摘要
受厄尔尼诺现象的影响,2016年枯季澜沧江-湄公河流域各国均遭受到了不同程度的旱灾,特别是湄公河三角洲地区遭受了近百年来最严重的旱情。为此,中国政府通过加大景洪水库出库流量,来对湄公河实施"三阶段"应急补水以帮助湄公河流域国家应对旱情。根据澜沧江-湄公河流域干流主要控制水文站点的水文气象资料,对应急补水传播时间及其对湄公河水文情势产生的影响进行了分析。分析结果表明:中国的澜沧江水库实施的应急补水措施增加了湄公河干流的流量,抬升了其下游的水位,对帮助湄公河流域国家应对旱情发挥了积极有效的作用。
Due to the effects of the super El Nino during the dry season of 2016,all the countries in the Lancang-Mekong Basin suffered the drought disasters in various degrees,especially the Mekong Delta was struck by the most severe drought in the past hundred years. In this case,Chinese government decided to implement an emergency water supplement to the Mekong River in a ＇three-phase plan＇ by increasing the water discharge from Yunnan＇s Jinghong Reservoir. In this study,the analysis covers flow propagation along the mainstream,and hydrological influence of the emergency water supplement in 2016 on the Mekong mainstream based on the water level and discharge data of hydrological stations on the Lancang-Mekong mainstream and meteorology data in the basin. It is found that the emergency water supplement from China increased water level and discharge along the Mekong mainstream,helping the drought mitigation in the Mekong basin countries.
