摘 要：
以中山杉林、杨树林、中山杉—杨树林3种太湖人工林缓冲带为研究对象,分析不同缓冲带宽度对富营养物质磷素的截留效果差异,为确定缓冲带适宜宽度提供科学依据。结果表明:3种类型人工林缓冲带径流水中的磷酸根质量浓度没有特定的空间趋势,总磷、可溶性总磷随宽度增加质量浓度减少,研究区人工林缓冲带对径流水中总磷的最大去除率可达78.2%。土壤总磷质量分数随宽度的变化呈极显著正相关(p<0.01)。回归分析得出径流水中的总磷去除率达80%时,最佳人工林缓冲带为43.64 m宽的杨树林带。

摘 要：
An experiment was conducted to study the effects of phosphorus removal by three types of Taihu Lake riparian plantation buffer strips,including Taxodium ‘zhongshansha'forest,Poplar forest and Taxodium ‘zhongshansha'-Poplar mixed forest in terms of width. The PO43-contents of surface runoff did not follow any specific spatial trend in the three kind of riparian plantation buffer strips. The total phosphorus and total dissolved phosphorus contents of surface runoff showed decline trend with the increase of width,and the total phosphorus retention efficiency was as the highest as 78. 2%. Total phosphorus contents of soil were significantly positive correlation with strip width( p<0.05). When the removal rate of total phosphorus was 80%,the Poplar forest with 43.64 m width could be as the priority plantation for buffer strips near Taihu Lake by polynomial regression analysis.
