To explore the litter decomposition characteristics in extreme arid regions, three types of leaves litter (Karelinia caspia, Alhagi sparsifolia and Populus euphratica) were selected as test objects. Using litter bag method, litter decomposition experiments were conducted in the desert area of the southern margin of Taklimakan Desert. The results showed that:(1)After one year decomposition in extreme arid areas, litter decomposition is mainly concentrated in May to September, the loss of organic matter is an important reason of weight loss; (2) For litter with high water soluble salt content, water soluble salt loss accounts for a higher proportion of weight loss; (3) Rainfall is an important factor affecting litter decomposition in extreme arid areas. The relationship between rainfall and the Pearson correlation of litter decomposition is significantly higher than between temperature and solar radiation.
