摘要

在野外调查和室内实验分析的基础上，研究了黄土丘陵区人工油松林生长发育过程中的细根垂直分布特征及其土壤特性。结果表明：(1)小密度林地改善土壤结构能力最好，其次是中、大密度，采伐地最差。(2)小、中、大密度林地0—300 cm土层土壤含水量分别为12.95%，12.87%和12.78%，表现出随林分密度增加而减少的变化趋势，采伐地则为17.10%，说明采伐地土壤水分在一定程度上得到了补偿。(3)油松细根主要分布在0—60 cm土层，占细根总量的90%以上。(4)细根分布与土壤特性关系密切，以40—60 cm土层最为显著。

Abstract

Based on the field observation and indoor determination

an investigation in Loess Hilly Region was made on vertical distribution of fine root characteristics and soil properties with in the recovery of artificial Pinus tabulae formis.The results showed that:(1)The ability to improve soil structure under the low-density pine forest was better than that under mid-density and high-density forest

and the logging area was the worst.(2)In the 0.300cm layer

the soil moisture content declined with the increasing density

and was 12.95%

12.87%

12.78% and 17.10% respect ively for low-density pine

mid-density

high density pine and logging area

indicating that the soil moisture content of logging area was recovered to some extent.(3)Pinus tabulaeformis roots were mainly distributed in 0-60cm soil layer.(4)There were close relationship between root distribution and soil characteristics

especially in the 40-60 cm layer

where the relationship were very significant.
