Abstract
Research about economic and ecological evaluation of logging are important. The aim of present study was assessment of production, cost and damage to soil during semi-mechanized skidding and traditional transportation in Siahkal forests of Guilan. To this, after determining two skidding system and determine work elements, number of 110 skidding turns (70 related to semi-mechanized and 40 related to traditional logging) were studied, also soil sampling was done by systematic-random sampling. Resulted showed that the hourly production with and without delay in semi-mechanized skidding were 21.64 and 28.20m3, respectively. Also, resulted showed that the hourly production with and without delay in traditional transportation were 0.31 and 0.33m3, respectively. On the other hand, resulted showed that the unit cost with and without delay in semi-mechanized skidding were 941695 and 856087 Rial per m3, respectively. Also, resulted showed that the unit cost with and without delay in traditional transportation were 1570172 and 1442825 Rial per m3, respectively. Results of soil compaction and soil humidity in two studied skidding system proved that these indicators in trational method is more than semi-mechanized skidding in 0-10cm soil depth. We concluded that using semi-mechanized skidding is more ratinal that traditional transportation.
