摘要
在流域开展综合治理工程规划建设前,为保护水生态和水环境,需要研究综合治理工程对河道水文情势的影响.本研究利用二维水动力学模型MIKE21,以福建金溪建宁河段为研究案例,模拟研究综合治理工程对该河段水文情势的影响,结果发现河段水位增长幅度在0.1～0.3m之间,流速降低幅度在0.4～0.8m/s之间.该研究可为小流域综合治理工程水生态、水环境影响分析评估提供技术思路与方法,支撑流域和区域经济社会高质量发展.
Abstract
Before planning and constructing comprehensive management projects in a watershed,it is necessary to study the impact of such projects on river hydrology to protect the aquatic ecosystem and water environment.This study uses the two-dimensional hydrodynamic model MIKE21,taking the Jianning section of the Jinxi River in Fujian as a case study,to simulate the impact of comprehensive management projects on the hydrology of this river section.The results show that the water level in the river section increases by 0.1 to 0.3 meters,while the flow velocity decreases by 0.4 to 0.8 meters per second.This study provides technical approaches and methods for analyzing and evaluating the impacts of comprehensive management projects on the aquatic ecosystem and water environment of small watersheds,supporting high-quality economic and social development in the basin and region.
