| 摘 要： | 通过对比研究了山西吴起县植被恢复区不同植被类型的林草地和农田的土壤物理性质,包括土壤容重、土壤孔隙度、土壤水稳性团粒结构。结果表明:不同植被类型的土壤容重为1.17~1.21 g/cm3,差异较小,但均比农田(1.31 g/cm3)低约11%,不同植被类型地各层土壤不同粒径的土壤团粒结构百分含量高于相应的天然草地和农田。实施植被修复后,与农田相比,林地土壤物理性质得到明显改善,混交林的土壤物理性质好于纯林林,天然草地和农田较差,天然草地略好于农田。

| Abstract: | This paper contrasted and researched the soil quality of different vegetation zone with plant restoration and farmland,including soil bulk density,soil porosity,and soil water stable aggregate structure in Wuqi county of Shanxi province.The results showed that the soil bulk density in different vegetation zone varied from 1.17 to 1.21 g/cm3,there is no significant difference.All of which was 11% lower than that in farmland.The percent content of soil aggregate structure in different particle size of differe... |
