| 摘 要： | 以黄土高原沟壑区纸坊沟流域为例,选择农田(大豆)为对照,分析不同林龄(12、25、30 a)刺槐、油松、苹果、柠条、沙打旺等不同人工植被恢复模式下土壤理化性质、有机质等的特征。结果表明,黄土高原沟壑区纸坊沟流域不同植被恢复模式下,各层土壤有机质、速效氮、速效磷、速效钾含量均随深度增加而递减,且有一定的表聚性,其中刺槐表聚性表现最明显。几种不同植被恢复模式均能够显著提高土壤有机质、速效氮、速效磷、速效钾含量,改善土壤肥力,其中尤以刺槐的效应最为明显。 |
| 关 键 词： | 黄土高原 纸坊沟流域 植被恢复模式 土壤肥力 |

| Abstract: | Soil physiochemical properties in the soil under Robinia pseudoacacia,Pinus tabulaeformis,Malus pumila,Caragana korshinskii and Astragalus adsurgens were studied,compared with the soya land by taking Zhifanggou watershed in the gully region of Loess region as an example.The results showed as the follows: soil organic matter,available nitrogen,available phosphorus and available potassium content under the several vegetation restoration models was decreased with soil deep increased,which was more obvious for ... |
