【摘要】：如何定量水资源的资源价值，一直是当前研究的热点，能值理论与方法的引入，，解决了生态环境系统与人类社会系统无法统一度量的壁障，从水资源形成过程的角度度量它的价值，这方面的研究已见报道。然而，对于当前水质污染问题的突出，能值理论的研究却有所欠缺。文中针对太湖水资源主要污染源：面源污染，进行了能值计算与分析，主要研究内容和成果如下：（1）从水资源的形成过程出发，考虑人类活动与水资源自然循环之间的相互作用，对复合系统进行了能量分析。在能量分析的基础上，介绍了能值理论与方法及对水资源复合系统进行能值分析的方法。（2）绘制太湖流域水资源能值系统图，收集太湖流域水资源相关资料及数据，应用能值理论与方法，计算了2007-2011年流域水资源的资源价值，对流域水资源的价值构成及变化趋势等进行了分析评价，文中计算流域水资源平均能值—货币价值为0.82元/m3，在对计算存在缺陷作出修改调整后，达到1.09元/m3。（3）针对水质面源污染问题，对具体的农业污染源污染过程进行了过程分析。总结文献资料，提出流域各污染源污染负荷的定量计算方法；将能值理论引入，提出了污染源的能值计算方法及评价指标；（4）选取流域东岸典型城市苏州市为研究区，收集研究区2007-2011年资料与数据，对研究区主要污染源的氮磷污染负荷进行了定量计算和分析，对具体污染现状及原因进行了分析；（5）在流域水资源能值转换率及主要污染源污染负荷的计算基础上，根据污染过程分析，计算出了主要污染源污染因子氮磷的能值转换率，并结合污染源生产活动及污染现状，进行了能值分析与指标评价。计算结果为污染源污水处理过程的能值分析提供新的参数和依据；（6）对本文研究成果进行总结，提出研究中存在的问题及进一步研究的方向。
[Abstract]:How to quantify the resource value of water resources has always been the focus of current research. The introduction of emergy theory and method has solved the barrier that ecological environment system and human society system can not be unified measured. The value of water resources is measured from the point of view of the process of water resources formation, which has been reported. However, the current problem of water pollution is prominent. In this paper, the main pollution sources of water resources in Taihu Lake, namely non-point source pollution, are calculated and analyzed. The main research contents and results are as follows:. 1) considering the interaction between human activities and the natural circulation of water resources, the energy analysis of the composite system is carried out based on the energy analysis. This paper introduces the emergy theory and method and the method of emergy analysis for water resources composite system. (2) drawing a map of water resources emergy system in Taihu Lake basin, collecting relevant data and data of water resources in Taihu Lake basin, and applying emergy theory and method to calculate the resource value of water resources in the basin from 2007 to 2011. The value composition and change trend of water resources are analyzed and evaluated. The average emergency-monetary value of water resources is 0.82 yuan / m ~ (3). After modifying and adjusting the calculation defects, it reaches 1.09 yuan / m ~ (3). 3) aiming at the problem of water quality non-point source pollution, this paper analyzes the process of the pollution process of agricultural pollution source, summarizes the literature, puts forward the quantitative calculation method of pollution load of each pollution source in the basin, and introduces the emergy theory into it. The energy value calculation method and evaluation index of pollution source are put forward. 4) selecting Suzhou City, a typical city on the east bank of the basin, as the research area, collecting the data and data from 2007 to 2011, quantitative calculating and analyzing the nitrogen and phosphorus pollution load of the main pollution sources in the study area, and analyzing the specific pollution status and reasons. On the basis of the calculation of the energy conversion rate of water resources and the pollution load of main pollution sources in the basin, the emergy conversion rate of nitrogen and phosphorus of the main pollution sources is calculated according to the analysis of the pollution process, and combined with the production activities of the pollution sources and the present pollution situation, The emergy analysis and index evaluation are carried out. The calculated results provide new parameters and basis for the emergy analysis of the wastewater treatment process of the pollution source. 6) summarize the research results, put forward the existing problems in the research and the direction of further research.
