| 摘 要： | 以成都市退耕还巨桉和麻竹林地为研究对象,从土壤容重、孔隙度、持水能力等方面比较研究了这两种退耕地土壤水分物理性质的改善效应。结果表明：用巨桉和麻竹作退耕还林树种明显降低了退耕地土壤容重,增加了退耕地土壤孔隙度、饱和持水量、毛管持水量和非毛管持水量,巨桉和麻竹之间对土壤水分物理性质的改良效应差异不显著。因此,就改善土壤水分物理性质的效果而言,巨桉和麻竹均是较好的退耕还林树（竹）种,明显改善了退耕地的渗透性和透气性,提高了土壤保持水分与涵养水源的能力。 |
| 关 键 词： | 退耕还林 巨桉 麻竹 容重 孔隙度 持水能力 |

| Abstract: | The physical properties of soil moisture,after converting cropland to Eucalyptus grandis and Dendrocalamus latiflorus forests in Chengdu,were comparatively analyzed by using the soil bulk density,soil porosity and soil water-holding capacity.The result indicated that the soil bulk density significantly decreased,and the soil capillary porosity and non-capillary porosity increased after converting cropland to Eucalyptus grandis and Dendrocalamus latiflorus forests.So far as the improvement effect of the phys... |
| Keywords: | Converting cropland to forest Eucalyptus grandis Dendrocalamus latiflorus Soil bulk density soil porosity Soil water-holding capacity |
