The invention discloses a remote sensing surveying method used for estimating the urban tree coverage rate with high precision and a remote sensing surveying system thereof. The method comprises the following steps: S110, a multispectral remote-sensing image is utilized to carry out the partition aiming at extracting crown coverage areas; S120, aiming at the image areas generated by the partition, a fuzzy classifier is built to carry out the tree coverage classification of oriented objects; S130, the precision evaluation of the classified result is carried out; and S140, the urban tree coverage rate is calculated according to the classified tree coverage area. According to the invention, the actual crown ground cover area which is accordant with each tree in an urban area is extracted from the remote sensing images with high resolution, then the total area of the tree coverage in the urban area is calculated according to the pixel ground resolution of the remote sensing images, and finally, the tree coverage rate in the urban area is obtained. Compared with a tree coverage rate calculating method applied currently, the invention has the advantages that the estimation precision is obviously improved, and the actual position of the crown layer ground coverage area of each tree can be obtained.
