对雨水资源利用潜力作了最新定义,以连云港市为例,介绍了流域下游缺水区水资源分布特点及雨水资源利用现状,分别使用经验公式法与水量平衡法计算雨水资源利用潜力,绘制了不同频率雨水利用潜力趋势图。结果表明,考虑了下渗和土壤蓄水量等水文物理过程的水量平衡法计算结果更为实际、真实,可根据每月雨水利用潜力值提前配备相应潜力的雨水收集设施,以便最大化利用雨水资源。
The latest definition of rainwater resource utilization potential was made. Taking Lianyungang as an example, the water resources distribution characteristics and utilization status of rainwater resources in the lower reaches of the basin were introduced. The empirical formula method and water balance method were used respectively to calculate the potential of rainwater resources utilization. Potential trends of rainwater utilization at different frequencies. The results show that the calculation of water balance considering hydro-physical processes such as infiltration and soil water storage is more realistic and true. Rainwater harvesting facilities with corresponding potential can be provided in advance according to monthly rainfall potential value Resources.
