Abstract:

Horqin Sandy Land is one of the four great sandy lands in northern China. Due to the relatively high level of precipitation and temperature conditions and the unique characteristics of civilization evolution, nomadic and farming civilization alternate development of history. In modern times, the rapid development of agricultural and husbandry production activities derived from the social change and population surge led to the continuous land degradation of Horqin Sandy Land in the past hundred years. The resulting phenomena such as low vegetation coverage and increased wind and sand activities, on the one hand, limit the development of regional agricultural and husbandry economy and the improvement of the living standards of farmers and herdsmen, on the other hand, lead to the deterioration of environmental quality, thus contradicting the demand for high-quality life. Under this background, the state and local governments have implemented a series of major projects, policies and regulations related to ecological restoration in Horqin Sandy land, and relevant institutions have carried out a series of fundamental studies and technology research and development demonstrations related to soil desertification process and ecological restoration in Horqin Sandy Land. In the past 3 decades, the desertified land in Horqin area has achieved effective reversal and sustainable recovery under the joint promotion of scientific theories, policies, regulations and major projects. This paper systematically reviews the research progress related to ecological restoration in Horqin Sandy Land in recent years, and makes a preliminary outlook based on the existing research basis and the major needs of national ecological civilization construction, combined with the current situation and trend of regional development, aiming to provide information support for the effective management and high-quality regional development of Horqin Sandy Land.

Key words: desertification, ecological restoration, ecological civilization, Horqin Sandy Land
