A study on solid waste management in wide area

1.开展了固体废物铁路运输现状调查，对铁路固体废物运输现状进行了调查，探讨了固体废物铁路运输的技术和体制问题。从经济学角度研究固体废物的广域运输传统上，“污染者付费原则”是固体废物管理的基础，它促使地方政府在市辖区内处理固体废物。本研究从经济学角度对广域管理的相关问题进行了分析。并对长途运输方式的选择和处理设施选址方法进行了分析。大型垃圾填埋场环境影响研究大型垃圾填埋场采用常规路面进行填埋，会引起小气候变化，引起温度升高。然而，保水砖和人行道被证明能够将热状况保持在与天然土壤相同的水平。研究了地表改善对城市热状况的影响。此外，还对保水砌块在屋面材料中的应用进行了研究。广域固体废物运输“应然图景”研究从健康和环境的角度研究固体废物铁路运输的作用。对广域铁路运输的“应景”也进行了调查。

1. Survey on Railway Transportation of Solid WasteField surveys were carried out to investigate current situation of solid waste transportation by railway and technical and institutional problems were discussed.2. Study on wide-area transportation of solid waste from economic point of viewTraditionally, "polluter pay principle" was the basis of solid waste management, which promoted local authorities to magage solid wastes inside municipality boudaries. In this study, problems related with wide-area management were analyzed form economic point of view. Also, selection of long-distance transportation methods and site selection method of treatment facilities were also analized.3. Study on environmental impact of large landfill sitesLarge-scale solid waste landfill with conventional pavement will lead to the change on micro-climate and causes temperature raise. However, water retainable blocks and pavements were proved to be able to maintain thermal condition at the same level as the natural soil. The effect of land surface improvement on the urban thermal condition was also investigated. In addition, application of water retainable blocks to roofing material was also investigated.4. Study on "Should-be picture" of solid waste transportation in wide areaThe role of railway transportation of solid waste was studies from the standpoint of health and environment. "Should-be picture" of wide-area railway transportation was also investigated.
