1. A mobile tower yarder, RME200T, RME300TC operated by running skyline system was set on different sits of experimental area in the Funyu training forest. On each setting the geometric variables and haul line pulling out time by chorker setters have been measured. The study showed that choker setters could reduce the force exerted by about 20 to 50% when using the carriage equipped with self line extraction mechanism.2. Method for estimating the productivity of a logging system using data-mining program C4.5 was discussed its possibilities and limitations in o the detailed planning of a logging operation in the Funyu training forest. The results obtained clarified that the highest productivity of cable logging was found in yarding with a clear-cut operation or a thinning operation with 2 operators over a 30% thinning rate and under a 78m yarding distance.3. Cable layout method for mobile tower yarder was studied in a clear-cut logging operation. A time-study analysis of mobile tower yarder was used to estimate the machine productivity and operating cost. Analysis indicates that optimizing method using neural network model can be used to improve productivity of tower yarder system. Further result suggest that system productivity of clear cut area is highest when operation site is constructed in small blocks, average 100 to 150m main line cable distance.4. Optimizing method for forest road density using machine power was made up and studied. In this process, result of a time-study analysis of tower yarder, cable yarder and forwarder were used to estimate machine productivity indices and construction cost of forest road. Analysis indicates that optimizing method using machine power can be effectively used to improve the forest road density. Further result suggest that forest road density is highest when using small size yarding machine, and it rapidly decrease after 20 to 100PS.

1、在风雨训练林实验区不同地点设置一台运行skyline系统运行的移动塔式堆场机RME200T、RME300TC。在每一次设置中，都测量了扼流器设置者的几何变量和牵引线拉出时间。研究表明，当使用配备有自线抽出机构的托架时，扼流器设置器可以减少约20%至50%所施加的力。2．讨论了使用数据挖掘程序 C4.5 估算伐木系统生产力的方法在 Funyu 训练林伐木作业详细规划中的可能性和局限性。结果表明，电缆测井生产率最高的是采用清伐作业或由2名操作人员进行间伐作业的码放，间伐率超过30%，码放距离在78m以下。 3．在清晰的测井作业中，研究了移动式塔式堆场机的电缆敷设方法。使用移动塔式堆场机的时间研究分析来估计机器生产率和运营成本。分析表明，采用神经网络模型的优化方法可以提高塔式堆场系统的生产率。进一步的结果表明，当作业场地建在小块内，平均干线电缆距离为100至150m时，净空区的系统生产率最高。4．提出并研究了利用机械功率优化森林道路密度的方法。在此过程中，利用塔式堆场机、电缆堆场机和集运机的时间研究分析结果来估算机器生产率指标和林道建设成本。分析表明，采用机械功率优化方法可以有效提高林道密度。进一步的结果表明，使用小型堆场机时林道密度最高，在20～100PS后迅速下降。
