摘    要:本研究以豫西日本落叶松引种区143块标准地及配套的5l株解析木资料,以及与此对应的土壤样品和气象等资料为研究材料,采用计算机程序模拟了优势水平均高对立地因子的数量化回归模型、年轮指数对气象因子及优势木高对土壤理化性状的最优回归模型.通过对三种数学模型的模拟,筛选出该引种区影响日本落叶松生长的主要环境因子为海拔高、冬春季气温及6~7月份降雨、土壤全氮及速效磷,并以此指导生产,避免盲目推广所造成的损失.

关 键 词:日本落叶松  环境因子  数量化回归模型1  年轮指数  逐步回归  多元线性回归

Abstract:Based on the materials of 143 standard plots in Larch-tree introducing area and over 5O analytical their trunks,and the corresponding analysis data of the soil samples and climatic data in the mountain area of western Henan,The mathematical regression model between the optimun regression models,annual ring index and climatic factors as well as dominant tree height and physiochemical properties of the soil were worked out by means of computer programs in the study.The principal environment factors affecting the growth of Larch-tree were screened in the introducing area by drawing up three mathmatical models,They were elevation,the atmospheric temperature in spring and winter,the precipitaton in June and July,total nitrogen and available phosphorus.Which were good for directing production and avoiding from blindly introducing and popularization,the gratifying economic benefits were obtained.
Keywords:Larch-tree  environment factor  mathematical regression model  annual ring index  step-by--step regression  multiple linear regression
