摘要
根据对３００多个四合木基茎的测量和对四合木年轮宽度与降水、气温的相关分析，可以得出如下结论：四合本营养生长和气候因子有明显的相关关系，其中全年总降水量与四合本营养生长的关系最为显著．这表明水分是制约四合木营养生长的主要因子．但四合本营养生长受到降水、气温的综合影响．四合本年轮宽度和全年降水量、年均温的二元回归方程不但相关系数最大，而且各项系数检验均为显著，具有较为可信的二元回归方程；ＮＡＬ＝８．６０＋０．０１０８ＰＡ－０．
Based on the measurement of more than three hundreds Tetraena mongolica main stems and the analysis on correlation coefficients between rings' width and precipiction、temperature, conclusions can be drown as follows:There are significantly correlativities between rings width and climatic factors which between rings' width and the total of precipiction is the most significant. It indicates that water is main limitation in Tetraena mongolica growth. However the influence of climatic factors is comprehensive. The two elements' equation of regression of average of rings'width and precipiction、temperature has the biggest correlation coefficient and coefficients of each equation are significant in statistics' tests. So the equation is reliable which is NAL=8. 60+0. 0108PA-0. 0498TA.
