中文摘要 2006年，在杉木采伐迹地上分别营造毛竹红椎混交林及毛竹和红锥纯林，各林分管理措施基本一致，12年后对比分析混交林与纯林的生长效果。结果表明：毛竹红椎混交林可形成复层的林分结构，林分空间利用率高，混交林各组成树种的生长状况均优于纯林，混交林的林分生产力达到68.91 m³/hm²，分别较毛竹和红锥纯林提高13.94%和43.50%；混交林的林分土壤性质得到明显改善，土壤容重降低，孔隙度和持水量显著增加，土壤有机质及氮、磷、钾含量均优于毛竹和红锥纯林。毛竹红锥混交经营模式值得在生产上推广。

英文摘要 In 2006, the mixed forest of Phyllostachys pubescens and Castanopsis hystrix, and the pure forest of Ph. pubescens as well as C. hystrix were established on the slash land of Chinese fir, and managed with the basically similar measures. The growth effects of mixed forest and pure forests were compared and analyzed 12 years later. The results showed that the mixed forest could form a multi-layer stand structure with high utilization rate of stand spaces; the species growing in the mixed forest showed better growth condition than their counterparts in the pure forests, and the productivity of the mixed forest reached 68.91 m³/ha, higher by 13.94% than the pure forest of Ph. pubescens and by 43.50% than the pure forest of C. hystrix; the soil property in the mixed forest has been evidently improved: the soil bulk density decreased, the porosity and water retention significantly increased, and the content of soil organic matter as well as nitrogen, phosphorus and potassium were higher than those in the pure forests. The Ph. pubescens as well as C. hystrix mixed forest management model is worthwhile to be promoted in production.
