【摘要】 随着我国推进城乡统筹发展,城市各区域发展速度加快,城市规模不断扩大,生活垃圾处理场将越来越远离城市中心区域,城市生活垃圾收运系统的服务范围将更为广阔。面对这种情况,为城市的不同区域有针对性的选择生活垃圾收运模式,对构建大城市生活垃圾收运系统显得尤为重要。本文通过研究生活垃圾收运模式的影响因素,构建了特征指标体系,并运用聚类分析中的层次聚类法,对城市的不同区域进行了聚类。根据聚类分析的结果,对各区域选择合理的生活垃圾收运模式进行了分析研究。最后,引入SPSS统计分析软件,对重庆市主城各区域生活垃圾收运模式进行了聚类分析研究。具体得到了以下结论:①根据中转的次数,将生活垃圾收运模式分为直接收运模式、一级转运收运模式和多级转运收运模式。结合生活垃圾收运系统中,垃圾收集、运输和中转的方式及设备的不同,提出了适合于我国的较为典型的生活垃圾收运模式:压缩车直运模式、小压站直运模式、小型压缩收集站收运模式、压缩中转站收运模式、流动车收集收运模式和集装箱垃圾收集站收运模式等。研究了上述各种模式的特点,分析了其在国内一些典型城市的不同区域的运用情况。②通过研究生活垃圾收运模式的影响因素,构建了以人口密度、区域建成区总面积、运输距离、人均GDP、垃圾收集密度和垃圾人均产量为主的特征指标体系。运用聚类分析中的层次聚类法,对城市的不同区域进行了聚类,结果表明,城市可以分为4类区域:城市中心区域、城市次中心区域、近郊区域和远郊区域。并就如何根据聚类分析的结果,对各区域进行生活垃圾收运模式的选择进行了分析研究。③利用城市生活垃圾收运模式聚类分析方法,对重庆市主城各区域生活垃圾收运模式的选择进行了实例分析。基于重庆市主城区生活垃圾收运系统的现状,运用SPSS统计分析软件,对重庆市主城9区进行了分类,将主城区划分为了4类区域,并根据不同区域的特点,选择了合适的生活垃圾收运模式。更多还原

【Abstract】 With the balance development of urban and rural in our country, the each region of the city expand it’s scale rapidly. As a result, the Municipal Solid Waste Disposal Plant will be far away from central of the city, and the service area about collection and transportation system can be wider than before. In that case, choosing right collection and transportation mode for different region is particularly important for establishment collection and transportation system of big city. The index system of the characteristics has been constructed based on those influence factors about collection and transportation mode for Municipal Solid Waste. And each district of the city can be clustered with the Hierarchical Cluster Method. According the result, collection and transportation mode of each district can be confirmed. What’s more, Cluster analysis of the main districts of Chongqing city has been made by SPSS 13.0 software. The conclusions can be acquired:①According to the frequency of the transportation, the collection and transportation mode can be described as direct or one level mode and so on. Then the typical collection and transportation mode be proposed, which can be applied in different region of representative city.②After study the influence factor, the index system of the characteristics can be structured with density of population, build area, transportation distance, GDP per capita, collection density and per capita output for MSW. What’s more, each district of the city can be clustered with the Hierarchical Cluster Method by using that index system. The result shows that the city can be divided into four kinds area: the city center area, subcenter area, suburban area, and outer suburban area. And each area can choose the collection and transportation mode which fit for it’s characteristics.③The collection and transportation mode of each district in Chongqing can be confirmed by using cluster analysis method. Under the SPSS 13.0 software, the main district of Chongqing can have four kinds of area, and each area will choose its own collection and transportation mode.更多还原
