The design, implementation and application of the seawater quality variable fuzzy evaluation system based on ArcEngine

The variable fuzzy evaluation method was introduced to the seawater quality assessment,and a variable fuzzy evaluation system of seawater quality was designed and established on the basis of ArcEngine.The data was obtained by accessing the seawater quality assessment database in SQL Server through the ArcSDE data engine and special development interface.The variable fuzzy mathematical mode was combined with GIS spatial technology in Visual C# 2008 development environment.By using ArcEngine integrated development technology,the result of seawater quality evaluation was visualized.This system provided technical support for the environmental planning and pollution control.
