Abstract:: [Objective] In purpose of providing a scientific basis for vegetation construction and soil nutrient sequestration in riparian zones in plain sandy area, this study investigated the effects of different vegetation types on soil N content and enzyme activity in riparian zones of Fuxin River in Feng County, Jiangsu Province. [Methods] Three 15-year-old riparian vegetation types, including pure poplar plantation, pure willow plantation and poplar-willow plantation, together with control(CK)were selected, and the nitrogen content and enzyme activity were measured at five soil depths(0—20 cm, 20—40 cm, 40—60 cm, 60—80 cm, and 80—100 cm). [Results](1)In all vegetation types, the total nitrogen contents, ammonia nitrogen contents, nitrate nitrogen contents, microbial biomass nitrogen contents of the four soil layers(except for soil layers≥60 cm)were higher than those of CK. Soil total N contents varied from 0.20 to 0.75 g/kg(with a ranking of pure poplar plantation>pure willow plantation>poplar-willow plantation), and generally decreased with increasing soil layer depth, with a significant higher content in 0—20 cm. Soil ammonium and nitrate nitrogen contents were highest in pure poplar plantation, in which they declined along soil depth. Soil microbial biomass nitrogen content was the highest in poplar-willow plantation and lowest in pure poplar plantation.(2)Soil urease, nitrate reductase and nitrite reductase activities varied between 0.30～4.35, 0.05～0.21 and 0.46～0.59 mg/(g·d), respectively. The activities of the three enzymes were the highest in pure poplar plantation and differed significantly among vegetation types and soil layers(p<0.05).(3)Redundancy analysis showed that soil organic carbon content, fine root biomass and litter biomass were the dominant factors influencing soil N content and enzyme activity. [Conclusion] The highest soil nitrogen content and enzymatic activity were found in the pure poplar plantation, due to the high soil organic carbon content, fine root biomass and litter biomass. This implies that the selection of suitable vegetation types in the riparian zone of the plain sandy area can improve the soil nitrogen sequestration capacity, which in turn may reduce the loss of soil nutrients.
