The realization of ecological skidding of artificial forest is discussed in terms the choice of skidding modes and the determination of harvesting and cultivating mode.

This paper researches two operational modes of trucks in container port and establishes simulation models to compare the two operational modes.

Through analysis and evaluation on four kinds of wood transportation models commonly used in our country s southern artificial forest area,the result shows that under the same operation conditions,the economic benefits,ecologic benefits,social benefits and comprehensive benefits of different operation models of different wood transportation are different.

Analysis on collecting operation mode s influence on forest ecological environment in cutting area;
