| 摘 要： | 通过在北票市、凌源市设立对比试验,对困难立地造林后的水土保持效果进行了分析比较。结果表明,造林后林地的地表径流和土壤侵蚀量与对照相比,没有增加;降雨量相同时,地表径流和土壤侵蚀量随着造林时间增加而降低。

| Abstract: | Based on the comparative experiment in Beipiao City and Lingyuan City,the effect of soil and water conservation after afforestation on difficult site was analyzed and compared.The results showed that the surface runoff and soil erosion of forested land did not increase after afforestation compared with the control,and the amount of surface runoff and soil erosion decreased with the increase of afforestation time under the same precipitation. |
