摘要/Abstract

摘要： 集材道土壤受拖拉机反复走行作用产生地表轧乱和土壤压实现象,造成水土流失和腐殖质丧失,这对更新苗木的生长产生了不良影响.本文通过实地调查测定,应用灰色系统理论,研究了拖拉机集材时集材道上土壤硬度、孔隙度的变化及对苗木生长的影响。在履带式拖拉机集材道上,土壤的硬度、孔隙度都比轮式拖拉机集材道上的大。与土壤硬度相比,孔隙度对苗木生长的影响更大些。从而得出了就苗木高生长而言,履带式拖拉机比轮式拖拉机的损害要小。

Abstract: Continuously moving skidders,mainly J-50 tracked skidder and J-80wheeled,are widely used in extracting operations in the forests of northeastern China and result in soil erosion and humus loss which seriously affect stand regeneration and growth of remaining crops.Using Grey Theory an investigation was undertaken to analyze soil compaction and seedling growth in the stands under such a harvesting system.It was found that extracting operation caused less damage to soil structure and less effects on the height growth of seedlings by the use of tracked skidders than wheeled ones.

Key words: Extraction, Skidders, Soil structure, Growth of remaining crops
