澜沧江-湄公河流域跨境水量-水能-生态互馈关系模拟
Simulation of transboundary water-hydropower-ecology nexus in Lancang-Mekong Basin
摘要
Abstract
Lancang-Mekong River is an important international river in Asia,the interactions of its water-hydropower-ecology is a significant basis for the negotiations of riparian countries.This paper selects the annual power production of three hydropower stations on the Lancang River,which are located in the nearest to the boundary (i.e.,the largest impact to downstream),to represent hydropower aspect.The defined ecological alteration coefficients are selected to represent hydrological aspect,while five downstream countries' agricultural water withdrawal from the mainstream are chosen as the representation of water supply aspect.In addition,hydropower generation and environmental flow are optimized by applying a GAMS model,as well as the downstream agricultural water withdrawal is simulated by employing the WEAP model.Thus,water-hydropower-ecology nexus among the five downstream countries is conducted.It is concluded that hydropower is competing with environmental flow but coordinating with agricultural water supply.Some differences are found among the interactions of water-hydropower-ecology nexus under different water withdrawal scenarios.Agricultural water supply is influenced by hydropower generation by different degree in different scenarios,and increasing hydropower generation in China has positive effects on the irrigation of downstream countries but negative impacts on environmental flow.Thus,basin scale regulation is needed.关键词
