河流生态修复工程中的综合治理技术探讨——以贾鲁河综合治理工程为例

Discussion on Comprehensive Management Technology in River Ecological Restoration Engineering:Taking the Comprehensive Management Project of Jialu River as an Example

贾鲁河发源于新密、荥阳两市交界处,流经郑州的西部、北部、在东部出境,环抱郑州市区。是郑州人民的母亲河,是郑州市的骨干河道,承担着城市防洪及水源调蓄的重要责任。近年来,因着贾鲁河河道萎缩、功能衰退、水生态恶化等问题的日益凸显,使其不仅无法实现城市的水源补给和防洪调蓄功能,还一度被国家列入黑臭水体重点整治清单。本文基于贾鲁河基流匮乏、河岸窄不成形、多闸坝、重污染等现状特点,对其进行具有针对性的水生态修复综合治理技术的应用探讨。

The Jialu River originates at the junction of Xinmi and Xingyang cities,flows through the west and north of Zhengzhou,and exits in the east,surrounding the urban area of Zhengzhou.It is the mother river of the people of Zhengzhou and the backbone river of Zhengzhou city,responsible for urban flood control and water source regulation and storage.In recent years,due to the increasingly prominent problems of shrinking,declining functions,and deteriorating water ecology of the Jialu River,it has not only been unable to achieve urban water supply and flood control and storage functions,but has also been included in the national key remediation list for black and odorous water bodies.This article explores the application of targeted water ecological restoration and comprehensive management technologies based on the current characteristics of the Jialu River,such as lack of basic flow,narrow and unformed river banks,multiple gates and dams,and heavy pollution.
