摘要
以淮河干流和主要支流沙颍河为研究区域,在现有水质监测站网和监测频次的基础上,结合水量变化过程分析水质的时空分布规律,探讨分质水量的综合评价方法。以研究区域的水质、水量和污染源资料建立水质模型(Mike11-WQ),用模拟的水质过程与实测水量结合评价分质水资源量;对比逐日水质资料与不同监测频次(每月1次和每旬1次)的实测水质资料,分析分质水量评价的精度与可行性;通过不同方法的应用效果分析与比较,对有关问题进行讨论。
Based on the existing water quality monitoring network and monitoring frequency in the study area of the Huaihe River mainstream and its main branch Shaying River, water quality variation on time and space was analyzed in combination with the water quantity changes, and an integrated assessment method for water quantity with different qualities was put forward. A water quality model (Mike 11-WQ) was established based on the field data of water quality, water quantity and pollution sources in the regions. Water resources with different qualities were evaluated according to the simulated water quality data and the measured water quality data. Accuracy and feasibility of the method were analyzed through the comparison between daily water quality and measured water quality data in different monitoring intervals (once every month and once every three months). Problems concerned were discussed based on the comparison and analyses of results obtained by different methods.
