| 中文摘要 | 以磷元素为例,运用物质流分析方法建立了2000年全国水平上的静态磷物质流分析模型(PHOSFLOW),并对中国磷循环系统的结构特征与物质利用效率特征进行了系统识别.结果表明,2000年中国磷的总物质需求量达到815.9万t,经过社会经济系统代谢后输出到国内环境的磷物质量为744.6万t,其中进入水体磷负荷107.5万t,由于磷的生产和消费部门的磷物质利用效率水平较低,中国磷循环系统在整体上呈较为典型的单向、开放式物质流结构.; By applying substance flow analysis (SFA) approach, a static SFA model for national phosphorous cycles of China in 2000 (PHOSFLOW) was constructed. Based on this model, both aggregated physical characteristics and sectoral material use efficiencies were subsequently analyzed. The total material requirement (TMR) of phosphorus in China reached 8159 kilotons in 2000. The amount of 7446 kilotons was ‘excreted’ to domestic environments via societal metabolism, in which 1075 kilotons phosphorus terminated in the sink of surface waters eventually. The Chinese phosphorus cycle system showed as a one-way and open-looped physical structure, due to the low levels of overall and sectoral material use efficiencies.; 高等学校优秀青年教师教学科研奖励计划 |
