摘要
本文通过在一个县级区域一定时期内对林木的高、径生长作连续跟踪调查,得出当地马尾松、湿地松、杉木人工纯林及阔叶天然纯林等几种典型林分的树高、胸径、立木蓄积量的生长量和生长率。这为本区及周边邻近地区相似林分和立地条件的林分生长量、生长率指标的使用提供了一定的参照依据。
Currently the growth rate index of a certain tree species is referred to the average value on the basis of provincial area, and this usually results in the calculation error for specific locations. In this study, consecutive investigation of the tree growth rate was carried out for a certain period in a smaller area at the county-level, and as the result, the growth rate of the tree height, DBH, and tree volume of several typical forest types were obtained, including artificial pure forests of masson pine, slash pine, Chinese fir, and natural pure forest of broad-leaves. The results are applicable for the study area and its neighboring areas which have similar forest types and site conditions.
