| 摘 要： | 以卓资县的退耕还林地为研究对象,探讨不同退耕还林地土壤物理性质的变化,初步研究结果表明:退耕还林8 a后,相同立地条件、不同林种间土壤毛管孔隙度和非毛管孔隙度差异极显著,而总孔隙度差异不显著;总体上退耕还林地土壤粘粒含量高于耕地,其中0～20 cm增加不显著,20～40 cm、40～60 cm增加较多;除柠条林地外,其他林地土壤容重0～20 cm土层高于20～40 cm、40～60 cm土层。

| Abstract: | This paper studied the soil of Zhuozi County after cropland conversion to forest,explored the change of the soil physical properties after cropland conversion to forest and the preliminary findings showed that:after 8 years of returning farmland to forests,Capillary porosity and non-capillary porosity of different forest species in the same site condition were significantly different.Total porosities of the soil weren't significant;wherever,wholly the clay content was higher than the cultivated land after r... |
