| 摘 要： | 对辽东地区日本落叶松人工林林地土壤的持水性能进行了实测研究。结果表明:按不同林龄和不同坡向划分的林型,其土壤的物理性质、持水性能及其涵养水源方面都存在着显著差异。7种林型土壤容重排序为:荒地>幼龄林阳坡>幼龄林半阴坡>中龄林阳坡>中龄林阴坡>近熟林阳坡>近熟林阴坡。土壤孔隙度排序则表现为与容重相反。不同林型表层土壤的物理性质与林地凋落物之间存在着显著相关关系。林地土壤在持水性能和涵养水源方面表现为:近熟林阴坡>近熟林阳坡>中龄林阴坡>中龄林阳坡>幼龄林半阴坡>幼龄林阳坡>荒地。与无林荒地相比,可以看出日本落叶松人工林具有明显的涵养水源功能。 |
| 关 键 词： | 林型 土壤容重 土壤孔隙度 土壤持水性能 涵养水源 |

| Abstract: | The soil water-holding capacities and water conservation function of Larix Kaempferi plantation forests in Eastern region of Liaoning province were measured and analyzed.The results showed that there were significant differences exited in soil physical properties,soil water-holding capacities and water conservation function between the forest types had been separated by different age and slope aspect.The volume weight of soil order of the seven forest types was wasteland>sunny slope of the young forest>half... |
| Keywords: | forest types soil volume weight soil porosity water-holding capacities water conservation function |
