【摘要】：近年來,隨著我國經(jīng)濟的快速發(fā)展和新型城鎮(zhèn)化進程的不斷加深,人民的生活水平不斷提高,生活垃圾的產(chǎn)量也與日俱增,“垃圾圍城”的困境正日益成為當下亟待解決的環(huán)保難題。當前我國主要采取衛(wèi)生填埋方式處理生活垃圾,當垃圾填埋場填埋飽和時要關閉停止使用并進行封場管理,以此控制環(huán)境污染、抑制疾病傳播、促進生態(tài)恢復和加快土地恢復利用。對封場項目的投資方案進行評價研究,根據(jù)評價結(jié)果選取綜合效益最佳的投資方案是科學合理的進行封場的關鍵。在實際生活中,垃圾填埋場封場項目基于經(jīng)濟效益、環(huán)境效益和社會效益的綜合效益是決定該類項目投資決策的關鍵因素。為此,論文梳理了國內(nèi)外關于垃圾填埋場的研究進展和項目效益的研究進展,介紹了封場的相關概念、投資方案和投資方案評價的相關概念,分析了垃圾填埋場封場項目的投資特點和垃圾填埋場封場項目投資評價要素,在綜合考慮經(jīng)濟效益、環(huán)境效益、社會效益的基礎上,結(jié)合評價指標的選取原則和步驟,建立了3個層次3個因素12個指標的垃圾填埋場封場項目投資方案綜合效益評價指標體系;通過比較主觀賦值法和客觀賦值法各自的優(yōu)缺點后選定主觀賦值法中的層次分析法作為指標權重的確定方法,并按照層次分析法的步驟確定了指標權重;通過比較投資效益綜合評價的幾種常用方法的優(yōu)缺點后選取模糊層次綜合評價法作為垃圾填埋場封場項目投資方案綜合效益的評價方法,并依據(jù)模糊層次綜合評價法的步驟建立了評價模型,用評價模型對垃圾填埋場封場項目投資方案的效益進行了綜合評價;最后結(jié)合實際案例運用評價模型對投資方案進行評價研究得出評價結(jié)果,驗證了該方法的科學性和實用性,能為此類項目的投資決策提供參考。
[Abstract]:In recent years, with the rapid development of our economy and the deepening of the new urbanization process, the living standards of the people have been continuously improved. The production of domestic waste is also increasing, and the plight of "garbage besieging" is becoming an urgent environmental problem to be solved. Currently, sanitary landfills are mainly used to dispose of domestic waste in China. In order to control environmental pollution, restrain the spread of disease, promote ecological restoration and accelerate land restoration and utilization, the landfill landfill should be closed and closed when landfill is saturated, and the investment scheme of the project should be evaluated and studied, so as to control the environmental pollution, restrain the spread of disease, promote ecological restoration and accelerate the utilization of land. According to the evaluation results, it is the key to select the best comprehensive benefit investment scheme to seal the site scientifically and reasonably. In actual life, the landfill sealing project is based on economic benefits. The comprehensive benefit of environmental and social benefits is the key factor to decide the investment decision of this kind of project. Therefore, this paper reviews the research progress of landfill site at home and abroad and the research progress of project benefit, and introduces the related concepts of sealing site. The related concepts of investment scheme and investment scheme evaluation are analyzed. The investment characteristics and investment evaluation elements of landfill sealing project are analyzed. On the basis of comprehensive consideration of economic benefit, environmental benefit and social benefit, Combined with the selection principles and steps of the evaluation index, the comprehensive benefit evaluation index system of the landfill sealing project investment scheme was established with 3 levels, 3 factors and 12 indexes. By comparing the advantages and disadvantages of subjective assignment method and objective assignment method, the analytic hierarchy process (AHP) in subjective assignment method is selected as the determination method of index weight, and the index weight is determined according to the steps of AHP. By comparing the advantages and disadvantages of several common methods of comprehensive evaluation of investment benefit, the fuzzy level comprehensive evaluation method is selected as the comprehensive benefit evaluation method for the investment scheme of landfill sealing project. The evaluation model is established according to the steps of the fuzzy hierarchy comprehensive evaluation method, and the benefit of the investment scheme of the landfill sealing project is comprehensively evaluated by the evaluation model. Finally, the evaluation results are obtained by using the evaluation model in actual cases, which verifies the scientificity and practicability of the method, and can provide a reference for the investment decision of this kind of projects.
