【摘要】 面对水资源短缺的紧迫形势,挖潜利用好雨洪资源尤为重要。以聊城市为例,对雨洪丰枯遭遇情况、雨洪资源量、雨洪资源利用潜力进行了分析评估,提出了雨洪资源利用总体思路和主要任务。结果表明:边界河流与市内降水年和汛期丰枯遭遇"尚可"和"有利"组合在50%左右,总体而言,一半左右年份有较好的相机调引边界河流雨洪资源的条件;聊城市多年平均雨洪资源量为9.8亿m~3,多年平均雨洪资源利用潜力为5.4亿m~3;按市内、边界河流划分,不同年型聊城市边界河流和市内河流雨洪资源利用潜力占比为85%～91%,边界河流雨洪开发潜力大,应作为雨洪开发利用的重点方向;雨洪资源利用应注重"蓄、调、渗"综合措施的应用,发挥各类工程在时间上滞蓄、平面空间上调配、竖向空间上滞渗雨洪的作用。更多还原

【Abstract】 Facing the urgent situation of water resources shortage, it is particularly important to tap potential rain-flood resources. Taking Liaocheng City as an example, the encounter of rain-flood, the amount of rain-flood resources, the potential of rain-flood resources utilization, the general idea and main tasks of rain-flood resources utilization were systematically analyzed. The results show that the "favorable" and "moderate" encounters years of boundary river and urban rainfall year of Liaocheng account for about 50%. Overall, about half of the years have relatively good conditions for diverting rain-flood resources from boundary rivers. The average annual rain-flood resources in Liaocheng is 980 million m~3 and the average utilization potential of rain-flood resources is 540 million m~3. The ratio of rain-flood resources utilization potential of boundary rivers is between 85% and 91% in different years, and the potential for rain-flood development in boundary rivers is large. When planning the utilization of rainwater resources, the diversion and utilization of rain-flood resources of boundary rivers should be fully considered.更多还原
