对雨洪资源利用的再认识

Reunderstanding on rain and flood resources utilization

雨水和洪水是宝贵的自然资源,雨洪资源利用是具有悠久历史的重要水资源开发利用方式。近年来雨洪资源利用的实用性技术获得了蓬勃发展,但对其基本概念尚存在明显的认识误区,相关概念和术语的不规范使用给研究和实践带来了混乱。鉴于此,从有关历史和现实情况出发,根据水文学基本理论,对雨洪资源利用进行了再认识,明确了雨水、洪水的自然资源和水资源属性,阐明了雨水资源利用和洪水资源利用的基本内涵和定义,辨析了雨水资源利用和洪水资源利用之间的关系,并澄清了“雨水资源化”“洪水资源化”等术语的规范性。对雨洪资源的思考和认识有助于夯实雨洪资源安全高效利用的理论基础,为科学开展雨洪资源利用评价、规划和技术创新及应用创造了条件。

Rain and flood are valuable natural resources.Utilization of both rain and flood resources has a long history and is one of vital water resources utilization ways.In recent years,practical technologies of rain and flood resources utilization have advanced greatly,but there are still remarkable misunderstandings on their basic conceptions.Extensive use of some nonstandard terms has brought confusion to scientific research and practice.Therefore,in light of the relevant history and reality,and according to the basic theory of hydrology,a discussion on rain and flood resources utilization was carried out and preunderstanding was obtained in this research.The natural resources and water resources properties of rain and flood were clarified.Then,the basic connotation and definition of rain and flood resources utilization were summarized.And finally the relationship between rain resources utilization and flood resources utilization was analyzed.In addition,the normalization of some technical terms including so called rainwater reuse and flood reuse was clarified.This paper is helpful to eliminate the misunderstandings about rain and flood resources utilization and consolidate the theoretical basis of the safe and efficient utilization of rain and flood resources.Our understanding creates good prerequirements for the scientific evaluation,planning and technology innovation of rain and flood resources utilization.
