摘　　要：为了探究南方红壤区茶园不同治理措施对水土流失的影响,基于安溪县官桥坡面径流观测场连续10年的资料,研究工程措施和工程+植物措施的径流产沙特征。结果表明:三个措施区的月径流深最大的月份出现在6~9月,三种措施小区年均径流深的大小排序为无处理(454.9mm) >梯田清耕(108.0mm) >梯田种植百喜草(93.0mm),年均土壤流失量的排序为无处理(218.1t/hm^(2))>梯田清耕(10.4t/hm^(2))>梯 田种植百喜草(1.4t/hm^(2)),梯田种植百喜草控制水土流的效果优于无处理和梯田清耕;相关分析结果表明,不同治理措施小区的径流深与雨量、I_(30)和降雨侵蚀力呈极显著正相关,梯田种植百喜草的土壤流失量与雨量、平均雨强、I_(30)、降雨侵蚀力相关性均没有达到显著水平。In order to explore the impact of different control measures on soil erosion in tea gardens in the red soil region of South China,it was studied the runoff and sediment characteristics of engineering measures and engineering+plant measures based on continuous data from the Guanqiao slope runoff observation field in Anxi County for 10 years.The results showed that the months with the highest monthly runoff depth in the three measure areas occurred from June to September.The order of the average annual runoff depth in the three measure areas was no treatment(454.9mm)>terrace clearing(108.0mm)>terrace planting of Paspalum notatum Flugge(93.0mm).The order of the average annual soil loss was no treatment(218.1t/hm^(2))>terrace clearing(10.4t/hm^(2))>terrace planting of Paspalum notatum Flugge(1.4t/hm^(2)).The effect of controlling soil and water flow by terrace planting of Paspalum notatum Flugge was better than that of no treatment and terrace clearing.The correlation analysis results show that there is a highly significant positive correlation between runoff depth and rainfall,I,and rainfall erosivity in I_(30) different control measures areas.However,the correlation between soil erosion and rainfall,average rainfall intensity,I_(30),and rainfall erosivity in terrace planted with Paspalum notatum Flugge did not reach a significant level.
