摘要
分析了人工针叶纯林生产力下降的原因。通过对人工针叶纯林与天然的或人工的针阔、阔叶混交林在物种间相互作用、资源利用、营养元素循环规律和生产力方面的比较分析，探讨了优质阔叶材混交林可持续经营的理论基础。认为培育优质阔叶材混交林是实现森林可持续经营的有效途径。
Abstract The reasons causing the productivity descend of pure coniferous plantations are
analyzed. It also explored the theoretic bases of sustainable management of mixed forests, by
comparing mixed forests with pure plantations on interactions between species, resource
utilization, nutrient cycling, and productivity. The result shows that cultivating high quality
hardwood mixed plantations is an effective way to achieve sustainable forest management.
