Simulation of Water Resources in Buerhatong River Basin

1∶250 000 contour was used to generate 0. 0012°（ 4. 32 s） of grid DEM of the basin,to simulate flow line of slope surface and gradient line,automatically draw valley line,and count catchment area at slope surface point. We organized data at the sections with 100 m of interval to simulate water system,establish coding system of river network,and build associated point with slope surface system. ＂ Hillside hydrology＂ theory simulated subsurface flow between surface water and groundwater,and used catchment water at slope surface point,gradient,valley line and depletion curve to study soil moisture distribution in the basin.

Studies on the Evolutionary Laws and Maintaining Mechanism of Renewability of the Yellow River's Water Resources

The Yellow River has a vast catchment area and historically it is the mother river of the Chinese nation. Now it serves as one of the main theatres for the on-going national campaign to develop China's western hinterland.……

流域水资源使用权定量分配方法初探

针对不同流域的复杂情况,提出了流域水资源使用权初始分配的一般原则,包括社会公平、尊重现状、基本生态需水优先、重要性和效率优先、适量预留、权利和义务相结合、民主协商、适时调整等;研究了水权分配在经济社会发展水平、水资源权属关系、水资源调控能力、生态环境、政府预留水量等方面的约束条件及其阈值的确定方法;设计了比较具有可操作性的水权分配的技术思路,包括水权分配的空间尺度和时间尺度、河流与计算单元的关系、水权分配的层次与内容、需水的合理性复核、各水平年间水权的协调等。应用该方法完成了松辽流域各典型河流水资源使用权初始分配方案的定量研究。

龙岗河流域非传统水资源综合利用潜力分析

为解决龙岗河流域经济发展需求和水资源缺乏的矛盾,减少对传统水资源的依赖,龙岗河流域应尝试以非传统水资源作为补充替代水源,并建立完善的非传统水资源利用体系及政策。此举对于形成城市节水氛围,对构建节水型城市、资源节约型城市都有其重要意义。本文以龙岗河流域实际情况为背景,阐述了该流域非传统水资源使用现状和制约因素,并对利用方向和如何推进提出了建议。
