AN INITIAL STUDY ON EFFECT OF YOUNG STANDS OF INTRODUCED SPECIES BY QUANTITATIVE COMPREHENSIVE EVALUATION

In order to evaluate the effect of tree introduction promptly, micro-computer has been adopted to mark various factors and to process data, in which the programe language is extended BASIC. 10 factors of young plantations of 90 tree species aging from 3 to 7 years old, such as height, annual average growth of DBH, suited situation etc., have been investigated and marked. The results show that all the species can be graded into 6 classes, among them 7 and the other 25 tree species are respectively recommonded as planting or disseminating ones there.
