| 摘 要： | 对枫杨1年生幼苗9—11月在4组总氮(TN,质量浓度分别为 20、300、400和800 mg／L)和总磷(TP,质量浓度分别为04、80、150和250 mg／L)的模拟富营养化水中的生长状况、形态变化及其对各浓度富营养化水中TN、TP的去除效果进行了研究。结果表明:枫杨对富营养化水适应性较强,在不同浓度的富营养化水中形态生长状况良好,株高、基径、叶片数均有不同程度的增长;对不同浓度富营养化水中的TN和TP净化效果良好,平均去除率分别为831 ％与2379 ％,其中对低浓度富营养化水中的TN、TP去除效果最佳,平均去除率分别高达1706 ％和 4086％。由此可知，枫杨是值得大力推广的净化富营养化水中TN与TP的湿生乡土树种。 |

| Abstract: | This paper investigated the morphologic changes and the uptake effect on TN and TP in eutrophic water by using one-year seedlings of Pterocarya stenoptera,which were planted in 4 treatments of simulated eutrophic water with various concentration of TN as 2.0,30.0,40.0,80.0 mg/L and TP as 0.4,8.0,15.0,25.0 mg/L respectively from September to November,2009.Results showed that P.stenoptera had rather strong adaptability to the eutrophic water,and they grew well in it,with height,stem base diameter,leaves numbe... |
