Research On Landscape And Ecology Restoration Of Wasted Ionic Rare Earth Deposit In South China

With the development of industrialization and urbanization in China, the rare earth mining industry is also prosperously developing. Because of the rare earth prices rising in recent years,it further stimulates the mining of rare earths and results in the rare earth ore’s overexploitation.lt finally makes much rare earth mineral resource exhaustion,and it results in a large number of wasted rare earth depositon. However,the rare earth mining overexploitation causes many ecological environment problems in the wasted rare earth deposit.So the paper under this context, discussing wasted ionic rare earth deposit in south china about ecological restoration of abandoned land management, landscape construction and tourism development model.This paper selects the most representative of ganzhou xinfeng, longnan and changting cewu, hetian to make on-the-spot investigation, summarizing four places’s successful governance modes,which are Xinfeng builds navel orange orchard in the waste ionic rare earth land, the longnan’s "pig-gas-vegetable (fruit)" circulation of ecological agriculture model and " changting experience" which introduction the company to develop gingko seedling base, waxberry orchard, the government investment in governance, subsidies laid-off workers in abandoned land of governance and building cooperation with university scientific research.What the similarity of these motheds and modes is they take ecological restoration and regional industry development of waste land with combination,and developing the primary industry,changing the model which just relying on the government’s input and they are the sustainable governance model.Relying on successful governance model which talks above, on the basis of ecological orchard first industry, this paper puts forward land relying on tourism development model of ecological agriculture, and what’s more the ecological environment and landscape of wastelands in rare earth condition directly related to the effects and level of tourism development, and it plays a positive role in promoting the tourism, this paper aims to study the landscape and ecological recovery of waste ionic rare earth lands, and combining with the landscape ecological restoration, researching the innovation of the tourism industry development mode, and example verification.This paper consists of7chapters.Chapter1, mainly talks about the background of south ionic rare earth land management, summarizes the research status at home and abroad, studies the famous successful cases at home and abroad, identified in this paper, the research objectives, research contents, research methods and technical route; Chapter2, making clear the concept and characteristics of the wasted ionic rare earth deposit in south China,and summarizing the related restoration theory of the wasted ionic rare earth deposit in south China. Chapter3, surveying and summarizing the main problems of abandoned lands of southern ionic rare earth, and from the principles of landscape ecological restoration target, the approach to restore the transformation pattern and guarantee mechanism, technical measures and restore several aspects put forward the south the management strategies of ionic type rare earth’s landscape ecological restoration.Chapter4, taking Yangmeikeng wasted rare earth ore area landscape ecological restoration in Changting County of Fujian Province as an example, make master planning of landscape ecological restoration,put forward opinion and suggestion, and making specific cases and theoretical analysis for actual test and verify.Chapter5, conclusion and prospection.Through the research, this paper comes to three conclusions:(1)Summarizing the progress of Landscape and Ecology Restoration of the south ionic rare earth land. making summary of the theory research, technology research, practical research and the development of laws and regulations; Induction and summary the relevant concepts of wastelands of south ionic rare earth, types,and characteristics clearing the basic theory of south ionic rare earth landscape ecological restoration. (2) Combining with previous studies and throughing field survey, and adopting ocular estimation and summarized research, selects suitable plants kinds for the southern ionic rare earth ecological restoration,26species of arbor plants such as pinus massoniana, schima superba, and eucalyptus;22species of shrub plants such as lespedeza, pubescent Holly root;21species of herbage such as sweet clover, the broad leaf finches tares, dicranopteris dichotoma and other.(3) Proposed JunCao technology as the prospects technology mode of rare earth land ecological reclamation, changing previons the one-way input ecological management, the JunCao technology as a kind of sustainable development, can drive the development of rural production pattern of ecological management.(4) On the landscape construction of wastelands in southern ionic rare earth, from the special terrain and upgrading, waste utilization, the water landscape construction three aspects proposed the concrete planning and design method of measures.(5) Putting forward innovation modes of the development of tourism in waste southern ionic rare earth lands,first is by extracting rare earth mining spirit, from rare earth mining relics show,building rare earth ore mining museum and rare earth ore mining parks, rare earth ore mining water and soil science park as tourism development direction,Second is developing tourism agriculture based on a land ecological orchard which builded on the waste land,and developing ecological sightseeing picking, farming experience as the ecological and experience tourism mode;third is developing mountain sports tourism mode which carried out according to land terrain characteristics such as rock climbing, orienteering, outdoor expansion and mountain biking;Fourth is rural leisure vacation travel patterns which based on the farmer’s house, and so on rural folk culture development of.(6) From a solid surface engineering technology, engineering, soil vegetation ecological complex green engineering technology is proposed for the south ionic rare earth landscape ecological restoration engineering measures.(7) Taking landscape and ecology restoration strategy of wasted ionic rare earth deposit in south China as a guide, and puting forward feasible measures to Changtingyangmeikeng wasted rare earth landscape ecological restoration, providing the reference for the subsequent restoration.
