| 摘 要： | 采用坡面径流场和三角形-梯形复合测流堰方法,观测了芦花冲小流域多功能防护林林地的径流、泥沙及土壤物理性质变化。结果表明多功能防护林体系的水土保持效果明显,不同造林模式林地同对照比较,坡面径流量减少17.75%~77.41%,泥沙流失量减少55.24%~89.83%,土壤容重减少3.00%~30.30%,土壤总孔隙度增加12.67%~75.55%。应用世行多功能防护林造林模式营造林3~4a后,林地的水土流失可以得到基本控制。 |

| Abstract: | Based on the methods of runoff plot on sloping land and triangle-trapezoid multi-measuring weirs, the runoff, sediment and change of soil physical character were observed. Results indicated that the effect of soil and water conservation with multifunctional protection forest were tangible,compared with the cheek, the surface runoff of different afforestation models decreased from 17.75 % to 77.41%, the sediment yield decreased from 55.24% to 89.83% ,soil bulk density reduced from 3.00% to 30. 30%, and the total soil porosity increased from 12.67% to 75.55%. After 3-4 years of multifunctional afforestation models were applied through the World Bank project,the soil and water loss of forest land could be basically controlled. |
