茶坊位于延安北部杏子河下游,属于黄土丘陵沟壑区,梁峁坡陡,沟壑切割较深,植被稀疏,水土流失严重,因此黑垆土残留不多,目前以不同黄土母质发育成的幼年土壤如黄绵土、二合土、硬黄土、红胶泥等为主。 The tea plantation is located in the lower reaches of Xingzi River in the northern part of Yan’an. It belongs to the loess hilly and gully area. The steep slope of the slope, the deep gully cutting, the sparse vegetation and the serious soil erosion cause that there are not many residues of black mound. At present, young soil developed from different loess parent materials Such as loess, loess, hard loess, red clay mainly.
