| 中文摘要: |
| 本文以黄河下游沿黄地区供用水系统为例，针对该地区用水系统与黄河来水的不同步性，建立了水资源系统风险分析模拟模型。描述了蒙特卡洛(M-C)随机模拟技术求解风险模拟模型的原理。对黄河下游供用水系统在不同用水规模情况下的缺水风险进行了随机模拟。结果表明：黄河下游沿黄地区在没有外流域水输入前及用水定额没有较大变化的情况下，其灌溉规模以不超过233万hm2为宜。 |
| 英文摘要: |
| The risk analysis simulation model for water resources in the downstream area of Yellow River is established in this paper. The non-synchronous characteristic of the relationship between water consumption and runoff of the Yellow River is considered. the Monte Carlo method is applied to the modeling. The risks of water shortage under the conditions of various scale of water consumption are simulated randomly. The result indicates that the irrigation area should be limited to less than 2,330,000hm2, in case new water resources failed to be developed and the norm of water consumption not being significantly change. |
