摘　　要：为提高毛竹林的生物生产力，在广西资源县中峰乡选择不同经营管理措施毛竹人工林设置土壤剖面和取样，按国家颁布标准测定其土壤理化性质。结果表明：（1）0．-40cm土层的土壤密度为0．735-1．14g·cm^-3；土壤总孔隙度为44．85％～58．56％；土壤通气度为30．7％～55．4％；土壤最大持水量、毛管持水量和最小持水量依次为53．87％-92．02％、37．05％-62．49％和21．21％-34．23％。（2）O。40em土层的土壤pH值为4．62～4．90；土壤有机质含量为16．78—79．37g·kg^-1，土壤全N、全P、全K含量依次为1．18～4．01g·kg^-1、0．94～1．91g·kg^-1。和22．48～42．26g·kg^-1。（3）全垦抚育方式的土壤密度比不抚育方式略小；土壤孔隙度及持水量比不抚育方式略大；土壤有机质及N、P、K养分含量比不抚育方式略高。研究结果充分说明，该区毛竹林地土壤疏松、通气、透气性能良好，土壤酸减度适中，土壤有机质以及N、P、K养分含量较高，这些研究结果为该区毛竹人工林的经营管理与评价提供了重要的参考价值。To improve the biological productivity of Moso stands, the soil physical and chemical properties of bamboo groves at different sites in Zhongfeng Township, Ziyuan County, were measured according to the national standard. The results showed that： （1） The soil density（0 -40 cm layer） was 0. 735 - 1.14 g ·cm-3, the total soil porosity was 44. 85% - 58.56%, the soil aeration degree was 30. 7% -55.4%. The maximum soil water holding capacity, the capillary water holding capacity and the minimum water holding capacity were 53.87% - 92. 02%, 37.05% ~ 62.49% and 21.21% - 34.23% respectively. （2） The soil pH value （0 - 40 cm layer） was 4.62 - 4.90, the soil organic matter content was 16.78 ~ 79.37 g·kg^-1. The soil full N, P, and K contents were 1.18 -4. 01 g·kg^-1 , 0.94 - 1.91 g·kg^-1 and 22.48 -42.26 g·kg^-1 respectively. （3）In comparison with the non-tending bamboo stands, the soil density of bamboo stands under tending were slightly smaller, the soil porosity and water holding capacity were slightly larger, the soil organic matter and N, P, K nutrient content were slightly higher. This demonstrated that in the area under study the soil were loose, soil permeability were good, the soil DH value were moderate, the soil organicmatter and N, P, K nutrient content were high. The results may provide important reference for the regional bamboo plantation management.
