【摘要】：湖北省作为国家住房和城乡建设部“城乡生活垃圾统筹治理”试点省份,已启动城乡垃圾统筹治理工作。目前我国对城乡垃圾治理问题缺乏系统研究,特别是在城乡生活垃圾统筹治理的现状评估和系统设施的优化布局方面缺乏合理的方法。本文在对湖北省城乡生活垃圾统筹治理现状进行实地调研和相关资料调查、统计的基础上构建模糊综合评价模型进行现状分析与评价,找出其制约因素,并进行地区间水平差异比较及分析。同时,针对不同城乡生活垃圾统筹治理处理模式构建系统设施布局最小成本模型并进行模型简化和修正。本研究基于课题组开展的湖北省十三五城乡生活垃圾统筹治理规划研究和若干个县域的城乡垃圾统筹治理规划研究背景,采用建立的模型,通过实证研究得出以下结论:(1)通过定性、半定量及构建模糊综合评价模型定量分析的多角度、多方法分析与评价湖北省城乡生活垃圾治理现状,可以看出:湖北省目前城乡生活垃圾治理现状整体较差,各地区之间、城区与农村之间治理现状由于经济条件及政策因素差异显著,而治理设施建设及资金是制约湖北省城乡生活垃圾统筹治理的主要因素。(2)通过将最小成本模型应用于随县城乡生活垃圾统筹治理布局优化实证研究表明:城乡生活垃圾统筹治理重在布局,通过最小成本模型得到的最优方案较最劣方案总成本降低了15%以上,尤其转运站成本降低了43%,运输成本降低了60%,经济优化作用明显。同时,通过多方案比较和分析发现在布局过程中,不应盲从“村收集、镇转运、县处理”模式,而应在该模式的基础上,综合考虑道路交通、运输距离及垃圾产量等因素的影响,特别是山地、丘陵等交通状况较差、运输距离较大地区。片区划分应尽量以重点镇为中心,以3-4个乡镇为宜,对运输距离太远、地理单元比较独立的地区应优选小范围独立组团。
[Abstract]:Hubei Province, as a pilot province of the Ministry of Housing and Urban-Rural Construction, "Urban and rural domestic waste management" pilot province, has started the urban and rural garbage management work.At present, there is a lack of systematic research on urban and rural garbage treatment in China, especially in the evaluation of the status quo of urban and rural domestic waste management as a whole and the lack of reasonable methods in optimizing the layout of system facilities.In this paper, the status quo of urban and rural municipal solid waste management in Hubei Province is investigated on the spot and related data investigation. On the basis of statistics, a fuzzy comprehensive evaluation model is constructed to analyze and evaluate the status quo, and find out the restrictive factors.Regional differences were compared and analyzed.At the same time, the minimum cost model of system facility layout is constructed, simplified and modified according to the different urban and rural municipal solid waste management and disposal mode.This study is based on the research background of urban and rural municipal solid waste (MSW) management planning in Hubei Province in the 13th Five-Year Plan and the urban and rural garbage management planning in several counties, and adopts the established model.Through the empirical research, the following conclusions are drawn: (1) through qualitative, semi-quantitative and quantitative analysis of fuzzy comprehensive evaluation model, the paper analyzes and evaluates the present situation of municipal solid waste management in urban and rural areas in Hubei Province from multiple angles and methods.It can be seen that the present situation of municipal solid waste treatment in urban and rural areas is relatively poor in Hubei Province, and there are significant differences between different regions and between urban and rural areas due to economic conditions and policy factors.The construction of governance facilities and funds are the main factors restricting the overall management of urban and rural domestic waste in Hubei Province. (2) through the application of the minimum cost model to the optimization of urban and rural municipal solid waste management layout optimization empirical research shows that: urban and rural students: urban and rural studentsThe overall management of living garbage is focused on layout.The optimal scheme obtained by the minimum cost model is more than 15% lower than the total cost of the worst scheme, especially the transfer station cost is reduced by 43%, the transportation cost is reduced by 60%, and the economic optimization is obvious.At the same time, through the comparison and analysis of multiple schemes, it is found that in the process of layout, we should not blindly follow the "village collection, town transit, county processing" model, but should consider the road traffic comprehensively on the basis of this model.The influence of transportation distance and garbage yield, especially in mountainous and hilly areas, is poor, and the transportation distance is relatively large.As far as possible, the key towns should be taken as the center, 3-4 towns as the appropriate areas, the transportation distance is too long, and the areas with independent geographical units should be selected as small independent groups as possible.
