Abstract:: Soils from wetlands recovered from farmlands with different returning farmland to wetland (RFL) periods were sampled to analyze changes of the soil nitrogen and phosphorus in Anqing along the Yangtze River. The results showed that changes of soil nitrogen and phosphorus were significant after RFL. Soil total nitrogen content and available nitrogen content showed a increasing trend within the RFL period of 3~7 years, and then kept a stable situation during the RFL period of 7~21 years. Soil total phosphorus showed a declining trend with average decreasing rate of 11.62% during RFL period; soil available phosphorus content decreased within 9 years of RFL, and increased after 9 years of RFL. Soil phosphorus recovered slower than soil nitrogen after RFL, which indicated that soil phosphorus was the very important indicator for wetland soil ecological restoration.
