摘　　要：目前生态植草沟构型改良设计有待优化及进行广泛应用。基于试验设计生态植草沟的最佳构型,进行不同降雨重现期植草沟调蓄性能的试验,阐明不同降雨强度对植草沟产流的影响,选择调蓄性能优良的植草沟。研究植草沟对机场飞行区道路地表径流的调控,既包括植草沟的水量调蓄试验、填料物理性质对比试验,又包括植草沟的构建及应用模型模拟植草沟、装置参数的灵敏性分析、不同植草沟装置参数条件下的调蓄效果分析,该研究可为植草沟的应用提供理论指导。At present,the design of ecological grass swale has much room for improvement and widespread application.Based on experiments,the optimal structure of ecological grass swale is designed and the performance of flood storage and detention in different rainfall recurrence periods is tested so as to clarify the influence of different rainfall intensity on the flow yield of grass swale and to select the grass swale with the optimum performance.The research of the regulation of grass swale on road surface runoff in airport flight area includes not only the experiments about regulation and storage of water quantity,contrast experiments of physical properties of fillers,but also the establishment and application model of grass swale,the sensitivity analysis of plant parameters,regulation and storage effect analysis of different planting grass swale de⁃vice parameters,which offers theoretical guidance for the application of the grass swale.
