| 摘 要： | 通过蒙特卡罗试验, 探讨了三峡工程建成后枯水期运行风险的评估方法。以GCM模拟试验结果为未来气候情景, 随机模拟了三峡地区在该气候情景下枯水期月降水量分布; 建立了三峡地区月径流-降水模型和三峡水库调度模型; 初步分析了长江三峡工程建成后在当前气候背景和可能未来气候情景下的运行风险。结果表明, 三峡水库的运行对气候变化反应敏感, 春季和冬季的发电风险有明显改变。

| Abstract: | Monte Carlo experiment is adapted to analyze the risks of the Three Gorges Reservoir operation in dry seasons. Monthly precipitation derived from general circulation models in the Three Gorges area is generated stochastically to produce the distribution under the future climate scenarios. In addition, a statistical runoff rainfall model as well as a reservoir management model is set up. The risks of the Three Gorges Project operation under the present and the future climate scenarios are thus assessed. The result indicates that the operation of the Three Gorges Project is very sensitive to climate change, and the risks of electrical power supplying by the Three Gorges Reservoir in spring and winter will change obviously. |
