Abstract: The author summarized the methods of study and the system of the index about the drought resistance. It is concluded that there are two main kinds of methods in studying the drought resistance of trees: 1) Studying the physiolo-gical-biochemical index, 2) Studying the form and constructure of trees. Index:moisture content index of leaves, photosynthesis index, enzyming activity and protoplasm index, hormone index, the dissectedy constructure of leaves, and biomass index. And the author put forward the further study on the problems which rceed deal with on the above expects.

Key words: TREE SPECIES, DROLGHT RESISTANCE, STLDY METHODS, INDEX SYSTEM, MOISTURE CONTENT
