摘要：It is an important question to calculate number of grown branches in a tree in visualization of trees growth. The number of growth branches is determined by visual effect or developer′s experience. This paper overcomes disadvantages of branches calculation by man-made factors, and proposes an algorithm to calculate number of branches belonged to a tree based on extend square root principle of fractal. It is a result of cartography combination with math, forestry and computer graphics. This method can calculate number of a tree's branches after growing based on the tree heights before and after growing period of time, the number of a tree's branches before growing period of time, and the tree branches fractal. The paper offers deducing procession and application example of the expressions. It can be used in spatio-temporal GIS and in visualization of plant's growth especially tree's growth
