摘要：天然林被人工林取代后对土壤水文物理性质及土壤碳贮量有重要的影响。文章以海南天然次生林人工更新为尾细桉（Eucalyptus urophylla×E．tereticornis）和马占相思（Acacia mangium）林前后的土壤为研究对象，研究分析了人工植被更新对土壤水文物理性质和土壤碳贮量的影响。结果表明：天然次生林更新为桉树、马占相思人工林后，土壤容重增加，土壤总孔隙度、毛管孔隙度和非毛管孔隙度减小，0～80cm土壤的最大贮水量、毛管贮水量和非毛管贮水量降低，桉树和马占相思人工林最大贮水量分别降低19．8mm和43.3mm，桉树人工林0-40cm土壤碳贮量降低6．77t．hm^-2，马占相思人工林的增加14．68t·hm^-2。
The regeneration that the natural secondary forest is replaced by the plantations has a very important effect on the soil physical properties and carbon storage. The effect of natural secondary forest and its artificial regeneration as Eucalyptus urophylla ×E. tereticornis and Acacia mangium plantations on the soil physical properties and soil carbon storage in Hainan Island, China is studied in the paper. It indicates that the soil bulk densities increase and the porosities （total, capillary and non-capillary porosity） decrease and the soil maximum, capillary and non-capillary water-holding capacities in the depth of 0-80 cm also decrease after the natural secondary forest is replaced by E. urophylla ×E. tereticornis and A. mangium plantations. The maximum water-holding capacity is lower 19.8 mm and 43.3 mm respectively in the E. urophylla ×E. tereticornis and A. mangium plantations than the natural secondary forest. The result also showed that the soil carbon storage in the depth of 0-40 cm reduces 6.77 t·hm^2 in the E. urophylla ×E. tereticornis plantation than the natural secondary forest and increases 14.68 t·hm^2 in the .A. mangium plantation than the natural secondary forest.
