中文摘要	应用先进的UGT水蚀测量仪,研究黄土高原祖厉河流域雨强和植被覆盖度对典型坡面产流产沙的影响。结果表明:黄土高原半干旱区间隔为15min的产流量、径流含沙量和产沙量与15min雨强具有相同的增减趋势,呈三次曲线关系y=b_0+b_1x+b_2x~2+b_3x~3。7种雨强条件下,人类扰动撂荒地的产流量、径流含沙量和产沙量均明显大于植被自然恢复的撂荒地,覆盖度20%的撂荒地是覆盖度35%撂荒地的平均径流系数的2.35倍,径流含沙量的4.48倍,产沙量的14.06倍。相对于受到扰动的撂荒地,植被自然恢复的撂荒地水土保持效益显著。
英文摘要	Based on advanced UGT erosion meter,the impacts of rainfall intensity and grass coverage on runoff and sediment yield on typical sloping land in Zuli river basin of the Loess Plateau were investigated.The results show that there are similar changing trends(y=b_0+b_1x+b_2x~2+b_3x~3) between 15min rainfall intensity and runoff,sediment concentration,and sediment yield respectively in semi-arid region of the Loess Plateau.Under the same rainfall intensity of 15min,the runoff,sediment concentration and sediment yield of abandoned land with human disturbance are significantly larger than that of abandoned land with natural recovery.The runoff,sediment concentration anb sediment yield of the land with grass coverage(20%) are 2.35,4.48,14.06 times of the corresponding parameters for the land with grass coverage(35%).Compared with the abandoned land with human distribution,the land with natural recovery shows much better capacity for soil and water conservation.
