摘要
安远县国营林场根据生态学原理,对阔叶次生林进行改造,把天然更新和人工改造更新有机地结合起来。通过改造可很快的形成多树种的混交林,林木材积生长提高115％～219％,土壤物理性比杉木纯林好,土壤贮水量比杉木纯林提高57％～92％,有良好的生态经济效益。实践证明,次生林改造是次生林经营的重要措施,是加速培育森林资源的好途径。
According to the principle of ccology,the broad-leaved second growth stand of stoie forcst farm of Anyuan County was improved.By combining natural afforestation with ari ficial improving regeneration, mixed forests of multiple species soon took shape and tie volumes of trees increased by 115～219 percent. Thc physical property of the soil in ths stand was better than that of pure forest of Chinese-fir. The water retaining capicity of sol increased by 57～92 percent. Showing better ecological and economical benefit. This fac shows: the improvement of second growth stand is a major method in its managment anc an effective way to speed up the growth of forest resource.
