中文摘要	采用人工模拟降雨方式,研究了中度石漠化山地N、P、K流失的特征.结果表明,不同降雨强度下,径流中N、P、K流失浓度,K>N>P,且径流中N和K的浓度总体上呈下降趋势,P流失没有明显下降.随着降雨历时,径流中的N、K浓度波动性较小,而P波动性较大.不同雨强,营养元素间关系有正相关,也有负相关.
英文摘要	The loss characteristic of N, P and K nutrient in the hilly area with the moderate rocky desertification level was studied under the condition of artificial simulated rainfall. The result showed that the loss concentration of N, P and K nutrient in surface runoff was K>N>K under different rainfall intensity and the N and K concentration in surface runoff declined overall but P loss was not obvious. There were a little fluctuation in N and K concentration in surface runoff during the observed period but the fluctuation of P content was greater than N and K nutrient. There was a positive or negative correlation between different nutrients under different rainfall intensity.
