摘要：

The feasibility of using a nuclear method to make non-destructive measurements of both fresh canopy mass and canopy surface-water storage was examined. The theory of .gamma.-ray attenuation was developed for the field situation and a preliminary experiment is described in which the accuracy of the canopy mass estimate is verified by comparison with a destructive measurement. By artificially saturating the canopy with water, a canopy storage capacity of 2.4 .+-. 0.6 mm was estimated for Sitka spruce of average height 12 m.
