区域物质流规模结构分析评价方法及应用研究

生态经济体系中环境的引导和调控作用是经济系统物质代谢的重要组成部分.为了更为完善地分析评价经济发展和环境压力的关系,在输入端、输出端物质流规模和结构分析中侧重于物质隐藏流的综合计算,并以广州市南沙区为例进行实证研究.研究结果表明:南沙区域出口与出口物质隐藏流呈逐步上升趋势;南沙区的区内生产过程排放呈现"先降后增、总体递增"的趋势,今后南沙区应加强对工业生产过程中工业固废和二氧化硫排放的监控.

Evaluation and Application of Scale and Structure Analysis of Regional

To reflect the guidance and regulation of environment in ecological economic system is an important part of eco-nomic system metabolism. In order to better analyze and evaluate the relationship between economic development and environmen-tal pressure, it base on the scale and structure analysis of input and output substance flow and focuses on the comprehensive calcu-lation of material hidden flow, as a case study of Nansha District for empirical research. Results show that regional exports and ex-port material hidden flow have been gradually risen, and the production process emissions of Nansha District presents a trend of decreasing first and then rising, with overall increasing. It is suggested that Nansha District should strengthen the monitoring of in-dustrial solid waste and sulfur dioxide emissions in the process of industrial production in the future.
