| China is the first worldwide citrus production nation, but the per area yield and quality of citrus is less than
thoes of such citrus production nations as USA and Brazil. It爷s urgent to improve the management level of citrus
production, while Digital Orchard is an effective way to achieve exact management. In the paper, firstly, the design
principle, system architecture, main module and critical technology for developing this system were introduced in detail.
The COM based on developing environment-ArcEngine of ESRI and .Net software development platform of Microsoft were
used. The sytems running results showed that accuracy rate of citrus orchard area reached 97.2%, citrus production
estimates outcome of Yilin county, Hubei province reached 84.7%. The deployment of this system has a significant meaning
on improving the management of citrus orchard administrative department, moreover. It can be used as reference for
