| Abstract: |
| 【Objective】This study aimed to establish a risk assessment system for accidental water environment pollution in Three Gorges Reservoir Region,providing decision support for water pollution accident risk assessment in Three Gorges Reservoir Region.【Method】Through the effective integration of GIS and Silverlight,the overall design,function design and key technologies of the system were studied.Then,the risk assessment system of accidental water environment pollution in Three Gorges Reservoir Region was built using B/S as architecture and using Microsoft Visual Studio 2010 and ArcGIS Server 9.3.1 as the platform.The application examples of the system were analyzed as well.【Result】Based on the key technologies including risk source classification method,the sensitive target classification method and risk zoning method,the Three Gorges reservoir water accident environment pollution risk assessment system with the data query and management,risk source and the sensitive target classification and assessment,risk zoning assessment,and other spatial aided decision making functions was established.It met the customer’s basic needs.【Conclusion】The established system achieved the basic GIS function and risk assessment function.It also had good feasibility and practicality. |
