摘　　要：本文采用系统工程分析方法对大兴安岭林区低效林补植改造工程的生态效应进行了分析,从清林作业、整地作业和补植作业3个方面着手,提出了3个作业过程的输入、转化以及输出技术要求,并依次分析了三个作业过程对作业区生态效应的影响,体现了补植改造工程的系统性和完整性,为保持和提高大兴安岭林区森林生态系统的整体功能与效益提供理论支撑。The system engineering analysis method was used to analyze the ecological effect of low function forest replantation in Daxing＇anling forest region. Based on the three aspects including forest liquidation,soil preparation,and replantation,the input,conversion,and output technical requirements of the engineering system were put forward,respectively,and the influence of ecological effect in operation area was explained. The engineering system could indicate the systematicness and completeness of the low function forest replantation,which could provide theoretical support for maintaining and improving the whole function and efficiency of Daxing＇anling forest ecological system.
