Causes of the Desertification in Hulunbuir Prairie and Its Prevention and Control Measures
Maintaining the ecological safety of China is strategically significant as a particular example, consider the protection and conservation of the ecosystem of Hulunbuir Prairie in Chinas northern region. A lengthy period of development and excessive utilization coupled with two decades of drought in Hulunbuir Prairie has brought about varying degrees of damage to Hulunbuir Prairie and rapid grassland desertification. This paper analyses the Hulunbuir Prairie desertification and its causes, concluding that desertification has been aggravated by harsh natural conditions, along with human factors such as inefficient use of resources, overgrazing, unauthorized cultivation, and unlawful herbal medicine collection at Hulunbuir Prairie. We also show that thin soil layers are potentially dangerous contributing factors in the desertification of Hulunbuir Prairie. Furthermore, we propose vanous measures to prevent and control the desertification of Hulunbuir Prairie, including laws to supervise and utilize grasslands, maintaining a balance between foraging and livestock, prohibiting grazing, suspending grazing, rotational grazing, more reasonable allocation of stock capacity, optimizing industrial distribution, constructing artificial pasture and forage crops, establishing a basic system to permanently protect grassland and pasture, and developing a mechanism for compensating grassland ecology and environmental management.
