Research On Evaluation System Of The Value Of Mining Waste Reclamation

The report proposed to the party’s18"ecological civilization" Included into the construction of socialism with Chinese characteristics "five in one" the overall composition. Land reclamation is the implementation of the "18" to speed up the construction of ecological civilization,the strictest arable land protection system, the system of economical and intensive land use of important measures, to increase the social value of land use, economic value and ecological value have very important practical significance. Industrial and mining land reclamation is an important part of land reclamation, which establishing a scientific, rational industrial and mining land reclamation value evaluation system is the significant basis for developing the reclamation work and guarantee.The article follows the route of theoretical-demonstration-proposal. The first, generalized the concept of industrial and mining land in theory, summarized the related theories of value evaluation reclamation of industrial and mining lands. According to the present situation of industrial and the value of restriction factors of mining land reclamation, exploring the necessity of the value of industrial and mining land reclamation. On this basis, from the social value, economic value and ecological value of the three angles to find the optimal evaluation index, selecting a reasonable evaluation method, and then builds a system of industrial and mining land reclamation value evaluation, for industrial and mining land work provide certain reference and reference on la,ter period. In the process of empirical analysis, taking Taiyuan city as an example, through collecting and sorting data, constructing the principal component analysis model for empirical analysis. Through the research of empirical analysis in this paper, the following conclusions:The impact factor of industrial and mining land reclamation social value evaluation, residents demand relevance as a whole achieve [0.941,0.907], reclamation factors affect in [0.620,0.695] interval, the main conditions to of reclamation achieve [0.616,0.698] interval, agricultural products and arable land close to [0.705,0.730] interval, the social value evaluation of industrial and mining land reclamation to the rationalization.The impact factor of industrial and mining land reclamation economic value evaluation, will be able to get traffic facilities to improve the degree of municipal engineering construction projects, environmental protection public welfare project and foundation of people’s livelihood project is industrial and mining land reclamation economic value evaluation is the most important influence factors, the effect of0.964, the foundation of the people’s livelihood project effect is0.818; In addition, the agricultural production factors of the effect is more significant, Labor saving effect is reached0.949, can make the influence degree of the industrial and mining land reclamation economic value to achieve the optimal limit.The impact factor of industrial and mining land reclamation ecological value evaluation, restore ecological balance index [0.807,0.938] interval, regulating climate ecological index in [0.715,0.736] interval, protect biodiversity value reached0.850, can make the influence degree of the industrial and mining land reclamation ecological value to achieve the optimal limit.Finally, in the value evaluation of industrial and mining land reclamation, economic value> ecological value> social value. Taiyuan city continuous development of society and economy at the same time, pay more attention to the construction of ecological civilization, comply with the national overall development. In industrial and mining land reclamation value evaluation, and at the same time attaches great importance to the economic, social and ecological value.
