Abstract: To study the precision of calculating forest land area and forest volume , lands of different areas and regular shapes were tested with real-time differential GPS (RTD GPS).The relative errors , variances and precision of the surveying results were calculated and analyzed .The results showed that the minimum surveying precision was 97.67 %, which could satisfy the precision demand for forest land area surveying in the study of various forest resources.With the increase in surveying area , the surveying precision of RTD GPS tended to improve .However , RTD GPS had its defect because the surveyors had to conduct on-the-spot survey , which was impractical for the survey of forest land of a large area .According to the actual analysis of forest land survey , RTD GPS is applicable to the precision test of the traditional survey of forest land area .It is more rapid and efficient than the traditional testing method and can ensure the precision .[ Ch , 1 fig .2 tab .8 ref .]
