摘　　要：利用物质流分析方法,对2000～2007年成都市环境经济系统中物质输入与输出进行分析,结果表明:(1)在不考虑水的情况下,成都市物质输入与输出总量呈相似的增长趋势,但物质库存量有净增长;固体物质输入量的递增速率大于气体物质输入量的递增速率,物质输出量气体占主体;(2)物质输入与输出强度不断增加,而单位GDP物质输入量与输出量呈快速递减趋势,物质生产力不断上升,表明成都的资源综合利用效率明显提高,区域经济增长和环境压力正在逐步脱钩;(3)水的输入输出量呈上升趋势,但是其强度基本保持不变,用水效率稳步提高。The economy and ecological aspects of a social system are coherently linked and can be examined by its material and energy flows.Dynamic analysis was carried out from material flow analysis（MFA） on material inputs and outputs between the economy and the resources of Chengdu City from 2000 to 2007.It can be concluded that：1） excluding water,the total material inputs and outputs showed similar increasing trend,but the material inventory showed net growth;the increasing rate of solid materials inputs was higher than that of gaseous materials;the gas outputs counted the largest portion of the output;2） the intensity of material inputs and outputs increased persistently,the material inputs and outputs per unit GDP showed rapid decreasing trend,and the material productivity rose persistently,namely the comprehensive utilization efficiency of resource in Chengdu City has been accelerated as the economic and environmental changes are tightly coupled;3） the total water inputs and outputs showed increasing trend,but the intensity was almost invariant;the water use efficiency has steadily increased.
