在雷州林业局的10个林场,按三个不同立地条件,不同生长类型的林分,典型选取样木707株,分径阶按二米区分段实测,分别选用幂函数方程、一元一次方程,进行回归演算,分剐编制雷州尾叶桉人工林(实生)立木二元材积表与一元树皮率表。
In 10 forest farms of Leizhou Forestry Bureau, 707 samples of typical wood were chosen according to three different site conditions and different growth types. The measured diameter was measured by two meters in different stages. The power function equation, The regression calculus was divided into 立 compilation of eucalyptus urophylla plantation (real) standing tree birch volume table and a bark rate table.
