中文摘要：
通过区域系统物质代谢的方法研究了江苏省食物、能量、水、物质和废弃物的输入与输出。在研究期限内．固体废弃物输出的增长率高于固体物质输入增长率；废气排放的增长率高于化石燃料输入的增长率；废水输出的增长率低于淡水输入的增长率。各种物质输出与输入总量之间存在着正相关关系。江苏省区域代谢的趋势是上升的，尽管各种物质与能量的利用效率提高了，但是还不足以降低其对陆地、水体和大气环境的压力。通过建立物系管理体系、物质投入减量化等方法可降低区域代谢的脆弱性，提高代谢效率。
英文摘要：
The overall flues of food, energy, water, material and wastes into and out of the Greater Jiangsu Area were studied quantifieationally using material metabolism method. The most noticeable feature showed that outputs of solid wastes had generally increased at higher rates than inputs of solid material. Outputs of air emissions had generally increased at higher rates than inputs of fossil energy. Outputs of wastewater had generally increased at lower rates than inputs of fresh water. There was a positive correlation between outputs and inputs. The speed of the metabolism was higher and higher. The trends of material metabolism were escalating. Although all kinds of materials and energy had been used more efficiently, the ecological press on land, waters and atmosphere environment had not been reduced. Some pieces of policy advice also were given in this paper.
