| 摘 要： | 选择上海地区常见的5种草皮植被,利用自行设计的试验装置构建草皮缓冲带,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试验研究。结果表明,草皮的存在明显提高缓冲带对污染物的净化效果,并且能增强缓冲带土壤的渗透能力;百慕大缓冲带对径流SS的截留能力最强,平均去除率达到71.86%;草皮缓冲带对渗流水营养物质的净化效果明显高于径流,渗流水TN、TP平均去除率以白花三叶草最高,分别为58.27%和60.49%;综合考虑降雨特征和污染物净化效果等因素,百慕大、白花三叶草和高羊茅等3种草皮,可以作为上海地区缓冲带草皮植被的优先选择种类。

| Abstract: | Five local grasses in Shanghai were selected and the designed test trays were adopted to construct buffer strips for simulation of agriculture non-point and rainfall characteristics in Shanghai. Results showed that grass can enhance the pollutant purifying effect and penetrating power of buffer strips,with SS removal efficiency as the highest as 71.86% for buffer strip with planted Cynodon dactylon. Nutrition purifying effect of seepage was obviously higher than runoff for buffer strip,with TN and TP remova... |
