摘　　要：发展柞蚕生产是否会对柞树的生长以及山区的生态环境产生不良影响,一直是一个存在争议的问题。根据植物的生长冗余理论与补偿机制并结合已有的柞树去叶试验和柞蚕放养试验结果分析表明:柞树部分去叶后有利于光合同化产物向枝条和剩余叶片中的分配,补偿因去叶带来的地上与地下部分的生长不平衡,直到二者恢复正常比例;柞树的生长冗余现象和补偿作用主要体现在茎、叶等主要部位与器官,以及柞树夏梢的二次生长方面。据此认为,采用科学方法放养柞蚕和管理柞树能够使柞树的生长特性与放养柞蚕有机结合,使柞树生长保持一种相对平衡的状态,实现柞林资源的可持续利用。The problem of whether the development of tussah production has a harmful effect on oak tree growth and on ecological environment of mountainous area has long been in dispute. By using the redundancy theory and compensation mechanism of plant growth and combining with the pre-existing experiments of simulated defoliation and tussah silkworm rearing, we drew a conclusion that the partial defoliation of oak was beneficial for the distribution of photosynthetic prod- uct in branches and remaining leaves so as to compensate imbalance of the ground and underground until both of them returned to normal. Growth redundancy phenomenon and compensation effect of oak are mainly manifested in the main parts and organs such as stem and leaf, and in secondary growth of summer shoots. It is thus suggested that, the or- ganic combination of oak growth characteristics and tussah silkworm rearing could be realized by using scientific method to rear tussah silkworm and manage oak. Therefore, the growth of oak will be able to maintain a state of relative balance, making it realizable to have sustainable utilization of oak forest resource.
