补充资料：亚高山灰化土
亚高山灰化土
仅分布于贡嘎山东坡海拔3300－3600米的冷杉林下。气候冷、湿多云雾。冷杉 (abies fabri、 a. faxoniana) 和杜鹃、箭竹等高度郁闭。地被苔藓层深厚，土壤长期处于冷、湿环境下，针叶残落物因真菌活动而酸化，并随雨水下渗将土壤中盐基淋溶，在灰化层下是棕色的淀积层。呈核状或棱块状结构，常有铁结核和铁沾磐。土壤质地沾重。成土母质为冰碛物、残积物。土层较薄，往往在灰化层下即有大量角栎，一般约在45厘米以下即为未风化之粗骨质，系由花岗岩砾石构成的冰碛物。土壤呈强酸性反应，ph值3.7－4.3左右。土体有机质含量少，因此，亚高山灰化土肥力低。加之环境冷湿，所以，森林一旦被破坏，恢复和更新极困难。
