摘要/Abstract

摘要： 结合自然地域条件探索科学有效的屋顶绿化评价方法.以兰州城市屋顶绿化为研究对象,从设计合理性、成本投入、绿色效益和维护质量四个方面构建评价指标体系.运用模糊综合评判法对兰州屋顶绿化现状进行评价.结果表明:兰州市屋顶绿化的综合评价多处于“中”和“差”等级,存在基质理化特性不高、基础构造不完整、配套设施不健全、养护管理不到位等问题,依据评价结果提出了具体的改善途径.本文基于地区特征构建和设置的屋顶绿化评价体系指标及其权重,具有一定的科学性和有效性,可以为干旱半干旱地区城市生态环境资源管理和规划提供参考依据.

Abstract: The purpose of this paper is to explore a scientific and effective evaluation method of roof greening in combination with natural geographical conditions. The roof greening of Lanzhou city was selected as the research object. In this study, the evaluation index system is constructed from the aspects of design rationality, cost input, green benefit, and maintenance quality. The fuzzy comprehensive evaluation method is used to evaluate the roof greening status in Lanzhou. The results demonstrate that Lanzhou City's comprehensive evaluation of roof greening is mostly in the middle and poor level, which has a large space to be improved. The physical and chemical characteristic index of roof greening substrate is lower and the lack of attention to the construction of drainage and aquifer layer is the binding factor affecting the green benefits of roof greening. The insufficient investment in managed funds and general maintenance personnel with low professional ability are the restrictive factors affecting the green benefits of roof greening. In this paper, the evaluation index system and its weight about roof greening based on geographical characteristic are scientific and effective to some extent. These results can provide a reference for urban eco-environmental resource management and planning in arid and semi-arid areas.
