摘要

对红松、水曲柳纯林与混交林的土壤水分物理性质进行了观测和对比分析。结果表明，红松与水曲柳混交后，无论是从各土层还是整个土层的平均值看，混交林中土壤容重较红松纯林降低。土壤总孔隙度、毛管孔隙度、非毛管孔隙度、土壤饱和持水量、毛管持水量、田间持水量、凋萎系数、有效含水量、贮水能力、渗透系数K10等均较红松纯林明显增加，就整个土层的平均值而言，分别增加19.17%，21.50%，12.17%，32.68%，24.29%，42.22%，19.72%，27.71%，12.17%和39.44%。研究结果表明，红松与水曲柳混交后土壤的孔隙状况得到了改善，混交林土壤保持水土，涵养水源的功能较红松纯林明显提高。

Abstract

Soil moisture properties under the pure and mixed plantations of Pinus koraiensis and Frax inus mandshurica were measured and analyzed. The result showed that for each soil layer or the whole soil profile

the soil bulk density under the mixed plantation was lower than that of the pure plantation of Pinus koraiensis. But the total porosity

capillary porosity

non-capillary porosity

soil maximum moisture capacity

capillary capacity

field capacity

wilting point

available water capacity

water storage capacity

permeating coefficient under the mixed plantation were all significantly greater than those of the pure plantation of Pinus koraiensis

with the relative increases averaged over the entire profiles being 19.17%

21.50%

12.17%

32.68%

24.29%

42.22%

19.72%

27.71%

12.17% and 39.44%

respectively.The results showed that the soil pore condition in the mixed plantation

compared with the pure plantation

was improved

resulting in better functionality of water and soil conservation.
