【Abstract】 The carbohydrate seasonal dynamic of plants under grazing stress in Stipa breviflora desert steppe were analyzed. The results showed that the carbohydrate contents of plants under different grazing stress weren’t the same all the time, and the seasonal dynamic of carbohydrate was significant. The dynamic of reducing sugar was severer than total sugar. The relationship between and plants reducing sugar growth was closer than that of total sugar.更多还原
