【摘要】 随着面源污染的加重及乡村振兴战略的提出,人们更加重视农村的生态环境建设。植物是环境生态效益发挥的主要影响因素,在农村生态环境建设过程中,植物种类应用的选择显得尤为重要。本研究以农村坑塘沟渠常见的3种优势适生植物香蒲（Typha orientalis）、芦苇（Phragmites australis）、水蓼（Polygonum hydropiper）为研究对象,通过3种植物总氮、总磷富集能力的比较研究,为坑塘沟渠绿化植物选择提供参考。试验结果表明:单位土地面积内3种植物富集总磷的能力为香蒲>水蓼>芦苇,富集总磷的量分别为2.90,2.31,0.52 g·m^-2;单位土地面积内3种植物富集总氮的能力为香蒲>水蓼>芦苇,富集总氮的量分别为11.82,8.13,4.17 g·m^-2。在开展农村生态环境建设改造时,可根据该研究结果和坑塘沟渠现状特点,选择合适的植物。若想降低坑塘沟渠土壤总磷和总氮含量,可优先选用香蒲作为主要绿化植物。更多还原

【Abstract】 With the aggravation of non-point source pollution and the proposal of Rural Revitalization Strategy, people pay more attention to the construction of rural ecological environment. Plants are the main influencing factors of environmental and ecological benefits. In the process of rural ecological environment construction, the selection of plant species is particularly important. In this study, three dominant suitable plants, Typha orientalis, Phragmites australis and Polygonum hydropiper, which were common in rural pits, ponds and canals, were taken as the research objects. Through the comparative study of the enrichment capacity of total nitrogen and total phosphorus of the three plants, it provided a reference for the selection of greening plants in pits, ponds and canals. The results showed that the enrichment capacity of total phosphorus of the three plants in unit land area was Typha orientalis >Polygonum hydropiper >Phragmites australis, and the enrichment amounts of total phosphorus were 2.90, 2.31 and 0.52 g·m^-2 respectively. The total nitrogen enrichment capacity of the three plants in unit land area was Typha orientalis>Polygonum hydropiper>Phragmites australis.The total nitrogen enrichment amounts were Typhao rientalis 11.82, 8.13, 4.17 g·m^-2 respectively. When carrying out the construction and transformation of rural ecological environment, appropriate plants can be selected according to the research results and the current characteristics of pits, ponds and ditches. If you want to reduce the content of total phosphorus and total nitrogen in pit, pond and ditch soil,Typha orientalis can be preferred as the main greening plant.更多还原
