在泰安地区大汶河沿岸,刺槐林面积为21837.9亩,占有林地面积的23.9％。为加强经营管理和抚育改造这部分林子,以及今后造林达到适地适树,我们根据大汶河沿岸低产林分改造调查资料,编制了刺槐林立地质量数量化表。 立地质量数量化表也称多因子数量立地质量评价表。是以环境因子为依据预测林地质量的数表。本表根据数量化的立地因子与树高生长相关关系所建立的多元线性回归方程而编制的,其方法步骤如下。
Dawn in the Tai’an area along the coast, the acacia forest area of 21,837.9 acres, accounting for 23.9% of the area of forest land. In order to strengthen the operation and management and raise and rebuild this part of the forest, and to achieve the appropriate afforestation in the future, we compiled the quantitative table of the quality of the locust forest based on the survey data of the low-yield stand transformation along the Dawen River. Site quality quantitative tables, also known as multi-factor site quality evaluation form. Is based on environmental factors to predict the quality of woodland tables. This table is based on a multiple linear regression equation established by a quantitative relationship between site factors and tree height growth. The method steps are as follows.
