Abstract

The need to increase forest enterprises productivity has demanded higher levels of mechanization. The objective of this study was to evaluate the suitability of areas in Espírito Santo State to implement mechanized wood harvesting using short log system. To prospect suitable areas for mechanization, algebra map of Eucalyptus edaphoclimatic zoning, land use and occupation, slope, conservation units and their respective buffer zones was performed. Thus, suitability zones were defined based on edaphoclimatic conditions for evaluated species, with temperatures between 19 and 26ºC, water deficit from 30 to 210 mm and annual average rainfall between 900 and 1800 mm defined as suitable. Land use and occupation was classified as fit, fit with type II limitation, fit with type III limitation and unfit. For slope classes, three categories were created: fit (0 - 27º), fit with limitation type I (27.1 - 35º) and unfit (> 35º). Results showed that State has 39.45% of its entire area able to implement mechanized wood harvesting for Eucalyptus and 47.91% is unfit. With results, authors concluded that Northeast micro-region stood out with large areas suitable for Eucalyptus harvest mechanization and employed methodology has potential for use and adaptation in other study areas around world.

机械化木材采伐能力分区

提高森林企业生产力的需要要求更高水平的机械化。本研究的目的是评估圣埃斯皮里托州地区是否适合使用短原木系统进行机械化木材采伐。为了寻找合适的机械化区域，绘制了桉树土壤气候区划、土地利用和占用、坡度、保护单位及其缓冲区的代数图。因此，适宜区是根据评估物种的土壤气候条件确定的，温度在19至26ºC之间，缺水量在30至210毫米之间，年平均降雨量在900至1800毫米之间。土地使用和占用分为适合、适合第二类限制、适合第三类限制和不适合。对于坡度类别，创建了三个类别：适合（0-27º）、具有限制类型I的适合（27.1-35º）和不适合（>35º）。结果表明，该州有39.45%的地区能够实施桉树的机械化采伐，47.91%的地区不适合。研究结果表明，东北微区是适合桉树机械化采伐的大面积区域，该方法具有在世界其他研究领域应用和适应的潜力。
