城市垃圾危机、土地资源枯竭、城市交通拥堵、生态环境恶化等“城市病”严重阻碍了现代城市的可持续发展。本文通过对城市“垃圾危机”现象的说明，揭示了生活垃圾产生量逐年增加，垃圾处置能力不足以及收运方式不合理，从而导致了“垃圾围城”。解决垃圾危机的有效方法，除了做好垃圾分类以及垃圾“减量化、资源化、无害化”工作外，提高垃圾处置能力和改善收运方式非常重要。进一步，本文通过对上海市建设城市地下环境物流系统的规划与概念设计说明，指出了地下环境物流系统能够为缓解垃圾危机提供一条重要出路。此外，发展地下环境物流系统能够减少交通拥堵、改善城市环境，带动相关高新技术研究，促进城市的可持续发展。
City waste crisis, land resource exhaustion, urban traffic congestion, and ecological environment deterioration have seriously hindered the modern urban sustainable development. By describing "waste crisis", it is revealed that the increasing quantity of waste output, the insufficient waste disposal capacity, and the unreasonable waste collection and transportation methods are the cause for the problem of "waste siege" in many big cities. In addition to waste classification and "reduce, reuse, recycle" policy, an effective method for solving waste crisis is to improve the waste disposal capacity as well as the collection and transportation method. Furthermore, the concept of underground environment freight transportation is explained, and plan and conceptual design of urban underground domestic waste transfer logistics system in Shanghai are introduced. It is pointed out that the underground environment freight transportation system provides an important and feasible way to relieve the waste crisis. Besides, underground environment freight transportation system can reduce traffic congestion, improve urban environment, lead to related high-tech researches, and promote the sustainable development of modern cities.
