment And Ecological Restoration Technology Of Yaogangxian Tungsten Mining In Chenzhou

Our country is the largest country of tungsten ore reserves, tungsten is the advantage of mineral resources, China’s tungsten ore mining over the years for the development of the world’s tungsten products provide a lot of material, but with the dwindling resources of tungsten, China’s tungsten ore reserves advantage is slowly disappearing. The waste of resources of tungsten ore mining and processing of mineral industry in addition to affecting the outer part of our tungsten mining or roughing the parts of the pillar industries has caused serious ecological damage, especially of quartz vein type wolframite mainly caused by the formation of the characteristics of such deposits in quartz vein wolframite is easy to choose and easy pick, so our quartz vein type wolframite to develop early "yield more" big-scale and famous, many of wolframite After years of exploitation, waste of resources and ecological destruction problems faced also particularly prominent and 严峻瑶 Kong cents as well as skarn scheelite deposit, this paper analyzes the YiZhangXian Yaogangxian tungsten ore in the process of ecological restoration The problem, in conjunction with the subject knowledge, analyze and learn from outstanding cases at home and abroad, aimed at resolving the YiZhangXian Yaogangxian wolframite landscape ecological destruction and waste of resources and other issues, Chenzhou City, tungsten ore and girls near ecological restoration proposed feasibility He suggested that article the main results are as follows:(1) Tungsten is currently used on a very wide range of the world’s non-ferrous metal resources, the exploitation of mineral resources of tungsten on the ecological environment has caused serious damage, but there is a great lack of research of ecological environment in mining pollution.(2) Chenzhou City, is a mineral resource extraction is the main economic pillars of the city, mining the ecological environment has caused a serious negative impact on the tungsten mining pollution and contamination complicated reasons, over time, a larger repair of difficulty, in this paper, ecological landscape planning to use the ecological reconstruction of tungsten ore, combined with modern urban planning theory and landscaping aesthetics ideas and put forward were restored for the physical, chemical, biological and engineering of contaminated land, water, vegetation and other resources measures.(3) in the field survey, we found that tungsten ore Yaogangxian current ecological problems and serious, has a direct impact on local people’s production and life, but local residents to protect the ecological environment and the recovery is still less understand, ecological restoration relatively low level of economic development mode single ecological restoration Yaogangxian itself based on topography, the distribution of resources and historical and cultural characteristics of the Yaogangxian divided into a central area, two landscape belts and four functional areas, namely tungsten is Yaogangxian experience Center, Swan ecological landscape with mountain and river scenery with policy, mining ruins landscapes, agriculture and leisure tourism, ecological restoration areas and ecological farming area, they were different for different ecological regions landscape restoration and reconstruction means, select the appropriate vegetation, in order to promote the transformation of ecological restoration and economic development of the Yaogangxian tungsten ore.
