太行山区峰峦层叠,十年九旱,土壤瘠薄,给人工造林带来很多困难,尤其是在占山地总面积一半以上的劣质立地上造林,困难更甚。近年来,我场根据劣质立地的自然特点,采取抗旱造林的方法,取得了一些效果。一、劣质立地的自然特点划分立地类型是科学造林的依据。石质山区立地类型是根据海拔、坡向、土层 There are many mountainous areas in the Taihang Mountains, with ten years of nine drought and infertile soils, which bring many difficulties to artificial afforestation. In particular, it is even more difficult to afforestation on inferior sites that account for more than half of the total mountain area. In recent years, based on the natural features of poor quality sites, our field has taken some measures to combat drought and afforestation and achieved some results. First, the natural characteristics of poor site classification Site type is the basis of scientific afforestation. Stony mountainous site type is based on elevation, aspect, soil
