| 摘 要： | 基于运载量对集材道表层土壤物理性质影响的研究,将运载量限定为1.0m^3/趟,研究采伐作业1 a后集材道表层土壤主要化学性质的变化情况。研究结果表明：1 a后,集材道表层土壤主要化学性质指标均有不同程度的变化（降低）,其中以速效N、速效K含量的变化程度最高,均表现出接近50%的损失率,土壤pH值的变化程度最低,其他化学性质变化幅度为10%-20%。速效养分的大量损失,不利于森林环境的恢复。

| Abstract: | Based on the research of the carrying amount influence on the surface soil's physical properties on skidding road,this test limits the carrying amount for 1.0 cubic meter per time,and researches the main chemical properties changing situation of surface soil on the skidding road one year after felling work.The results show,one year later,the skidding road surface soil's entire main chemical properties indexes have different degree changed(decreased).Among which,Rapidly Available N and Rapidly Available K sh... |
