摘　　要：为利用概率解析法所构建的水文模型定量解析雨水收集利用系统的径流调控性能和供水保障能力,以西安市历史长序列降雨资料为依据,采用连续模拟模型和所构建的概率解析模型,解析雨水收集利用系统的水文过程和用水过程,揭示出水文性能指标与系统容积的非线性关系,验证了概率解析模型在西安市雨水收集利用系统的适用性,进而利用概率解析模型确定出西安理工大学金花校区校园雨水收集利用系统最佳容积。结果显示基于概率解析法所构建的水文模型可作为一种计算高效、使用便捷的雨水收集利用系统水文评估与设计工具,对我国海绵城市雨水收集利用系统规划、设计与评估提供了参考。This study aims to use the developed hydrologic model based on the analytical probabilistic approach for quantifying the runoff control performance and the water supply reliability of rainwater harvesting systems.Based on the long-term historical rainfall data in Xi'an City,the continuous simulation model and the proposed analytical probabilistic model were used to analyze the hydrologic and water use processes of rainwater harvesting systems.The nonlinear relationship between the hydrologic performance indicators and the storage capacity of the rainfall harvesting systems was revealed.The applicability of the analytical probabilistic model for the rainwater harvesting systems in Xi'an was verified.The analytical probabilistic model was further applied to determine the optimal size of rainwater harvesting systems in Jinhua Campus of Xi'an University of Technology.The results show that the hydrologic model based on the analytical probabilistic approach can be used as a computationally-efficient and easy-to-use hydrologic assessment and design tool of rainwater harvesting systems,which provides guidance to the planning,design and assessment for the rainwater harvesting systems in Sponge City construction in China.
