摘要：在中国林业科学研究院热带林业实验中心28年生人工红椎纯林、马尾松纯林和红椎＋马尾松混交林内，设立标准地，通过在0—60cm土层取样，测定土壤容重、总孔隙度及其各层土壤养分含量与储量，分析土壤理化性状及其养分含量变化特征。结果表明：红椎＋马尾松混交林林地表层（0—20Cm）土壤容重、总孔隙度明显好于红椎纯林和马尾松纯林（P〈0．05）；红椎＋马尾松混交林各层土壤养分（有机质、氮、磷和钾）含量以及土壤层（0～60cm）养分储量高于马尾松林；但红椎＋马尾松混交林与红椎纯林之间在各层养分含量、土壤层养分储量的差别各异。总体而言，红椎＋马尾松混交林对土壤理化性状的改善作用优于马尾松纯林和红椎纯林。
By measuring soil bulk density, total porosity, nutrient content and nutrient reserves of soil samples taken from 0 - 60 cm soil layer, the change of soil physical and chemical properties of the 3 28-year-old forest plantations of pure Castanopsis hystrix （CH）, pure Pinus massoniana （PM）, and mixed C. hystrix and P. massoniana （mixed CH/PM） were studied at the Experimental Centre of Tropical Forestry, Chinese Academy of Forestry. The results showed that the bulk density and total porosity at top-soil horizon （0 - 20 cm ） of the mixed CH/PM were significantly better than those of CH and PM （P 〈 0. 05）. The nutrient （organic matter, nitrogen, phosphorus, and potassium） concentration in various soil horizons or nutrient storages in soil horizon （0 60 cm） of mixed CH/PM were higher than those of PM; however, the difference of those chemical indicators between mixed CH/PM and CH changed according to different conditions. In generally, mixed CH/PM was better than PM and CH in improving soil physical and chemical properties in south subtropical area of China.
