摘　　要：以安溪县感德镇坡耕地茶园为监控对象,小流域集水区为单元,分析茶园水土流失造成的环境问题。结果表明:在降雨的作用下,各养分元素存在不同程度的流失,小流域集水区水质偏酸性,71.2%的水质p H小于6;氨氮含量都在Ⅰ类标准,但总氮含量较高,均超出V类标准限值;悬浮物和降雨量存在正相关,相关系数为0.647,大到暴雨对悬浮物含量具有决定性作用,但悬浮物含量对降雨的响应具有滞后性。This study analyzes the environment impact by soil erosion from tea garden through watershed export.The results indicated p H was decreased,and nutrient elements and suspended sediment were lost by rainfall.71.2% of water p H in this watershed was lower than 6,and the amount of ammonia nitrogen was lower than I standards,but total nitrogen（TN） was higher than the maximum value of V standards.There was a positive correlation between rainfall and suspended solid（r = 0.647）,heavy rainfall had a decisive role in the amount of suspended solid,but it had certain hysteresis.
