【摘要】：如何定量水資源的資源價(jià)值，一直是當(dāng)前研究的熱點(diǎn)，能值理論與方法的引入，，解決了生態(tài)環(huán)境系統(tǒng)與人類(lèi)社會(huì)系統(tǒng)無(wú)法統(tǒng)一度量的壁障，從水資源形成過(guò)程的角度度量它的價(jià)值，這方面的研究已見(jiàn)報(bào)道。然而，對(duì)于當(dāng)前水質(zhì)污染問(wèn)題的突出，能值理論的研究卻有所欠缺。文中針對(duì)太湖水資源主要污染源：面源污染，進(jìn)行了能值計(jì)算與分析，主要研究?jī)?nèi)容和成果如下： （1）從水資源的形成過(guò)程出發(fā)，考慮人類(lèi)活動(dòng)與水資源自然循環(huán)之間的相互作用，對(duì)復(fù)合系統(tǒng)進(jìn)行了能量分析。在能量分析的基礎(chǔ)上，介紹了能值理論與方法及對(duì)水資源復(fù)合系統(tǒng)進(jìn)行能值分析的方法。 （2）繪制太湖流域水資源能值系統(tǒng)圖，收集太湖流域水資源相關(guān)資料及數(shù)據(jù)，應(yīng)用能值理論與方法，計(jì)算了2007-2011年流域水資源的資源價(jià)值，對(duì)流域水資源的價(jià)值構(gòu)成及變化趨勢(shì)等進(jìn)行了分析評(píng)價(jià)，文中計(jì)算流域水資源平均能值—貨幣價(jià)值為0.82元/m3，在對(duì)計(jì)算存在缺陷作出修改調(diào)整后，達(dá)到1.09元/m3。 （3）針對(duì)水質(zhì)面源污染問(wèn)題，對(duì)具體的農(nóng)業(yè)污染源污染過(guò)程進(jìn)行了過(guò)程分析。總結(jié)文獻(xiàn)資料，提出流域各污染源污染負(fù)荷的定量計(jì)算方法；將能值理論引入，提出了污染源的能值計(jì)算方法及評(píng)價(jià)指標(biāo)； （4）選取流域東岸典型城市蘇州市為研究區(qū)，收集研究區(qū)2007-2011年資料與數(shù)據(jù)，對(duì)研究區(qū)主要污染源的氮磷污染負(fù)荷進(jìn)行了定量計(jì)算和分析，對(duì)具體污染現(xiàn)狀及原因進(jìn)行了分析； （5）在流域水資源能值轉(zhuǎn)換率及主要污染源污染負(fù)荷的計(jì)算基礎(chǔ)上，根據(jù)污染過(guò)程分析，計(jì)算出了主要污染源污染因子氮磷的能值轉(zhuǎn)換率，并結(jié)合污染源生產(chǎn)活動(dòng)及污染現(xiàn)狀，進(jìn)行了能值分析與指標(biāo)評(píng)價(jià)。計(jì)算結(jié)果為污染源污水處理過(guò)程的能值分析提供新的參數(shù)和依據(jù)； （6）對(duì)本文研究成果進(jìn)行總結(jié)，提出研究中存在的問(wèn)題及進(jìn)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.
