摘要
在福建省长汀河田强度侵蚀山地,采用径流小区观测法,探讨了3种不同治理措施对坡面径流及土壤侵蚀的影响,结果表明：不同治理措施区的坡面径流系数和土壤侵蚀模数均大幅下降,与未治理的对照区相比,治理措施区径流系数减幅达38.0%~45.9%,土壤侵蚀模数下降幅度达91.6%~95.1%,不同处理保水保土效益的总体趋势是：草灌乔措施〉补植乔灌〉老头松改造〉对照,采用草灌乔混交措施的蓄水保土效果最好。
By using the runoff plot observation method,it was analyzed the impacts of three different management measures on the slop runoff and soil erosion.The result shows that both the slope runoff coefficient and soil erosion modulus in different management plots decreased greatly.Compared with that of control plot,the runoff coefficient in the management plot is decreased by 38.0% to 45.9%,and the soil erosion modulus is decreased by 91.6% to 95.1%.The general trend of the soil conservation benefits by different management measures appears at grass ＋ shrub ＋ arbor planting measures arbor ＋ shrub repair planting measures rehabilitation of Degraded Inferior Masson Pine control plot.The plot by using the mixing planting measure of grass ＋ shrub ＋ arbor has the best soil conservation benefit.
