| The industrial production mode of traditional economy is continuing damage to the environment, which deepens the contradictions of human society and the natural environment, while recycling economy is trying to change this kind of production model to ease the contradiction between human society and the natural environment. Some theories such as Cleaner Production and Industrial Ecology have also been proposed because of similar reasons. Based on these theories, this industry in the form of eco-industrial park formed. Eco-Industrial Park is an important way to achieve circular economy, while industry chain is the core of eco-industrial park. Therefore, the study of eco-industrial chain contribute to the stability and sustainable development of eco-industrial park.In this paper,3R principle, the principle of scientific and accurate, feasibility principle comprehensive principle and holistic principle are the principles of constructing the model. Related standards developed by the Ministry of Environmental Protection, related standards developed by Environmental Protection Agency and the actual situation of Vanadium and Titanium industry are standard of constructing the model. On the basis of these principles and standards, industrial chain evaluation index system and evaluation model in eco-industrial park of vanadium and titanium industry were construct. The index system includes economic development, recycling, ecological environment construction, public support, industrial chain emissions, the stability of the industrial chain and industrial chain efficiency. This paper investigated the basic situation of Panzhihua Vanadium and Titanium industrial park’s industrial chain:the park’s main industries is vanadium and titanium industry, machinery manufacturing industriy, supporting chemical industry and nonferrous metals electric smelting industry, so that the park chain is a comprehensive industrial chain, its composition is based on titanium industrial chain, vanadium industrial chain, machinery manufacturing industrial chain and sub-affiliated industry of vanadium and titanium industrial chain, combined with Vein industrial chain. Panzhihua vanadium and titanium industrial park as an example, this paper used the evaluation index system and evaluation model, combining with the relevant data, to evaluate the industrial chain. This paper make a conclusion of that the status of industrial chain in Panzhihua vanadium and titanium industrial park is good. According to the results, this paper gave some to suggestion on economic development, recycling, ecological environment construction, public support, industrial chain emissions, the stability of the industrial chain and industrial chain efficiency. |
