数量化方法(Ⅰ)是随着电子计算机的广泛应用而发展起来的对质的因子进行数量化的方法。林业上早已用于数量化林分蓄积量表的编制。目前不少国家、国内不少省份采用数最化理论(Ⅰ)对立地质量进行评价,一方面可直接定量地给出了各个因子对林木生长的单独作用。它不仅对有林地可以进行预估,而且对于即将造林的无林地也能进行预估。 The method of quantification (I) is a method of quantifying qualitative factors developed with the widespread use of electronic computers. Forests have long been used in the preparation of quantitative forest stocking scale. At present, many countries and many provinces in China use the most number theory (Ⅰ) to evaluate the site quality. On the one hand, it can directly and quantitatively give the individual effect of each factor on the growth of trees. Not only can it be estimated for forested land, but it can also be estimated for the forested area.
