【摘要】 为简便而又迅速的评价出林木引种的成效,采用“多元评分,微机处理”的方法,利用扩展Basic语言编制程序,对林科院大岗山实验局的包括3至7年生的90个树种的人工幼林,通过树高、胸径年均生长量调查及适生表现等10项指标进行积分统计,归并成6个等级。其中推广造林树种7种,推荐造林树种25种。更多还原

【Abstract】 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.更多还原
