摘要：

采用室内模拟降雨装置研究了三峡库区黄色石灰土的养分流失规律。雨强对径流的养分浓度和泥沙的养分浓度无关 ,但可影响其浓度峰值出现时间 ,并与养分流失量呈正相关 ;径流中养分浓度远低于泥沙养分浓度 ,坡面养分流失以泥沙携带为主 ,但由于径流中养分以可溶态速效养分为主 ,径流携带的养分流失不容忽视

摘要：

With simulated rainfall equipment, the pattern of soil nutrient from terra gialla soil was studied. Result showed that the consistency of nutrient in the runoff and sediment was not interrelated with the rainfall intensities. But the time of superlative consistency emerging was effected by rainfall intensities. There was significant positive correlation between the amounts of soil nutrient loss and rainfall intensities. This experiment also found that the consistency of nutrient in the sediment was exceedingly more than the consistency of nutrient in the runoff. But the primary of the nutrient in runoff was readily available nutrient, so the nutrient removed by runoff could not neglect.
