In this paper we discuss the topological entropy of a tree map and obtain several equivalent conditions for a tree map with positive topological entropy.

本文讨论树映射的拓扑熵，得到树映射具有正拓扑熵的几个等价条件。

Furthermore, we also obtain a few equivalent conditions which a tree map is strongly not-chaotic and a few equivalent conditions which a piecewise monotone tree map has topological entropy zero.

此外，还得到了树映射是强非混沌以及逐片单调树映射的拓扑熵为零的几个等价条件。
