【摘要】：从水资源复合系统的角度出发,对复合系统进行能量分析,提出运用能值理论与方法对流域水资源定量分析的思路。论述了能值的基本理论与方法,以太湖流域水系为研究对象,绘制了流域水资源能值系统图,并编制能值分析表,对流域2007—2011年供水水资源的能值转换率进行计算。研究表明:流域水资源能值转换率呈逐年增大趋势,与流域近年为改善流域水环境,加大水环境综合整治及系列工程项目的情况吻合;另外,人工干扰下水资源的能值转换率较天然水资源平均增长24.3%,而且这种增长也呈逐年上升趋势,从2007年的4.31%到2011年的36.4%,说明流域水资源量虽丰富,但安全供水的代价却越来越大。水质型缺水将是20世纪面临的新挑战。
[Abstract]:From the point of view of water resources composite system, the energy analysis of composite system is carried out, and the idea of applying emergy theory and method to quantitative analysis of river basin water resources is put forward, and the basic theory and method of emergy are discussed. Taking the water system of Taihu Lake basin as the research object, this paper draws the map of the water resources emergy system of the basin, and compiles the emergy analysis table. The emergy conversion rate of water resources in the basin from 2007 to 2011 is calculated. The results show that the emergy conversion rate of water resources in the river basin is increasing year by year, and the water environment of the basin is improved in recent years. In addition, the emergy conversion rate of water resources under artificial interference has increased by an average of 24.3 percent compared with that of natural water resources, and this increase is also showing an upward trend year by year. From 4.31% in 2007 to 36.4% in 2011, it shows that although the amount of water resources in the basin is abundant, the cost of safe water supply is increasing. Water shortage of water quality type will be a new challenge in the 20th century.
