摘要
本文根据低强度择伐在北方林区广泛应用的实际需要，分析了低强度择伐区林道网的特点和与林道网相关的费用因素，运用林道网基本理论，以林道网相关的总费用最小为优化目标探讨了低强度择伐伐区林道网合理密度的问题。
According to the actuaI need of selective cutting in north forest area,the pa-per analyses the specialities and costs of forest road network in selective cutting area,appliesthe basic theorv of forest road network and optimal oUective of the smallest total costs to de-termine the reasionable density of forest road network for selective cutting system.
