Phosphorus is an important element of the wetland and agricultural ecosystems, and great attention has been paid to the movement and transformation of phosphorus speciation in soils. The Hani terrace, which is located in Yunnan, a province in southwest China, is unique with its typical mountainous landscape of forests, villages, man-made paddy wetlands and rivers. The aim of the research was to investigate the spatiotemporal distribution of various forms of phosphorus in the soils of Hani terrace wetland and find out its influencing factors. In view of that, this paper conducted a comprehensive analysis of the forms of phosphorus in the soils collected at different altitudes (the upper, middle, and lower terrace areas) and depths (0-20 cm, 20-40 cm, 40-60 cm, 60-80 cm) in the growing, harvest and fallow periods of paddy, respectively. The results indicated that (1) in the soils of Hani terrace wetland, the average content value of total phosphorus (TP) was 318.74 mg/kg and reached its peak in the harvest period. The average content value of inorganic phosphorus (IP) was the highest in the fallow period (85.95 mg/kg), generally presenting a deficiency of phosphorus in the wetland soils. (2) due to the impact of exogenous phosphorus input, iron/aluminum-bound phosphorus (NaOH-P) made up the largest part of IP and showed significant seasonal differences as regards its content (P<0.05). Whereas, the content of calcium-bound phosphorus (HCI-P) had no significant difference in each season (P>0.05), which was related to the ecological environment and geological background of the wetland. (3) Hani terrace wetland could intercept the movement of phosphorus, manifested in that the contents of various forms of phosphorus were generally higher in the upper terrace area and decreased with the decrease of altitude. In vertical soil profiles, the enrichment of phosphorus in different forms occurred in the 20-40 cm soil layer. (4) all the forms of phosphorus, except HCI-P, were negatively correlated with soil particle size in different soil layers. The TP and organic phosphorus (OP) were positively correlated with pH in different soil layers. There was significant negative correlation between soil total organic carbon (TOC) and different forms of phosphorus during the harvest period (P<0.05). Based on the findings summarized above, the research showed that the stereoscopic spatial structure of Hani terrace wetland and human activities could influence phosphorus distribution and cycling in the wetland ecosystem, which could provide a reference for the sustainable development of terrace wetlands.
