Abstract:

澜沧江–湄公河是流经五国的东南亚第一长河，随着澜沧江干流出境前最后一个水电站景洪站的投入运行，其对澜沧江出境水量变化的影响倍受下游国家及国际社会的关注。本文运用景洪电站下游的允景洪、关累水文站径流资料，开展景洪站建立前后对其下游河段径流量的影响研究。结果显示，1) 建库后的下泄水量较建库前上游来水量具有明显减少趋势；2) 枯季时，建库后下泄水量较建库前上游来水量增大，而汛期则体现为减少；3) 枯季的下泄水量比重占全年下泄水量的比重增大，且损失水量随枯季下泄水量的增大而增大。该研究结果可为澜沧江流域水电开发及其流域管理提供基础依据。
The Lancang-Mekong River is the longest river in Southeast Asia flowing through five countries. With the operation of Jinghong Hydropower Station, the last hydroelectric station before the departure of the main stream of the Lancang River, its impact on the changes of the transboundary discharge of the Lancang River has attracted much attention from the downstream countries and the international community. Based on the runoff data of Yunjinghong and Guanlei hydrological stations in the lower reaches of Jinghong Hydropower Station, this paper studies the influence of Jinghong Hydropower Station on the runoff of the lower reaches before and after the construction of Jinghong Hydropower Station. The results show that: 1) the amount of water discharged from the upper reaches of the reservoir after the construction of the reservoir has a significant decreasing trend; 2) in dry season, the amount of water discharged after the construction of the reservoir increases compared with the amount of water coming from the upper reaches before the construction of the reservoir, while in flood season it decreases; 3) the proportion of water discharged from the lower season to the annual amount of water discharged increases, and the amount of water lost increases with the increase of the amount of water discharged in dry season. The research results can provide a basic reference for hydropower development and watershed management in Lancang River Basin.
