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。
Facing the urgent situation of water resources shortage,it is particularly important to tap potential rain?flood resources.Taking Li?aocheng 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.
