摘要
城市高密度发展与绿色空间需求的矛盾促使城市公共空间向立体化方向延展,为绿色屋顶的发展带来了机遇,绿色屋顶的生态系统服务功能可为人们提供生态、经济和社会效益。参考生态系统服务的通用国际分类(CICES)体系和深圳生态系统生产总值(GEP)评估指标体系,通过文献研究选取评估指标和决策方案,使用层次分析法(AHP)和专家评估法,首次构建了绿色屋顶的生态系统服务评估模型,并通过案例研究与模型结果进行对比分析,结果表明:1)在生态系统服务中,调节和维持服务在准则层中最为重要,气候调节在指标层中最为重要;2)在5种绿色屋顶类型中,生物多样性屋顶最为重要;3)专家对绿色屋顶生态系统服务的重要性评估在一定程度上可反映实际项目中决策者对绿色屋顶的主导生态系统服务功能的定位。该评估模型具有一定的应用价值,对辅助城市绿色屋顶规划布局的选址和选型具有重要意义。
The contradiction between urban high-density development and the demand for green space promotes the three-dimensional extension of urban public space,which brings opportunities for the development of green roofs.The functions of ecosystem services of green roofs can provide people with ecological,economic,and social benefits.Based on the system for Common International Classification of Ecosystem Services(CICES)and the indicator system for evaluating Gross Ecosystem Product(GEP)of Shenzhen,this research selects evaluation indicators and decision-making schemes through literature research and,for the first time,builds an ecosystem services evaluation model for green roofs with the analytic hierarchy process(AHP)and the specialist evaluation method.Additionally,a comparative analysis is conducted based on case study and model results,which shows that:1)among all ecosystem services,regulation and maintenance services are the most important in the criterion layer,and climate regulation is the most important in the indicator layer;2)among five green roof types,biodiversity roof is considered the most important;3)specialist evaluation on the importance of ecosystem services of green roofs can,to a certain extent,reflect the positioning by decision-makers of the functions of main ecosystem services of green roofs in actual projects.The evaluation model has some application value and is of great significance to the planning and layout of urban green roofs,especially in terms of site and type selection.
