| 摘 要： | 利用自行设计的实验装置和5种土著草皮构建草皮缓冲带，模拟上海地区农业面源污染和降雨特征，进行缓冲带污染物净化效果和草皮生物量监测实验研究结果表明，草皮缓冲带对径流污染物质的净化效果明显高于空白对照，百慕大实验带SS平均截留率最高，达到74％；白花三叶草TN、TP去除率最高，分别为28％和25％；黑麦草受高温的影响，污染物净化效果最差．5种草皮中．百慕大和白花三叶草生物量最大，栽种当年9月份，两者地上部分的生物量鲜重分别为6．14kg／m^2和6．49kg／m^2：百慕大生长速度最快，9月份生物量几乎达到5月份的6倍；草皮生物量的增加明显提高了缓冲带对径流污染物的去除效果，生物量与径流SS去除率呈显著线性相关关系．

| Abstract: | To examine the pollutant removal efficiency of different sward buffers to runoff and the correlation with biomass, 5 native grasses were selected to construct buffer strips and conduct an experiment under the simulation of agricultural non-point pollution and rainfall characteristics in Shanghai. The results showed: 1) the clarification efficiency to runoff of sward buffers was significantly better than the blank control, the SS average retention rate of Cynodon dactylon buffer strip was the highest, up to ... |
