| 摘 要： | 对山东省临朐县辛庄水土保持试验站径流小区4种植物（花生、沙打旺、草木樨和自然草地）的3个坡度（5°，15°和25°）连续5 a的汛期径流、侵蚀观测数据，分析不同坡度条件下径流小区汛期径流量和侵蚀量。试验结果表明:相同坡度径流小区4种植被的水土流失量随降雨量的增大而加剧；相同降雨条件和相同坡度径流小区4种植被的水土流失量从大到小顺序均为:花生>自然草地>沙打旺>草木樨；4种植被的水土流失量随坡度的升高而增加，5°小区<15°小区<25°小区。

| Abstract: | This article studied the change of soil and water erosion with rising of the slope under the four kinds of vegetation of Arachis hypogaea L., Astragal us adsurgens Pall., Melilotus suaveolens and grassland in Linqu Xinzhuang valley of Shandong.At plot scale, an experiment investigated upon soil erosion of the four kinds of vegetation on gentle-hill slope (5°, 15°, 25°) was performed over a period of 1986-1990.The results showed that the magnitude of soil erosion of the four kinds of vegetation increases with rising of the precipitation amount in the same slope, the sequences of the magnitude of soil erosion of the four kinds of vegetation were:Arachis hypogaea L.>grassland>Astragalus adsurgens Pall.>Melilotus suaveolens in the same slope and precipitation amount.The magnitude of soil erosion of the four kinds of vegetation increases with rising of the slope (5°<15°<25°). |
