陕西省渭河流域耗水研究

为强化水资源的严格管理和流域水资源的持续利用,根据实测资料对陕西省渭河流域的水量平衡进行了分析,研究了流域耗水类型、耗水组成及其特点。结果表明,流域各用水部门的耗水水源基本上以地下水为主,其中农村生活比例最大,为75.47%,工业和城镇生活占50%左右;人类利用水资源活动影响了水资源的径流量和水质质量。     

Effect of water and sediment regulation on lower Yellow River

According to the results of the water and sediment regulations of the Yellow River in year 2002-2007, the effect of erosion and deposition on the lower reaches, the amount and distribution of erosion and deposition in the river mouth area, the adjustment of river regime, the effect of river regulation projects and changes of flowing capacity of the channel are analyzed. It is revealed that the water and sediment regulation is efficient to reduce deposition and improve the flowing capacity and the conditions of sediment transport.     

安徽沿淮经济带城镇体系空间布局研究

安徽沿淮经济带现代城镇体系初具雏形,但城镇化绝对水平仍然较低且内部发展不平衡,城市区域带动能力偏弱,城镇基础设施建设相对落后,区域人口外流逐渐增多。在准确预测经济带2013—2030年人口规模和城镇化水平前提下,综合运用PCA方法和引力模型确定经济带区域中心城市并测度其辐射强度,提出应充分考虑沿淮经济带安徽段实际经济社会发展水平和生态资源环境条件,依托沿淮经济带现有的城镇空间布局重点和产业发展基础,坚持城镇发展与资源、环境相协调,实施核心城市引领、中心城市带动战略,最终形成安徽沿淮经济带“一轴、双组团、多节点”的开放型、网络状城镇空间结构。

Application of WEAP Simulation Model to Hengshui City Water Planning

Like many river basins in China, water resources in the Fudong Pai River are almost fully allocated. This paper seeks to assess and evaluate water resource problems using water evaluation and planning (WEAP) model via its application to Hengshui Basin of Fudong Pai River. This model allows the simulation and analysis of various water allocation scenarios and, above all, scenarios of users' behavior. Water demand management is one of the options discussed in detail. Simulations are proposed for diverse climatic situations from dry years to normal years and results are discussed. Within the limits of data availability, it appears that most water users are not able to meet all their requirements from the river, and that even the ecological reserve will not be fully met during certain years. But the adoption of water demand management procedures offers opportunities for remedying this situation during normal hydrological years. However, it appears that demand management alone will not suffice during dry years. Nevertheless, the ease of use of the model and its user-friendly interfaces make it particularly useful for discussions and dialogue on water resources management among stakeholders.
