在森林调查中,立木的生长率往往不易直接确定。用高径比法确定立木生长率,不仅外业操作简单,而且测量精度与其它方法相近,可以达到生产的要求。本文以落叶松为例,用高径比对立木生长率进行了测算,取得了较好效果。 In forest surveys, the growth rate of standing trees is often not easily ascertained. The height-diameter ratio method to determine the growth rate of standing wood is not only easy to operate in the field, but also has the same measurement accuracy as other methods and can meet the production requirements. In this paper, taking Larch as an example, the growth rate of standing tree was calculated by height-diameter ratio, and good results were obtained.
