On The Evaluation Of Natural Capital For Grassland Nature Reserve

The thesis proposes two models of evaluation for natural capital on natural property and social property based on the former research.The evaluation on the value of ecosystem services belongs to the evaluation on natural capital in view of natural property.The purpose of this thesis is to set up an evaluation framework on natural capital composed of two models of evaluation on capital benefit and capital management by integrating the research findings of ecology,economics,sociology and other subjects.The benefit evaluation module on nature capital includes assessments on profit capacity, capital character,capital derivatives and market prospect.The management evaluation module on nature capital focuses on capital investment,capital circulation and capital running.The natural capital evaluation model,based on social property,can fulfill the demands of different stockholders on nature reserve value,economic benefit,ecological compensation calculation,capital circulation and feasibility on investment.The evaluation framework of natural capital,based on social property,is an original creation of this thesis.It's the first time to study the evaluation model of natural capital and apply it in the evaluation on natural capital in nature reserve.The thesis has put forward the concept of"derivatives of natural capital"and studied the derived capacity of natural capital,which is based on derived sources.The derived sources are composed of vegetation landscape,wild plant and life,environmental resources,history,culture,science and technology,international exchanges,and so on.Tourists,local residents and historic figures deduce, hand down and found gorgeous derivatives,including aesthetic feeling towards nature,desire to explore, mood of returning to nature,treasuring of wild plant and life,curiosity to natural landscape,advocating to some spirit,recalling the past,totem,belief,will of payment in nature protection,and so on.The value of derived capacity of natural capital is realized by running the derivatives of natural capital.It's the first time to take Stakeholder theory as a basic theory in evaluation on natural capital.The ways been used include economics,ecology,biology,sociology,and so on.The economics methods are composed of analysis and calculation.The way on value of stocking capacity of grasslands is taken as the way of evaluation on natural capital for the first time for grassland nature reserve.Case studies on natural capital in I.M.XILINGUOLE Grassland National Nature Reserve have been taken by applying the evaluation theory and framework on nature capital.The research findings:1. Evaluation on profit capacity:The value of Inner Mongolia XILINGUOLE National Nature Reserve(IMXNNR) is 660,611,581.2 yuan RMB per year,the price of 5 years tenancy is 3,866,698,737.45 yuan RMB.2.Evaluation of capital character:Through the analysis of time heterogeneity,the capital character of IMXNNR is stable,and compared with the targets in grass yield, the important value of species,stocking capacity of grasslands,carrying capacity per unit area for sheep, and so forth in 1980s,there's no obvious degeneration on grassland.3.Evaluation of capital derivatives: In I.M.XILINGUOLE Grassland National Nature Reserve,derived capacity is achieved mainly through running tourism because of its rich derived source of natural capital,developed derivatives operating and strong derived capacity.In derived source,landscape is the biggest contribution,accounted for 34.7%;the contribution of history and culture resources accounts for 18.4%.This shows that the developed level is lower in the reserve,and the history and culture resources tourism has the potential used at large scale in practice.4.Evaluation of market prospect:There are bright prospects for tourism with the growth rate of 30.15%per year in I.M.XILINGUOLE Grassland National Nature Reserve.It will be expected that 99,451,288.5 yuan RMB per year may be harvested by carbon sequestrating. Changes will not be obvious on farming and animal husbandry in recent years affected heavily by regulation and control.5.Evaluation of capital investment:After studying the implementation of Treatment Project of Sandstorm Sources of Beijing and Tianjin in the reserve,summarize that it needs investment on ecological engineering 1.3 yuan RMB per Mu every year to maintain the status quo of capital quality in I.M.XILINGUOLE Grassland National Nature Reserve.6.Evaluation of capital circulation:The adjusting of function areas and range of I.M.XILINGUOLE Grassland National Nature Reserve makes natural capital in the reserve reduce by 0.4586 million hactares and the ecological compensation calculation is 3.9949 yuan RMB.Requisition compensation standard and specialized foundation for nature reserve are proposed based on case studies.7.Evaluation of capital running:The necessity and feasibility to invest and construct nature reserve has been defined.Capital running can be achieved in the fields of tourism,prataculturae,science and technology extension,green food processing industry,sand industry and modern animal husbandry after study.
