摘要
从 1994年起 ,将“近自然林业”的经营方式应用于杉木人工林的经营中 .5a的试验结果表明 :与采用常规方法经营杉木相比无论是平均胸高、平均树高、单位面积蓄积量都有大幅度的增长 ,且立地条件越差增长的幅度越大 .用近自然林业经营法经营杉木人工幼林 ,土壤肥力也得到了维护和提高 ,表现在土壤生物活性加强 ,土壤养分增加 ,交换性能改善 ,加速了养分的循环和累积 .表 5参
This paper deals with the application of “nature approximating forestry” method in young Chinese fir plantation from 1994 to 1999. The results showed that average breast height diameter, average tree height and stand volume were promoted by the “nature approximating forestry” management method in the plantation compared with conventional management method. The increments under worse site condition were greater than those under better site condition. The soil fertility was also improved in the experiment plot by using this method. Tab 5, Ref 7
