【摘要】：以董志塬为研究区,依据地区经济社会状况及发展规划计算水资源需量。选用影响该区水资源供给及利用的三个主要因素(开源、推行节水措施和缩减地下水开采)构造8种水资源配置预案,基于WEAP模型预测董志塬三个规划年的水资源供需状况并进行最佳预案遴选。结果表明:8种配置预案在不同年份供需关系差异较大;考虑台塬区地下水系统健康的减采措施的最佳预案下,2015年(缩减开采)和2020年(缩减开采+节水措施)水资源供需基本达到平衡,2030年(缩减开采+节水措施+基于立地便利的开源)董志塬总体处于缺水状态,供水缺口为1 482万m3。可见,经济社会发展背景下,水资源利用结构发生转变,水资源稀缺地区水资源配置的思路也应该作出相应的调整。从长远来看,积极寻求外调水源是实现黄土台塬区可持续发展的唯一途径。
[Abstract]:Taking Dong Zhiyuan as the research area, the water resource demand is calculated according to the regional economic and social conditions and the development plan. Eight kinds of water resources allocation plans are selected to influence the supply and utilization of water resources in this area (open source, water saving measures and groundwater exploitation reduction). Based on WEAP model, the supply and demand of water resources in three planning years were predicted and the best plan was selected. The results show that the supply and demand relationships of 8 kinds of disposition plans vary greatly in different years. Considering the best plan of reducing mining measures for groundwater system health in Taiyuan area, the supply and demand of water resources are basically balanced in 2015 (to reduce exploitation) and 2020 (to reduce water saving measures), and 2030 (to reduce the basis of mining and water saving measures). Dong Zhiyuan is in a state of water shortage in general. The water supply gap is 14.82 million m3. It can be seen that under the background of economic and social development, the structure of water resources utilization has changed, and the thinking of water resources allocation in water scarce areas should be adjusted accordingly. In the long run, it is the only way to realize the sustainable development of Loess tableland region.
