摘要/Abstract

摘要： 选取海南5个牧草地样地,以样地附近立地条件一致的林地为对照,研究海南热带砖红壤林地改种牧草后土壤物理性状变化。结果表明:林地改种牧草后土壤平均容重降低3.91%,从1.33 g·cm^-3下降到1.28 g·cm^-3;砂粒含量减少15.89%,粘粒和粉粒含量分别增加17.08%和18.86%;微团聚体(53~250μm)和粉粒与粘粒大小的团聚体(<53μm)含量分别减少57.78%和13.29%,大团聚体(>250μm)含量增加26.28%;同时,土壤渗透性增加77.08%,10℃时渗透系数K10从平均0.96上升到1.70。尽管未能达到显著水平,但林地改种牧草后各种土壤物理性状均有一定改善。

Abstract: Physical properties of 5 grassland plots and their corresponding nearby woodland controls were investigated to study the effect of replanting grass in woodland on latosols in Hainan.Mean soil bulk density decreased 3.91%,from 1.33 g·cm^-3 to 1.28 g·cm^-3 after replanting grass in woodlands.Meanwhile,sand contents decreased 15.89% in grasslands.Clay and silt contents increased 17.08% and 18.86% in grassland,respectively.Soil macro-aggregate(>250 μm) increased 6.28%,whereas soil micro-aggregate(53～250 μm) and aggregates of sand and silt(<53 μm) decreased 57.78% and 13.29%,respectively.Soil permeability increased 77.08%.Mean water permeability coefficient(K10) rose from 0.96 to 1.7 at 10℃.This study indicates that replanting grass in woodlands improved all soil physical properties.

Key words: Land use change from forest to grassland, Soil physical quality property, Latosol, Hainan
