【摘要】 毛竹油桐混交林总生物量比油桐纯林和毛竹纯林分别提高了58.37%和13.11%;混交林内立木平均胸径较明显大于纯林;混交林气温温差较毛竹纯林小,而湿度均较毛竹纯林大,表明混交结构使林内气温稳定,湿度增高,有利于林分生长;混交林对林地土壤养分状况有明显改善,其中有机质含量的增幅最大。更多还原

【Abstract】 The total biomass of mixed forests of Phyllostachys pubescens and Vernicia fordii than pure forests of Phyllostachys pubescens and Vernicia fordii were increased by 58.37% and 13.11%, respectively; the average diameter at breast height of mixed forests trees was obvious greater than the pure forests, temperature difference in mixed forests was smaller than pure forests, humidity was greater than pure forests, and all show that the mixed structure make temperature stable, humidity increased and in favor of stand growth; forest soil nutrient status has significant improvement, of which the organic matter content increase largest.更多还原
