雨洪利用作为一项系统工程,其实质是对水资源进行合理的空间和时间上的存储或调度,由于涉及到气象、水文、地质等多种影响因素,规划设计通常较为复杂。在缺乏有力的技术手段的情况下,实施效果无法科学评估,所以我国各大城市的雨洪利用仍处于起步阶段,未得到有效的推广实施。 Utilization of rainwater and flood as a systematic project is essentially a reasonable storage and dispatching of water resources in a reasonable space and time. Planning and design are usually complicated due to various factors such as meteorology, hydrology and geology. In the absence of effective technical means, the implementation effect can not be scientifically assessed. Therefore, the utilization of rain and flood in major cities in China is still in its infancy and has not been effectively promoted and implemented.
