Study On Ecological Restoration And Landscape Regeneration Of Lead And Zinc Mining Areas In Urban Double Repair

The lead-zinc deposit of Lanping is one of the world’s third largest pb-zn deposit,the history of local mining smelting minerals is a long time,but the real large-scale development is at the beginning of the country after the reform and opening-up policy,the large-scale development of lead-zinc mineral resources,which can help the development of regional social economy also consumed a lot of mineral resources at the same time,also associated a large amount of waste pollution at the same time,on the regional ecological environment caused great damage and influence.Nowadays,the problems of ecological environment pollution and landscape fragmentation in mining areas are particularly prominent in the reuse of mining development sites,which must be taken seriously and effectively solved.The development requirements of modern cities are no longer limited to the increase of quantity,but pay more attention to the improvement of quality.Abandoned mining land languish rate is high,like the scars of the earth grows in the urban environment,recycling has certain difficulty and risk,and the urban development tend to take easy to difficult,with the development of the whole city and updated tends to saturation,the existence of the abandoned mining land and urban development will become increasingly stand out,the contradiction between the paradox contains two aspects,one is abandoned mining area land and the contradiction between urban development and the ecological request good,the second is the mining area inefficient land use.Based on the concept of "city double fix" for ecological restoration and landscape regeneration of abandoned mining area land is a key to solve the above contradictions,In this thesis,based on the actual situation of the damage caused by pollution in the lead-zinc mining area of lanping,and combined with the renewal demand of lanping as a mining town,the ecological restoration strategy and landscape regeneration model of the lead-zinc mine were studied,then discusses the ecological restoration and landscape regeneration of small mining towns from the perspective of " city double fix ".Starting from the theoretical requirements of " city double fix" on ecological restoration and landscape regeneration in mining areas,the thesis introduces the natural environmental conditions,cultural and social situation,development course of mining industry,pollution and damage situation of the mine area and the existing treatment measures in the lanping lead-zinc mine area,discusses the existing ecological restoration technology can be used for lead and zinc mine,according to the characteristics of landscape elements and pollution damage severity of abandoned mine land site classification,site build all kinds of ecological restoration model,sums up the suitable for the two landscape regeneration utilization patterns of Lanping lead-zinc mine area,points above two kinds of recycled mode of various types of landscape space landscape regeneration Suggestions,in order to provide some reference for the ecological restoration and landscape regeneration of the Lanping lead-zinc mine area and similar mine area.
