Abstract:: Surface soil pH, total and available nutrients of wet meadow under different grazing systems and water condition were studied through position experiment and constructed experiment. The results showed that effect of grazing and water regulation on wet meadow soil was complex. Soil pH and total nitrogen content were increased by pasturing prohibition and water improvement, while soil organic matter, total nutrients and available potassium content decreased. Available nitrogen content and its proportion in total nitrogen were improved under grazing condition, which were the highest under grazing and the lowest under pasturing prohibition. Available phosphorus content and its proportion in total phosphorus decreased under grazing condition, and increased under improved water condition.
