Abstract
Heterogeneity of operation system, data storage system and semantic data in forestry science data-sharingenvironmentwas analyzed. At the operation system level, a service-oriented architecture of forestry science data-sharing system was made so that the distributed data access was realized between diverse operation systems andapp lication p latforms smoothly; at the data storage level, a design pattern-oriented data access component hasp rovided a unified access means for different database and data file; at semantic level, the common data elementdirectory eliminated semantic heterogeneity, which realized automatic data converting. This paper also pointed outtechnological trend of forestry science data-sharing in the future.
