调查范围内的各主要树种的蓄积年生长量测定属林分生长量测定范畴,其重要意义在于为确定合理的采伐量提供科学依据。测定林分生长量较为常用的方法有材积表法、标准木法和固定标准地法。但是这些方法具有很大的局限性,尚有待于研究一种简捷而准确的林分生长量测定方法。为此我们对广西高峰林场界牌分场杉木蓄积年生长量的测定方法进行了初步探讨。
The measurement of annual growth of major tree species within the scope of investigation belongs to the category of measurement of stand growth and its significance lies in providing a scientific basis for determining the reasonable harvesting volume. Determination of stand growth methods are more commonly used methods of volume chart, standard wood method and the fixed standard method. However, these methods have great limitations, yet to be studied in a simple and accurate method for determination of stand growth. To this end, we conducted a preliminary study on the determination of annual growth of Chinese fir seedlings at the Licensing Branch of Gaofeng Forest Farm in Guangxi.
