| 摘 要： | 以松华坝上游迤者实验小区为研究对象,在自然降雨条件下,取出7月份的数据对不同土地利用类型磷的浓度进行分析。结果表明,不同土地利用类型对农田污染物输出有较大的影响,总磷流失浓度的规律为土豆和黄豆地〉土豆地〉裸露地〉杂草地〉灌木林,耕地的污染物输出浓度较高。

| Abstract: | Took Yizhe testing plot of the upstream in Songhua Dam as the study object and runoff concentration of P in different land categories in June were analyzed.The results showed that different land use types had a big effect on the farmland pollutants output.The Law of runoff concentration P was land with potato and soya bean>potato land>bare land>grass land>shrub land.General speaking,concentration of the farmland pollutants output is higher. |
