| Since the reform and opening up, not only national economy keep the sustained, rapid and steady development,but also the goal of establish a modern market economy system has made a great progress, and to all aspects of social life brought many significant and profound changes. In planning, from the past, seeking pure economic targets transformed to economic, social and natural comprehensive, coordinated and sustainable development,and more and more attention in environmental factors of the economic development. It is can be fully reflected in the party and the state in recent years, a series of line, principles and policies. As 16th CPC big reports said that will promote the harmony of human and nature, and promote the whole society to develop production, affluent life and sound ecological civilization,and 17th explicitly proposed "people-oriented, overall, coordinated and sustainable scientific development", In China's future economic and social development blueprint, the improvement of ecological environment, as an important goal in social and economic development.On November 8th,2006 the ministry of land and resources on issued the second round of mineral resources planning work", Soon issued The second round of mineral resources overall planning of provincial level, The second round of mineral resources planning environmental impact assessment for the first time included, definite requirement of mineral resources planning environmental impact assessment。To further clarify the importance of planning environmental impact assessment, October 2009 1 was promulgated by the state Planning environmental impact assessment ordinance, One more specific planning environmental impact assessment and examination method and the legal responsibility.The development and utilization of mineral resources in the national social development plays a very important role in the rapid economic development and demand of mineral resources more nervous, under the background of the correct dealing with good mineral resources exploration, development and utilization of environmental protection and the relation between the requirements increasingly urgent. Our country mining industry development is in a responsibility for social and economic development and environmental resources shortage facing the dilemma. To ensure implementation of mineral resources planning, environmental sustainability of resource is one of the most effective methods of mineral resources planning environmental impact assessment.At present, environmental assessment of mineral resources plan in theory and empirical research exists hysteresis at the initial stage, not yet formed a mature theory and method system. In the current study, the main focus on the environmental impact of unilateral mine ecological research, not from a broader more integrated approach to the real use from the perspective of sustainable development, very little research, because of extensive mineral resources planning, in addition to ecological impacts other than the entry point of impact is difficult to find, research target selection difficult, more difficult to quantify. The reality requires the combined effects of mineral resources planning must also have knowledge, combined with a comprehensive environmental impact assessment of science and conduct research in this area is imperative.From home and abroad, strategic environmental impact assessment study and practice can be seen that the application of environmental impact assessment been great popularity and development. Environmental Impact Assessment in China started late, especially mineral resources planning environmental impact assessment. Environmental impact assessment of mineral resources planning in the areas include:①the socio-economic development of mineral resources on the support;②the impact of mining on the social development;③the impact of mining on economic development;④mineral resources development and utilization of environmental impact, the main theoretical basis have the resources to environmental economics, sustainable development theory and the theory of circular economy.Mineral Resource Planning Environmental Impact Assessment in compliance with mineral resources-natural-economic and social environment of the system law, the indicator system is divided into four levels. The degree of regional sustainable development as the starting point and final evaluation of the end-result, and based on the evaluation scores of different mineral resources into planning and reasonable, the basic rational planning of mineral resources, mineral resources planning three conclusions unreasonable. Sustainable development through the system stability level of development, coordination, and to reflect the level of degree, of which the stability of the social stability, economic growth, investment in infrastructure to reflect; coordinated by the resource utilization efficiency, the natural ecological harmony, economic and social coordination to reflect; level of degree by the resource potential, pollution control capability, to reflect the economic performance. In the index system to determine the weights, the coordination of the weights of the largest coefficient, focusing on sustainable development reflected the thoughts and ideas.The overall planning of mineral resources in Tongling City in order to follow Tongling city as a national strategy of circular economy pilot basis, to carry out development and utilization of mineral resources distribution and utilization of, efforts to build mining cycle economic model, to carry out Dongguashan ecological and Xinqiao Pyrite Mine comprehensive utilization of mineral resources, demonstration projects, which is planning the development of industrial economy in Tongling City'to a breakthrough in recycling economy, with emphasis on copper, pyrite, limestone resources, establish and improve the three major industrial cycle chain, in accordance with the circular economy "reduction, reuse, recycling, "the principle of resource and energy use to maximize, minimize discharge of pollutants into goals, reform mining pollution of those toxic, parathion chemicals, textiles, building materials four major traditional industries. 'The development and deployment of a large run-in of both mutual promotion and mutual influence, help to promote the development of circular economy in line with Tongling City Development Goals.Tongling mineral resource evaluation and plan between the results between 0.6908-0.8357. Prior to the index system in accordance with the level of division, Tongling City, consistent with sustainable development of mineral resources planning requirements, the planning objectives become more reasonable. Coordination of environmental impact overall higher system development, the coordination coefficient above 0.7 is basic overall coordination, lack of coordination is that environment is not high. Resource conversion efficiency of three indicators of mineral resources comprehensive utilization of mineral resources and mining recovery rate of water circulation rate is high, mainly in Tongling City, as the experimental unit city policy, and the recycling economy Tongling mining economy the focus of cycle. Coordination of environmental evaluation, environmental investment rate is now at the low increase in the planning efforts are still far from the requirements of sustainable development. The rate of land reclamation and ecological restoration of mine average low water governance. Increase in the development process should focus on the ecological environment. |
