In order to obtain the river system space distribution and river system feature information of the Lijiang River Basin, the authors, with Google Earth images as information source and by using the method of man-machine interactive visual interpretation, extracted basin river system configuration information and compiled water distribution map of Lijiang River basin. On the basis of information extraction and statistics of such factors as the water level, drainage density, stream tributaries branching ratio, length, and intersection angle, the morphological characteristics of Lijiang River Basin system was quantitatively demonstrated. An analysis of control factors based on river system morphology characteristics revealed that the strata and faults are the important controlling factors of Lijiang River morphology, and that the influence of human activity is growing. The research results provide objective scientific basis for the Lijiang River comprehensive control and treatment and also fill the blank in the study of the Lijiang River basin landform.
