【Abstract】 Nowadays there are increasingly complex ingredients of urban resident solid wastes and consequently accumulating production, resulting in the issue of residents wastes being given much attention.The management of residential solid wastes mainly consists of receiving and transporting management. This paper systematically studies various factors influencing collection and transportation management and compares collecting and transporting methods, constructing collecting and transporting model based on mathematics, as well as studies of optimized site selection of small urban resident solid wastes collecting and transporting station based on GIS. In the collection and transportation planning and managing of municipal residents solid waste in central district of Changsha city, it realizes the lower cost of urban solid waste collection and transportation and the most appropriate service radius model, designs computer implementation procedures, and actualizes quantitative analysis of city land use and the location of small waste transmit station in the condition of anistrope distribution of population. The urban solid waste collection and transportation management technical support. It also offers technical support to the urban solid waste collection and transportation management, widening the application area GIS in urban public infrastructure services from the aspect of special anlysis.The main studies are as follows:(1)Introduces the context and reasons to chose this theme, and illustrates the problems faced by the site selection of urban solid waste collection and transportation stations. Based on quantities of Access to the actual research and documentation, it analyses the factors influencing the quantity and elements of urban solid wastes, and proposes study framework focused on Changsha City central district urban solid wastes collection and transportation management. (2)Via studies of the whole process in urban solid wastes collection and transportation and analysis of domestic and international status, brings out ten kinds of urban collection and transportation schemes for mixed and classified collecting of urban solid wastes collection and transportation. as to mixed collecting and transporting,constructs models of the cost of collecting and transporting, realizing the most appropriate service radius and contrasting the cost of all kinds of collecting and transporting schemes in the most appropriate service radius. For the first time, this paper advocates the term of environmental sanitation zoning and applies it to the optimization of the mixed collecting and transporting schemes and the planning and location of small-scale transmit station.(3)On the basis of investigation on selected domestic urban solid wastes classified collecting and transporting stations and analyzing on materials,it studies the prerequisites and classification principles for implementation of classified collecting, and analyses the costs and profits of classified collecting and transporting. It provides rationalized proposals and theoretical basis to speed up domestic urban solid waste separation and collection.(4)Introduces the term of GIS and the function of spatial analysis, and illustrates the site selection of small-scale urban solid wastes collection and transportation station in Changsha City environmental sanitation plan. Makes analysis and evaluation of ideas and methods of traditional small-scale urban solid waste collection and transportation station location. Describes how geographic information systems spatial analysis is applied in site planning, and what advantages it brings to urban infrastructure planning with the development of computers and GIS.(5)Summarizes the principles and methods in site selection of downtown urban solid wastes collection and transportation station,considers factors influencing the site selection of it,such as land-use characters,population distribution,population density,quantity of solid wastes collected and transported and transportation. Proposed a reasonable standard for population density based on environment sanitation zoning in the case of urban land use, anistrope population distribution, and makes the lowest cost service radius as an indicator to decide whether the location of small-scale waste transfer station is reasonable. constitutes the spatial images and related characteristic statistics of Changsha City’s central district small-scale solid waste collecting station location,constructs computer realizing program and planning system based on GIS support for optimizing the urban solid wastes collection and transportation station location, and then decides optimized location area and service scale. In terms of covering proportion and costs of small-scale solid waste collecting station, makes contrast of the recent situation of Changsha central district small solid waste collecting station, environmental sanitation planning and optimizing location schemes, thus offers summary evaluation, and gives advices on implementation measures, so as to assist managing decision in urban solid wastes collection and transportation station planning technically.(6)From the point of management, it studies and discusses the characteristics of urban solid wastes collection and transportation management. As an environmental management, environmental effectiveness is the primary objective of collection and transportation management.Via discussing the concepts and elements in management decision-making systems, analyzes the decision-making content and objectives in collection and transportation management system, proposes an overall design for urban solid waste collection and transportation. Emphasizes the application of GIS into information collecting, data analyzing and the resulting outputting has a strong advantage, in order to change the static planning into a dynamic programming. At the same time, the role of collection and transportation system management mechanisms such as induction mechanisms, incentives mechanisms, and enforcement mechanisms have been studied. Compares four patterns in collection and transportation management system in and abroad at present, and points out the enterprise and industrialization is the trend the collection and transportation management system would develop into.The paper also goes deep into discussing the collection and transportation management and operation systems, analyzing the responsibilities in urban solid wastes collection and transportation management and operation systems systematically,and proposes advices on measures to ensure the fulfilling of the managing goals and the service qualities, therefore, it will be valuable on some degrees as a reference for city urban solid wastes managing department and decision-makers.更多还原
