南水北调中线工程水源区生态环境问题非常突出，依据GIS理论，建立一体化的信息监测平台，有利于水源区生态环境保护。在研究GIS在水源区生态环境监测中的应用基础上，对水源区生态环境监测体系的构建进行了研究，包括监测思路对策研究、监测指标体系构建研究、监测体系平台结构设计研究、监测体系平台日常应用研究等，重点对监测体系平台进行了详细的阐述。系统按照应用逻辑自上而下分为应用层、中间层、数据层以及远程监测层；监测体系平台采用了B/S和C/S结构相融合的模式构建，平台功能结构设计了八大数据库和六大应用子系统。

The ecological environment of the water source area of the middle route of South-to-North Water Diversion Project has outstanding issues, and the construction of integrated information monitoring system platform based on GIS is beneficial for the ecological environment protection of the water source area. Based on the study of application of GIS in the ecological environment monitoring, the construction of ecological environment monitoring system of water source area includes the following aspects: the countermeasures of ecological environment monitoring, construction of monitoring index system, design of monitoring system platform structure, and daily application of the monitoring system platform, and the monitoring system platform is illustrated in details. The system can be divided into four layers from top to bottom according to the application logic, including the application layer, intermediate layer, data layer, and remote monitoring layer. The monitoring system platform adopts the model construction of the combination of B/S and C/S structures. The platform function structure has eight databases and six application subsystems.
