Abstract

To cope with the system efficiency problems caused by mass-data and the centralized management in the forest resources database, the paper analyzed the spatial data management mechanism of ArcSDE spatial engine and worked out the optimization strategies for Oracle DBMS based spatial database system from four perspectives including database design, DBMS configuration, ArcSDE configuration and database maintenance. The provincial level forest resources spatial database of Fujian Province was taken as an example to validate the main optimization strategies. The results indicated that the rational adjustment of the parameters of DBMS and ArcSDE engine（Oracle SGA size, ArcSDE index size and MAXBUFSIZE）, optimization of the database design and adoption of the middle table technique could all improve the query efficiency significantly. For optimizing forest resources database, efficient logical database structure and distributed physical database structure should both be considered. ［Ch, 5 fig. 1 tab. 12 ref.］
