Abstract: Nutrient resorption stands as one of the crucial strategies for plant adaptation to environments. Exploring the characteristics of plant nutrient resorption helps to profoundly understand the nutrient cycle of the wetlands in the Yellow River Basin. In June 2022 (during the plant growing season) and at the end of the growing season in November, the green and senescent leaves of plants in three wetland types (riparian wetland, floodplain and depressional wetland) in the middle and lower reaches of the Yellow River were collected, and nitrogen (N), phosphorus (P), and potassium (K) contents in these leaves were measured. The nutrient resorption efficiency was calculated based on the measured nutrient contents in green and senescent leaves. Simultaneously, the surface soil was collected, and main physicochemical indices were determined. The differences in the nutrient resorption efficiency of various plant functional groups of the main wetland types in the middle and lower reaches of the Yellow River and the factors influencing these differences were explored. The results indicated that the nutrient resorption efficiency of the plant community in the middle and lower reaches of the Yellow River was below the global average level. Compared with the other plant species, Phragmites australis exhibited the highest N resorption efficiency (NRE) in the three types of wetlands. In riparian wetland and depressional wetland, woody plants demonstrated higher NRE and P resorption efficiency (PRE) than herbaceous plants. In floodplain, herbaceous plants surpassed woody plants in PRE and K resorption efficiency (KRE). In riparian wetland and floodplain, NRE and PRE of grasses were higher than those of forbs. From the perspective of efficient utilization of nutrients, woody plants had growth advantages in riparian wetland and depressional wetland, while grasses exhibited competitiveness in floodplain. Compared with other wetland types, depressional wetland showed the highest community NRE and PRE due to its lowest soil pH and highest electrical conductivity and organic carbon content. Soil electrical conductivity, organic carbon, and hydrolyzed N contents influenced nutrient resorption efficiency of woody plants, while soil water content and available P affected that of herbaceous plants. Soil organic carbon and hydrolyzed N contents were the main factors influencing nutrient resorption efficiency of grasses, while soil pH, electrical conductivity, organic C, and hydrolyzed N contents were the primary factors affecting that of forbs.
