摘　　要：论述了疏勒河流域水资源形成与径流特征,对水资源分布格局变化及水资源利用效率提高对水循环系统的影响进行了分析.总结中游盆地生态景观、植被优势种的分布与地下水之间的关系,提出了盆地植被优势种的演化模式.针对存在的问题,构建盆地水资源开发利用的经济、社会、生态环境协调发展的多目标管理模型.将盆地划分为7个管理亚区、3个方案、4个时段,并用拉格朗日乘子法与目标规划相结合的多目标交互式算法对模型进行求解运算,得出经济效益最大、社会效益最优、生态效益最佳几个宏观指标.对比分析了最终满意解的水量分配,针对未来水资源利用中存在的问题,提出了相应的对策措施.In this paper, the formation characteristics and runoff condition of water resources, and the influence of change of the location and enhance the utilization ratio of water resources on local water cycle system are discussed firstly. Secondly, the relation between the distribution and the vegetation dominate species and groundwater level in the middle reaches of the river is summarized, also a model of the vegetation dominant species change in this basin is suggested. Furthermore, the change of groundwater recharge and allowance output after construction of Changma Irrigation Developing Project is predicated.By using a groundwater flow model, the forthcoming groundwater level and the change of eco- environment is predicated after Changma Irrigation Developing Project. Aiming at problem in water resources utilization, a multi-objective management model for coordinating the relationship among economy, society and eco-environment is build. Ten management sub-regions are divided according to water resources utilization. The model is solved by a new interactive method, based on Lagrange multiple and multi-objective programming. A series of results at the target of the largest economic interest, best social welfare and excellent exobiological benefit are gained, and the best compromise solutions are analyzed. At last, in connection with the problems in water resources utilization, some countermeasures and ways are put forward.
