Construction of Regional Industrial Systems Cleaner Production Integrated Evaluation Model and Its Application

摘要

The unit industrial added value energy consumption, unit GDP industrial S02 emissions, unit GDP industrial wastewater emission, unit GDP industrial solid waste yield, industrial system pollution treatment indexes including industrial S02 removal rate, industrial wastewater emission pass rate, industrial solid waste comprehensive utilization rate are selected from two points of view of industrial system pollutant emission and treatment for constructing regional industrial system cleaner production integrated evaluation model. The model was used for demonstration research on cleaner production level of Chongqing industrial system, the system indicated that the cleaning production level of Chongqing industrial system is located in the medium level currently and has greater gap from other municipalities, and it is located in higher level compared with other regions in western part. The cleaner production level of Chongqing industrial system from 1997 to 2009 experienced a process of decreasing firstly and steady increasing later. The year of 1999 is a turning point during the process, and environment policy of the government played an important role in improving the cleaner production level of the industrial system.
