Résumé
Grassland is an important part of the earth system and the largest ecosystem in the land area of China.My country has various natural grasslands of about 4×106km2,accounting for 41%of the country’s land area.Among them,Inner Mongolia grassland area is the most widely distributed,with a grassland area of 786,000 km2,accounting for19.65%of the national grassland area.As an important ecological protection function area in the ecological environment,Inner Mongolia grassland has an important position in the social and economic life of China.At present,more than 90%of the grasslands in the pastoral areas of Inner Mongolia have grassland degradation,desertification and salinization.The productivity of pastures has generally fallen by more than 50%,and The economic and ecological functions of grassland have been reduced.Therefore,the study of ecological protection and restoration of Inner Mongolia desert grasslands has become an important modern topic.In this paper,based on the previous research results,we take the concept of ecological priority and high quality development as the guideline,apply the theory of human-land relationship territorial system,use literature,fieldwork,in-depth interview,questionnaire survey,mathematical and statistical methods and GIS technology to explore the influence of the evolution of human-land relationship on ecological degradation in Wulatehou Banner,which is a desert grassland in Inner Mongolia in the past 70 years,and then analyze The study concluded the following conclusions.The study concludes that :(1)In the past 70 years,The evolution of human-land relations in Wulatehou banner has gone through three stages,the nomadic human-land harmony stage(50-58 a),the human-land"friction"stage under farming and fixed herding(58-83 a),and the human-land conflict stage under industrial and mining development(83 a to now),etc.(2)The disappearance of nomadic culture in the Wulatehou Banner,the reduction of grazing distance,and the reduction of grazing range are the main causes of pasture degradation.(3)Reclamation of grasslands unsuitable for cultivation generally results in the end of hitting food in the first year,reducing production in the second year,and turning into a sand beam in the third year.This is especially true in desert grasslands,where reclamation not only causes land desertification,but also depletes groundwater resources.(4)Water is the key to ecological and economic development.Desert grassland water engineering has caused irreversible and vicious effects to the ecological environmen
