摘　　要：选取台州市东官河作为浙江温黄平原典型河流的代表,构建MIKE11河网水环境数学模型,基于水量、水质同步实测数据对模型进行率定验证。为保证东官河控制断面水质达标,综合考虑水文条件、污染物削减和引水3个方面因素,提出了9套研究区域模型计算方案。结果表明,近期区域内污染物削减60%,控制长潭水库调水量为2 000万m3时,东官河水质可达Ⅳ类;远期区域内污染物削减90%时,东官河水质基本可达Ⅲ类即功能区水质目标。本研究旨在为东官河水环境综合整治提供技术支撑。In this study, the Dongguan River in Taizhou City was selected as a typical fiver of the Wenhuang Plain, in Zhejiang Province. The MIKE11 water environment mathematical model was established, and then calibrated and validated based on simultaneously monitored data of water quality and quantity. In order to ensure that the water quality in the control section of the Dongguan River would reach the standards, nine schemes for model calculation in the research area were used with comprehensive consideration of hydrologic factors, pollutant reduction, and water transfer. According to the results, in the recent period, as the proportion of pollutant reduction reached 60% , and the amount of water transferred from the Changtan Reservoir reached 20 million cubic meters, the water quality of the Dongguan River reached the grade Ⅳ level. For a long period, as the proportion of pollutant reduction reached 90% , the water quality of the Dongguan River almost reached the grade Ⅲ level, meeting the functional area requirement. This study aims to provide technical support for comprehensive environmental improvement of the Dongguan River.
