摘要
研究针对中国小型岛屿地区的淡水资源短缺问题,以提高水资源的利用效率为核心。研究目标涵盖构建来水和用水预测模型,开发针对水库运行的数学模型,并着重于水资源管理的优化。以浙江省岱山县为案例,阐述调度方法在减少弃水率和提高水资源利用效率方面的量化效果。研究结果表明,岱山县在3月份的空库系数最低(0.738),而水库群平均蓄水率达到67.19%。研究提出的调度方案显著减少了弃水量,并提高了水量利用系数和灌溉保证率。研究为解决小型岛屿地区以及其他水资源匮乏地区的淡水短缺问题提供一个高效的新视角和可行性方案,为推动水资源管理的可持续发展提供参考。
Addressing the pressing issue of freshwater scarcity,particularly in island regions of China,a study was conducted on scheduling methods aiming at enhancing water resource efficiency.The main objectives of the study involved the creation of inflow and water usage prediction models,the development of a mathematical framework for reservoir operations,and the optimization of water resource management.A case study focusing on Daishan County in Zhejiang Province,China,was utilized to quantify the effects of the implemented scheduling methods on reducing water wastage and improving water resource utilization.Findings revealed that the lowest empty reservoir coefficient in Daishan County was 0.738 in March,with an average reservoir storage rate of 67.19%.The scheduling approach significantly mitigated water wastage,elevated the coefficient of water usage and improved the irrigation assurance rate.This study offers an efficient solution for alleviating freshwater shortages in islands and other water-scarce regions,thereby contributing to the sustainable development of water resource management.
