Results showed that 1 soil structure in the rhizosphere was very high; water-holding capacity and organism count in the soil increased with altitude and duration of bamboo growth. However, soil etiolation and soil acidification was obvious. 2 Soil acidity was adjusted with lime; best applications were 10.625 thm^(-2) on the valley bottom, 14.811 thm^(-2) for the middle slope, and 12.558 thm^(-2) on the valley top.
结果显示：毛竹林根系活动层(60 cm)土壤结构较好，土壤水源涵养功能的大小和土壤的有机质质量分数随毛竹林成林时间和海拔高度的增加而增加；但土壤黄化、酸化特征较明显，土壤酸性调节主要以施用石灰为主，其中谷底毛竹林改造需石灰量为10.625 thm^(-2)，坡面的里白毛竹林为14.811 thm^(-2)，岗地毛竹林需石灰量为12.558 thm^(-2)；在氮磷钾3种元素中，氮素供应总体上良好，但要获得高产，氮肥的补充也是必需的。
