The inter-provincial transboundary area of the Taihu Lake Basin is characterized by a complex river network and reciprocating flow. Frequent environmental pollution events in recent years have become a major safety hazard for the water quality in the Taihu Lake Basin. There are few early warning systems for environmental pollution events in China, the ability to simulate risk is insufficient, and systematic research on technology, development, and application is lacking. Thus, water management requirements are not met in the inter-provincial transboundary area of the Taihu Lake Basin. This paper proposes a cross-border risk management plan for pollution sources in the transboundary areas of the Taihu Lake Basin and an early warning and emergency response system for water pollution events using modern information technology. We used this system to assess and classify 2713 risk sources for nitrogen and phosphorus pollution into 5 categories. We simulated the discharge of a pollutant into a tributary and the early warning and emergency response for the transboundary region. The results indicate that the proposed early warning and emergency response system substantially improved the transboundary water environment and lowered the risk of pollution in the Taihu Lake watershed.
太湖流域省际跨界区域河网密布、水流往复，近年来频繁发生的环境污染事件已成为太湖流域水质的重大安全隐患。我国环境污染事件预警系统较少，风险模拟能力不足，缺乏对技术、开发和应用的系统研究，太湖流域省际跨界区域的水管理需求无法得到满足。本文提出了太湖流域跨界区域污染源跨境风险管理方案以及利用现代信息技术的水污染事件预警与应急系统。我们使用该系统将2713个氮磷污染风险源评估并分类为5类。我们模拟了一种污染物向一条支流的排放以及跨界区域的预警与应急响应。结果表明，所提出的预警与应急系统显著改善了跨界水环境，降低了太湖流域的污染风险。
