摘要
通过对各项与林道网养护年限有关费用的系统分析，建立了合理养护年限的决策模型． 模型的应用分析表明， 林道网的合理养护年限与林道修建费和经营的林种有关， 但与林道网密度无关；
The paper developed the decision model for the optimum years of maintaining forest road network based on the analysis of all costs relative to the years.The model was applied Results show that there are significant relationships \{among\} the optimum years,the building cost of forest roads and the kind of forest,but there is no significant relationship \{between\} it and forest road density;it is no less than 4 years.
