[Objective] In order to clarify the effect of restoration on soil physicochemical properties and distribution of soil inorganic phosphorus at Dianchi lake catchment, to assess the effects of restoration on soil recover and environment. [Methods] The way of space-time substitution was used. Soil physicochemical properties and phosphorus fractions were compared between vegetable field and riparian buffer in soil profile at Dianchi lake catchment. Three areas with similar restoration type were used to compare with each other in the Dianchi riparian. [Results] After the 3 years since restored from field, shallow groundwater level was shallower in Niulian buffer than in Niulian field. The content of soil organic carbon and nitrogen were more in Niulian buffer than in Niulian field, the content of total phosphorus, Olsen-P, Al-P and Fe-P were less in Niulian buffer than in Niulian field, the content of O-P was more in Niulian buffer than in Niulian field. The shallow groundwater level in Haigeng buffer was similar to shallow groundwater level in Haigeng field, but compared with Haigeng field, soil physicochemical properties and soil inorganic phosphorus fractions had no significant change in Haigeng buffer. Compared with Xinglong field, content of soil organic carbon and nitrogen decreased significantly in Xinglong buffer. The restoration had no significant effect on soil restoration and soil inorganic phosphorus fractions directly in 3 years. But changing shallow groundwater level had a significant effect on soil physicochemical properties and distribution of soil inorganic phosphorus directly in 3 years. [Conclusion] Buffer and vegetable field had risk of phosphorus leaching loss in the Dianchi riparian. Restoration enhanced the speed of phosphorus leaching and reduced potential leaching risk through raising shallow groundwater level.
