| 摘 要： | 选择黄土高原地区典型人工林为研究对象,以土壤有机质和阳离子交换量(CEC)等理化特性为评价指标,研究了不同人工林对林地土壤肥力的影响。结果表明,成龄油松和刺槐林对土壤的培肥效应超过其幼龄林;成龄油松林和刺槐林土壤几乎无石灰反应;在树龄相同的条件下刺槐林对土壤培肥效应优于油松林。

| Abstract: | With the typical plantations on Loess plateau as the subject,the change of soil fertility was studied in different types of plantations according to soil organic matter,nutrition and CEC. It can be observed that:the soil fertility can be improved significantly by plantation of grown-up Pinus tabulae formis and Robinia pseudoacacia;The soil under grown-up Pinus tabulae formis and Robinia pseudoacacia scarcely had CaCO3-Action. Robinia pseudoacacia was better than Pinus tabulae formis in enhancing the soil fertility. |

| Keywords: | age of plantation Pinus tabulae formis Robinia pseudoacacia soil improvement soil fertility |
