| 摘 要： | 简要介绍了水资源管理软件Water Ware中的子模块WRM的原理及其功能,并对其中的水库模型进行了改进.针对水库对生态系统基流的均化影响,提出了均化系数的概念,并且给出了计算方法.利用改进的WRM模块,分别研究了嘉陵江中上游2座及3座水库对基流的累积影响.分析计算表明:2座水库的均化系数为0.29,而3座水库的均化系数则达到0.58,流量均化程度的增大主要是梯级水库累积影响的结果.

| Abstract: | The principle and functions of the WRM Module in advanced software WaterWare are introduced briefly. Reservoir model in the WRM Module has been improved because it isn't fitted to the Yangtze River basin. Moreover, averaging coefficient is defined; and the method for calculation is provided due to the averaging effect of a reservoir on ecological base flow. Based on the improved WRM Module, it is analyzed respectively that two and three reservoirs cumulatively affect on base flow in upper and middle reaches of the Jialing River. The results show that the averaging coefficient of two reservoirs is 0.29, and the averaging coefficient of three reservoirs is up to 0.58. The latter is bigger, which is due to cumulative effects of multi-reservoirs. |
