Research and Practice on the Influence of Hydropower Station Construction on River Connectivity in the Process of Urbanization by WANG Shenfang, YANG Xiaoling, LIANG Wenshan

“…River connectivity features longitudinal,lateral,and vertical dimensions,as well as time.Specifically,the longitudinal dimension (longitudinal connectivity) is highly disturbed and widely affected by human activities in the process of urbanization.Based on the research and practice of the longitudinal river connectivity both in China and abroad in terms of concepts,research mechanisms,and calculation methods,this paper took the Nanshan River Basin in Yunfu city,Guangdong Province as an example and adopted the VCI,barrier coefficient,improved barrier coefficient,and DCI methods to quantitatively evaluate the influence of hydropower station construction on longitudinal river connectivity.In addition,by calculating the impact of each hydropower station on the connectivity,the paper proposed suggestions for restoring the river connectivity in a targeted manner,which provides a reference model for the development and construction of water conservancy and hydropower and the management of small and medium-sized river basins.…”

Research on Water Resources Allocation in Xiangxi River Basin by JING Xiaoju, HUANG Zhiqiang, DANG Xiang, ZHANG Ruigang

“…In view of the low level of exploitation and utilization of water resources and the shortage of water conservancy facilities in Xiangxi River Basin,and in order to solve the water resources shortage in local areas and realize the rational allocation of water resources,this paper reasonably predicts the water demand according to the current water use level and the future economic and social development and water-saving potential,calculates the available water supply according to the conditions of existing water sources and the development and utilization plan,analyzes the supply and demand balance of water resources by taking county or region as unit,and puts forward the water resources allocation scheme in Xiangxi River Basin.After secondary analysis of supply and demand balance,84 270 000 m³ of water will be allocated in 2030 to achieve the balance between supply and demand.The results will provide theoretical reference for reasonable and balanced allocation of water resources and promote sustainable utilization of water resources.…”
