| 摘 要： | 通过对水曲柳人工幼林的高生长进行定时、定位观测,运用多元分析方法分析了水曲柳幼林的高生长在生长季节内的动态变化,其中,高生长量最大值出现在6月份,占全年总生长量的61.24％;在此基础上,确定了其生长速度的拐点。最后把人工水曲柳幼林的高生长划分为五个生长阶段,即:初生期、缓慢期、速生期、下降期和终止期。

| Abstract: | Based on the time and location observation and measurement on the height growth of young manchurian ash plantation, the seasonal dynamics has been analyzed by using the method of Multivariate Regrcssion Analysis. Then, the knee of growth speed was de termined. At last, five periods such as the primary, the slow, the fast, the fall and the termination were divided for the height growth of young manchurian ash plantation during the growth season respectively. It can provide a scientific basis for young forest manage ment and increasing the bioproductivity. |
