STRUCTURAL OPTIMIZATION OF JIANGSU'S CHEMICAL INDUSTRY CONSTRAINED BY CARBON REDUCTION AND WATER ECOLOGICAL CARRYING CAPACITY
Yangtze River economic zone,as China's key strategic zone,is closely related to national development by its ecological restoration and resources use.Jiangsu's chemical industry,an intensive polluting and resources-depleting industry,needs to properly handle industrial development and resources & environmental protection,which is of significance to protect Yangtze River and realize carbon reduction.This paper establishes a multiple-objective optimization model of chemical industry under dual constraints of carbon reduction and water ecological carrying capacity,and applies NSGA-Ⅱ-VIKOR algorithm to discuss the way to adjust Jiangsu's chemical industrial structure.Balanced development scenario,compared with low-carbon,water-saving and economic development scenarios,can save water of 998.48 × 104 m3,reduce carbon emission intensity by 4.27％,and make GDP rising rate up to 4.73％on the basis of benchmark year 2017.Water resources are used efficiently and carbon emission is largely reduced,while economy gains high-quality development.Chemical industrial structure needs to be adjusted through developing rubber and plastics,limiting petroleum processing,coking coal and nuclear fuel processing,using water-saving and carbon-reducing measures in chemical fiber manufacturing.Optimization of chemical industry needs to promote clean energy and reform energy consuming structure,with coal use down by 5.54％and gas & electricity use up by 5.45％.Water resources allocation should be consistent with industrial structural adjustment,which can save water by 9.8％in petroleum processing,coking coal and nuclear fuel processing,and 5.14％in chemical fiber manufacturing,which can be transferred to rubber and plastics sector.This paper presents suggestions on increasing regional ecological carrying capacity to realize high-quality development,establishing clean energy consuming system to raise energy efficiency,developing water-saving industries to materialize a coordinated sustainability in industrial development and water ecology.
