采用重庆市常见植物进行现场、盆栽和PO_4~(3-)吸附等温试验.探讨植物配置与面源氮磷削减的关系.结果表明,河岸生态建设中不同植物配置的面源氮磷去除效果不同,对泥沙结合态氮磷的去除."蝴+吉+樟"混栽的去除效果较显著;植物混栽中,乔木覆盖率越高,对泥沙结合态氮磷去除效果越差.对水溶态营养盐的去除.各盆栽对NO_4~(3-)去除效果不显著.有株盆栽能有效地减少NO_4~(3-)流失;对PO_4~(3-)的去除,各盆栽都具有显著效果;土壤含水率与PO_4~(3-)去除率反相关;磷的吸附能力,壤土高于沙土;植物对土壤磷吸附影响,吉祥草最显著,蝴蝶花次之.桃花溪河岸生态建设中应采用"蝴+吉+栀+樟"配置,其布局为蝴蝶花、吉祥草分层种植,蝴蝶花位于上端,香樟、海栀子、吉祥草混种.

In order to study the relationship between the plant disposition and the reduction of nitrogen and phosphorus in the riparian ecological construction of Taohua river in Chongqing, the field test, pot experiment and phosphorus adsorption isotherm experiment were carried out. The results show that the different plant dispositions have different effects on the reduction of nitrogen and phosphorus; the combination of Iris japonisa, Reineckia carnea and Cinnamomum camphora enjoys higher efficiency for removing particle-bound nitrogen and phosphorus; the higher the tree coverage, the lower the efficiency will be; the pot has no significant effect on the removal of NO_3~- (nitrate), but has effect on the removal of PO_4~(3-) (phosphate), and the pot with plants can prevent the loss of NO_3~-; the soil water content and the PO_4~(3-) removal efficiency are anti-related; the loam phosphorus adsorption capacity is higher than that of the sand, with that of the Reineckia carnea being the highest, followed by that of Iris japonisa; the combination of Iris japonisa, Reineckia carnea, Gardenia Ellis var fortunianct and Cinnamomum camphora should be adopted in Taohua river, with the Iris japonisa being put above the Reineckia carnea, and Gardenia Ellis var fortuniana, Cinnamomum camphora being mixed planted with Reineckia carnea.
