| 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pH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。

| Abstract: | This study analyzes the environment impact by soil erosion from tea garden through watershed export. The results indicated pH was decreased, and nutrient elements and suspended sediment were lost by rainfall. 71.2% of water pH 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. |
