摘 要:对黑龙江省畜力集材作业方式的变化发展历程做了简要分析。利用SPSS软件,应用主成分分析法,选取公顷集材量、集材距离、集材成本、单株材积、集材道坡度和公顷蓄积量6个指标,定量计算分析畜力集材发展的驱动源。结果表明,公顷集材量、集材距离、集材成本和单株材积是促进畜力集材作业方式发展的主要因素,对生态环境影响小也是畜力集材发展的重要驱动因素之一。同时,预测指出畜力集材在黑龙江省林业今后几年的集材作业方式中仍占有主导地位。The change and development process of animal logging operations in Heilongjiang Province were briefly analyzed,then six indicators including skidding volume per hectare,skidding distance,skidding cost,single tree volume,gradient of log-skidding trail,and volume per hectare were selected to quantitatively calculate and analyze the driving source of animal-powered logging development using SPSS software and the principal component analysis method.Results showed that skidding volume per hectare,skidding distance,skidding cost,and single tree volume were the major promotion factors on the development of animal logging operation in Heilongjiang Province.In addition,little impact on the ecological environment was also an important driving factor.Meanwhile,it is predicted that the animal-powered logging will still occupy a dominant position among logging methods in the next few years in the forestry of Heilongjiang Province.
