由于不同水源汇入及分出等的交替作用与影响,多水源、多用户联通构成的多元汇入和分出的输调水系统运行是水量、水质混合及时空演变的过程,为量化不同节点及引出目标的水源构成和水质指标时变状态,研究建立了多元输调水系统动态水指标... 由于不同水源汇入及分出等的交替作用与影响,多水源、多用户联通构成的多元汇入和分出的输调水系统运行是水量、水质混合及时空演变的过程,为量化不同节点及引出目标的水源构成和水质指标时变状态,研究建立了多元输调水系统动态水指标解析模型。模型以输水系统干网和各汇入、分出口及调蓄工程为研究范围,以沿程实时水量组成、水质因子为研究对象,提出系统多元动态水量与水质指标解析计算方法。以南水北调中线总干渠河南段为示例,应用模型得到干渠各节点、分出口的各水源水量构成、水质因子等指标成果,经分析可为制定科学合理的调度方案、实现预报预调或水量统计核算提供技术支撑,从而提高多水源联合调度的管理水平。 展开更多

China is one of the countries most severely suffering from tropical cyclones. The exact and timely forecasting and warning is of significant importance in fighting against tropical cyclones and mitigating their impacts on China. The numerical weather prediction (NWP) system for tropical cyclone rainfall and strong wind is going to play a more and more important role. There is also a need for timely and user friendly modem warning services in order to provide the governments and relevant authorities at all levels and general public with typhoon forecasts and information about the associated disasters and response strategy services. 展开更多
