This work focuses on pollution control in the trans-boundary area of Taihu Basin. Considering the unique characteristics of the river network in the study area, a new methodology of pollution control is proposed aiming at improving the water quality in the trans-boundary area and reducing conflicts between up and downstream regions. Based on monitoring data and statistical analysis, important trans-boundary cross sections identified by the regional government were selected as important areas for consideration in developing management objectives; using a 1-D mathematicmodel and an effective weight evaluation model, the trans-boundary effective control scope (TECS) of the study area was identified as the scope for pollutant control; the acceptable pollution load was then estimated using an established model targeting bi-directional flow. The results suggest that the water environmental capacity for chemical oxygen demand (COD), in order to guarantee reaching the target water quality standard in the TECS, is 160,806 t/year, and amounts to 16,098 t/year, 3493 t/year, and 39,768 t/year for ammonia nitrogen, total nitrogen, and total phosphorus, respectively. Our study method and results have been incorporated into the local government management project, and have been proven to be useful in designing a pollution control strategy and management policy.
本研究聚焦于太湖流域跨界区域的污染控制。考虑到研究区域河网的独特特征，提出了一种新的污染控制方法，旨在改善跨界区域水质，减少上下游地区之间的冲突。基于监测数据和统计分析，将区域政府确定的重要跨界断面选为制定管理目标时重点考虑的区域；利用一维数学模型和有效权重评估模型，确定研究区域的跨界有效控制范围（TECS）作为污染物控制范围；然后使用针对双向水流建立的模型估算可接受污染负荷。结果表明，为确保在TECS内达到目标水质标准，化学需氧量（COD）的水环境容量为160806吨/年，氨氮、总氮和总磷的水环境容量分别为16098吨/年、3493吨/年和39768吨/年。我们的研究方法和结果已被纳入当地政府管理项目，并已证明在设计污染控制策略和管理政策方面是有用的。
