There are many watercraft and production accidents in the Three Gorges Reservoir Area (TGRA) of the Yangtze River in China every year. Accidents threaten the water quality of the 1085 km2 surface area of the TGRA and millions of local people if oil and chemical leakage were to occur. A water pollution management system for emergency response (WPMS_ER) was therefore designed for the management of pollution in this area. An integrated geographic information system (GIS)-based water pollution management information system for the TGRA, called WPMS_ER_TGRA, was developed in this study. ArcGIS engine was used as the system development platform, and Visual Basic as the programming language. The models for hydraulic and water quality simulation and the generation of body-fitted coordinates were developed and programmed as a dynamically linked library file using Visual Basic, and they can be launched by other computer programs. Subsequently, the GIS-based information system was applied to the emergency water pollution management of a shipwreck releasing 10 tons of phenol into the Yangtze River during two hours. The results showed that WPMS_ER_TGRA can assist with emergency water pollution management and simulate the transfer and diffusion of accidental pollutants in the river. Furthermore, it can quickly identify the affected area and how it will change over time within a few minutes of an accident occurring.
中国长江三峡库区（TGRA）每年都有许多水上船舶和生产事故。如果发生石油和化学品泄漏，这些事故将威胁到 TGRA 1085 平方公里的地表面积和数百万当地居民的水质。因此，为了管理该地区的污染，设计了一个用于应急响应的水污染管理系统（WPMS_ER）。本研究开发了一个基于综合地理信息系统（GIS）的 TGRA 水污染管理信息系统，称为 WPMS_ER_TGRA。ArcGIS engine 被用作系统开发平台，Visual Basic 被用作编程语言。水力和水质模拟模型以及贴体坐标系的生成被开发并使用 Visual Basic 编程为一个动态链接库文件，可以由其他计算机程序启动。随后，基于 GIS 的信息系统被应用于一起沉船事故的应急水污染管理，该事故在两小时内向长江中释放了 10 吨苯酚。结果表明，WPMS_ER_TGRA 可以协助应急水污染管理，并模拟河流中意外污染物的迁移和扩散。此外，它可以在事故发生后的几分钟内快速识别受影响区域以及该区域随时间的变化情况。
