Abstract:Abstract：The space Remote sensing technology is widely used now in forest investigation and planning, especially in the identification of tree species. Here we choose Tamarindus Indica L., a broadly distributed tree in Jinshajiang River basin as the object, in combination with field survey results and 3D interpretation, the authors analyze and establish its interpretation features in different biotopes, and then interpret the aerial photos of this species. The authors provide certain experience for the tree species interpretation of the aerial photos in Jinshajiang River basin.
