摘要
在调查塔里木河下游各子区生态用水需求的基础上,采用带约束条件的非线性优化理论建立了塔里木河下游各子区优化分配水量模型。采用Kuhn-Tucker条件,对模型进行求解,合理分配了各子区的输水水量。计算结果表明,通过向塔里木河下游河道输水3.4亿m3,可改善下游生态面积达1 490 km2。所建模型为将来的应急输水及水资源的合理配置提供了技术支持。
According to the investigated water demand of various sub-regions in the lower reaches of Tarim river, the paper establishes and solves the optimal allocation model for the water deliveries by using the nonlinear optimization theory with the constrained conditions. By employing the famous Kuhn-Tucker condition method, this paper solves the optimal allocation model for the water deliveries to the lower reaches of Tarim River and obtains the reasonable allocation of water quantity for various sub-regions of the lower reaches of Tarim River. The result indicates that the improved eco-area of 1490 km^2 is achived through the water deliveries （3.4 ×10^8m^3） to the lower of Tarim river. This reasonable allocation model of water quantity will provide technical support for the water deliveries in times of emergency in the future.
