城市绿化的快速发展,产生了一些值得关注的问题和矛盾,植物生理产物——园林绿化废弃物的处置就是其中之一。由于长期将园林绿化废弃物视为垃圾,不仅增加了城市环境管理的压力,更使绿地生态系统物质循环和能量流动缺失,影响绿地自我调控和发展能力,降低城市绿地改善城市环境的功能和作用。 The rapid development of urban greening has produced some problems and contradictions of concern. The disposal of landscaping wastes, one of plant physiology products, is one of them. Since long-term landscaping wastes are regarded as rubbish, it not only increases the pressure on urban environmental management, but also shortens the material circulation and energy flow of the green space ecosystem, affects the self-regulation and development capacity of green space and reduces the functions and roles of urban green space in improving the urban environment .
