The Value Evaluiation Of Rare Earth Resources In Ecological Environment Compensation Mechanism

With the development of the global economy,Mineral resources that are increasly demanded by the global countries has played an important role to the development of national economy.Along with the increase of demanded for rare earths,We intensified the efforts on exploitation of rare earth resources are exhausted,At the same time it also make seriously damage to the source of the ecological environment.In the past,The methods of evaluating rare earth resources value also had considered the damage to environmental,But they were in the form of environmental management and ecological restoration margin calculation,Without outstanding ecological environment destroy to the value of rare earth resources,Rare earth resources exploitation in bear no ecological compensation for the vegetation restoration waste water treatment,Crop losses and vegetation decrease oxygen loss under the situation of expenses will not attach importance to environmental protection,So it is not conducive to the ecological compensation mechanism in the assessment of rare earth resources value in order to promote the healthy development of rare earth industry protect ecological environment,Realize the sustainable development of economic and social,Control of rare earth resources mining in reasonable way in our country.In this paper it is focused on considering the compensation mechanism of ecological environment basis to evaluate the value of the earth resources,With the aid of yao xia of gan zhou under mine rare earths for this paper.By constructing ecological compensation mechanism of rare earth resources value evaluation model,through the model,It can be scientific and rational a rare earths mine true value.Its rare earth resources value evaluation resulta will be on the high side,Without introducing ecological compensation mechanism to estimate the value the rare earth resources,So it will not reflect a true of rare earth resources mining area.The research mainly includes three aspects of content,absorbed for rare earth resources value evaluation research results both at home and abroad,Combined with more and more attention to the protection of the ecological environment situation to evaluation its value in the new study.First of all,It points out that the rare earth resources evaluation principle the value of ecological environment compensation connotation definition and related problems with systematically expounding the value of rare earth resources and the basic theory of ecological compensation mechanism.Secondly,It has explored and summarized several mainstream evaluationmethod with its corresponding model,Introduced ecological compensation mechanism,The established a reasonable rare earth resources value evaluation model on the basis of the existing model,Finally,It is concluded that the true value of rare earths in the region a typical YaoXia,GanZhou mine as a case.It compensates value of rare earth resources value evaluation research to a certain extent and improve the system of evaluation theory based on ecological.In order to further enhance the operability of the model,This article does not carried out on the sample data of selected considering with the influential factors of currency inflation as a result of the assessment of discount rate is difficult to determine It still have limitations of this study,The ecological environment under the compensation mechanism of rare earth resource value evaluation model to assess value in the process of rare earth resources.In this article,On the other hand,The data is difficult to obtain some indicators,The data acquisition are greatly influenced by subjective factors when calculating the ecological environment compensation thus causing a slight deviation evaluation results.In the later research,Subjective influence,Some modified for exploration,Minimize subjective factors and the influence of the time value of money factors,Making the assessment of rare earth resources more accurate results.
