中文摘要：

在在改变环境条件下面的河盆以内的水周期和水资源经历深刻变化，它在河的水环境上有重要效果。由于为经济、社会的开发要求的水资源，水数量和质量正在成为水资源开发和利用的核心限制。在这篇论文，水资源的双属性，进关于评价和缺点与这些技术联系了的水数量和优秀关节的研究的进步关于水被总结并且描述数量和质量。结果显示在当前的环境条件下面，方法使用了因为对单个水身体的传统的水质量评价不能为水资源管理满足要求。而且，为河的数字模型联网的 a coupled 水动力学和水质量和适用于河水环境系统的湖为河网络流动和污染物质移植和转变过程被开发并且验证。这确认表明在模型计算的模仿的价值和监视价值之间的错误是小的，满足应用程序要求并且认识到水数量的综合、动态的模拟和河水的质量环境系统。在这个基础上，综合模拟模型被用于 Luanhe 河盆。

英文摘要：

The water cycle and water resources within river basins under changing environmental conditions undergo profound changes, which have significant effects on the water environment of the river. Owing to the water resources demanded for economic and social development, water quantity and quality are becoming the core constraints of water resources development and utilization. In this paper, the dual attributes of water resources, progress into research regarding water quantity and quality joint assessment and simulation and the shortcomings associated with these techniques are summarized and described with respect to water quantity and quality. The results indicated that under the current environmental conditions, the method used for traditional water quality assessment of single water bodies cannot meet the requirements for water resources management. Moreover, a coupled hydrodynamic and water quality numerical model for river networks and lakes that applies to the river water environment system was developed for the river network flow and pollutant migration and transformation process and validated. This validation revealed that the error between the simulated values calculated by the model and the monitored values was small, meeting the application requirements and realizing the integrated and dynamic simulation of water quantity and quality of the river water environmental system. On this basis, the integrated simulation model was applied to the Luanhe River Basin.
