基于SD的煤炭礦區(qū)循環(huán)經(jīng)濟(jì)系統(tǒng)評(píng)價(jià)研究
[Abstract]:At present, China's rapid economic development, agricultural modernization, urbanization, industrialization process continues to advance, the demand for resources, energy continues to increase. Economy, promoting energy conservation and emission reduction, speeding up the transformation of economic development mode is an important strategic decision of our country at present, which is of great significance to the realization of sustainable development of the whole society.
Coal industry is the pillar industry of China's economic development, the basic industry, the development of coal industry circular economy is an important part of building a circular industrial system, this paper based on the theory of circular economy, system theory, from a systematic point of view of circular economy in mining areas to explore and analyze the development of practical significance.
This paper systematically expounds the theory of circular economy, applies the theory of circular economy to the development of circular economy in coal mining areas, analyzes the research status of circular economy in mining areas at home and abroad, and draws three kinds of definitions of circular economy in mining areas: (1) According to the "3R" principle of circular economy theory, constructs the feedback loop of recycling resources and products. (3) According to the eco-economic theory, the circular economy in mining area is essentially an eco-economy. From the angle of system theory, the connotation of circular economy in coal mining area and coal mining area is further studied. Considering the actual situation of coal mining area, the composition, characteristics and functions of circular economy system in coal mining area are studied in detail, and the structure system of circular economy system in coal mining area is constructed, which enriches the theory of circular economy system in coal mining area.
This paper expounds the theory of system dynamics, introduces the basic steps of system dynamics modeling and the use method of Vensim-PLE software. According to the connotation of mining area circular economy system, the purpose of modeling is clarified, the practical problems to be solved and the boundary of the system are defined, its SD simulation and evaluation model are constructed, and the process of validation of the model is elaborated in detail. Taking Longkou mining area as an example, the validity of the model is tested and the empirical research is carried out. The current economic development situation of Longkou mining area is simulated, the main parameters of the model are adjusted and controlled, the rapid development plan and the coordinated development plan of the mining area are designed. It provides realistic basis for achieving sustainable development.
