Abstract:

Horqin Sandy Land, located at the southeast end of the agro-pastoral ecotone in North China, should have been a landscape of sparse forest grassland with abundant water and grass. However, it has become one of the most seriously desertified areas in the modern era, due to the fragile ecological environment conditions combined with the influence of climate change and unreasonable human activities. During the great practice of desertification prevention and control in China, Horqin Sandy Land has taken the lead in realizing the benign reversal of desertification. Whereas, the situation of desertification prevention and control in this region is still severe under the background of global change. This paper focused on the typical countermeasure model and its effectiveness achieved in the past decades of sand control and prevention in Horqin Sandy Land, summarized the action plans of various provinces and regions since the launch of the decisive battle against desertification in Horqin Sandy Land, discussed the main problems and challenges facing by sand control and prevention in the new period, and put forward targeted ecological sustainable restoration countermeasures. The aim was to provide scientific and technological support for the high-level protection and restoration of the ecological environment and high-quality economic and social development in the Horqin Sandy Land.

Key words: northern sand-wind area, sandy ecosystem, desertification prevention, desertification control model, ecological restoration
