摘要
通过对河道水面蒸发量、渗漏量、漫溢量的分析,建立了以月为单位的塔里木河干流河道水均衡模型.该模型以阿拉尔来水量为输入,输出包括干流主要水文站点的水量、各河段的蒸发量、渗漏量、漫溢量等.利用1981—1995年逐月的水文资料进行了模型参数率定,以1996—2000年的水文资料进行了模型验证,结果表明模型具有较好的适应性.利用该模型分析塔里木河干流水资源转化消耗的规律,得出河道漫溢尤其是中游的漫溢是塔里木河干流主要的水量消耗.考虑堤防建设对模型进行了修正,并利用修正后的水均衡模型分析了堤防建设的影响.
A monthly water balance model of the Tarim River mainstream is established based on the analysis of river discharge, evaporation, seepage and overflow. The model input is the river discharge at Alar, and the output items include the discharges of some stations along the mainstream, and evaporation, seepage and overflow of each river section. The model parameters are calibratedwith the data from 1981 to 1995, then the model is validated with the data from 1996 to 2002 and the result indicates the model works well. With the model, the water transportation and consumption along the Tarim River mainstream is analyzed, and overflow is identified as the main consumption item. Finally the model is further modified to estimate the effect of the embankment construction.
