| 摘要: |
| 为了客观评价人工油松林不同层次水土保持功能，利用定位观测的方法研究了不同处理人工油松林地的水土流失量。结果表明，与原状油松林相比，林地去掉枯枝落叶层、采伐上层林木保存草灌和枯枝落叶层、采伐林木开垦为农地的地表径流量分别增加了3.6，2.7和5.5倍；土壤侵蚀量分别增加了15.4，8.4和949.9倍。降水特征值与径流量之间相关关系不显著。 |

| Study on soil and water loss of different treatments on artificial chinese pine woodlands in Loess Plateau |
|
|
| Abstract: |
| The soil and water loss amount of different treatments on artificial chinese pine woodlands have been studied in the paper using the method of local measurement on purpose to evaluate the soil and water conservation functions of the different layers of artificial chinese pine.The results of the study showed that compared with the original chinese pine,the runoff and soil erosion on woodland without litter,clear land with bush,grass and litter cover and farmland are increased by 3.6,2.7,5.5 times and 15.4,8.4,949.9 times,respectively.Rainfall typical value has no obvious correlation with runoff volume. |
