The results obtained in this research are as follows. 1. We studied profitable forest road density and evaluation method of forest road location for profitable logging in multi-storied forest. And the profitable density for profitable logging system in multi-storied forest is needed over 70 m/ha. 2. We studied profitable logging system in multi-storied forest or national forest and logged in experiment by logging using truck crane at Tokyo University forest in Hokkaido. 3. We logged in experiment with truck-crane in ground lead method, high- lead method and running skyline method. The most profitable method of truck-crane was logging in running skyline method. Its working efficiency amounted to 40 m3/day. 4.The method of forest road net constructions was studied and established. And using this method the forest road net was constructed at Tokyo University Forest in Hokkaidou in these years. 5. We also studied the logging method of the truck-crane using with computer simulation. We could find adequate logging distance for truck- crane in multi-storied forest.

研究结果如下：1.研究了复层林分经济性采伐的经济性林道密度和林道位置的评价方法。在复层林中，经济采伐系统的经济密度应大于70 m/ha。2.研究了在多层林或国有林中的有效采伐系统，并在北海道的东京大学森林中使用汽车起重机进行了采伐试验。3.采用汽车起重机进行了地面超前法、高超前法和运行天际线法的试验。汽车起重机最经济的方法是采用运行天际线法。其工作效率达到40立方米/天。4.研究并建立了林道网建设方法。近年来，北海道东京大学森林利用该方法进行了林道网的建设。5.并对汽车起重机的测井方法进行了计算机仿真研究。汽车起重机在复层林中可以找到合适的采伐距离。多层林;采伐作业系统;线路疏伐;汽车起重机;高密度林道网;地面引导法;运行天际线法。
