摘要
本文应用灰色系统理论中的关联度分析方法,定量地分析了加拿大杨插条苗和刺槐播种苗苗期高生长量与气候因素的关系。结果表明:气候因子对两种苗木高生长量的影响效应基本一致,其主导因子均为水分状况,从而为苗期的科学管理提供了量化的理论依据。
The connection degree analysis of Grey system theories was applied to the quantitative analysis of the relationship between the climatic factors and the height increment of Canadian poplar rooted cuttings and locust seedlings. The result showed that climatic factors on height growth appeared roughly eaqual for the two species.And the domo-nant factor was the rainfall.This conclusion provided the scientific nursery management with a quantified theoretical basement.
