多维尺度配水模型研究

针对传统一维配水模型只能考虑1个变量的缺点,用多维尺度(MDS)模型构造了适应复杂流域的包含配水水量、用水区位置和用水区需水概率等变量的多维实时配水模型,并以黄河流域天然径流的配置为例,用MDS配水模型计算了黄河干流节点在一定区域需水概率情况下,天然径流量的配置情况。与传统一维配水模型计算结果相比,MDS配水模型可以分区域计算天然径流量的配置情况,并可以计算区域需水变化情况下各区域水量配置的调配情况。该模型的建立为区域的实时配水决策提供了方法上的参考。

Study of MDS water allocation model

Compared with the traditional one-dimensional water allocation model in consideration of only one variable,the multidimensional real time water allocation based on the mutidimensional scaling (MDS) takes water quantity,location of water user and probability of water requirement into consideration. The allocation of the natural runoff was calculated by using MDS under the probabilities of water requirement in main stream of the Yellow River valley. To sum up,MDS water allocation model can not only calculate the different node's water allocation, but also indicate the node's water allocation change. The construction of the model provides a good way for real time water allocation.
