Abstract:: The degradation and desertification of grassland in Zoige wetland lead to a decline in grassland productivity,environmental deterioration and reduction in biodiversity,which threaten the region’s ecological environment and the sustainable development of regional economy.Based on previous studies and data collected during field investigation,we analyze the causes of grassland degradation and desertification and come to a conclusion:the grassland degradation and desertification in Zoige wetland are influenced by human activities and natural factors.Natural factors are the natural background,which cause large-space and large-span grassland degradation and desertification.However,natural factors are not dominant factors at present,which only to make deterioration of the ecological environment,marsh degradation,and grassland desertification possible.Human’s intense activities in recent decades,such as overgrazing,draining swamps,are the main reasons which lead to the deterioration of the ecological environment and grassland degradation and desertification.It is necessary to formulate effective conservation and restoration measures based on the law of nature.
