| 摘 要： | 天然幼中龄林立体经营试验结果表明:乔——药立体经营模式每公顷年可获纯利润5 037元,乔——藤立体经营模式每公顷年预测纯利润6 595元;试验林分目的树种的胸径和材积年平均生长量分别比对照地林木年平均生长量提高了131.3%和132.9%;主要目的树种的比例增加,林分质量和生产力得到改善和提高,达到了对天然幼中龄林科学经营、培育后备森林资源的预期目的。

| Abstract: | The diversification trial to natural young middle-aged forest shows that a tree-medicinal plant model can win the net profit for 5037 yuan per hectare,and 6595 yuan per hectare for the tree-liana.Compared to the trees in check plot,the experimented goal tree species have enhanced131.3% and 132.9%in diameter at chest height and mean annual volume increment,separately.Owing to increase of proportion in main objective species,the productivity and quality of forest-land have been improved and enhanced,achieved science management to the natural young middle-aged forest,attained anticipated goal for cultivating reserve forest resources. |
