Abstract

Abstract

In recent years, with the aggravation of warming and humidification in the Qinghai-Tibet Plateau, regional rainfall increase and extreme rainfall weather happened frequently, unexpected geo-hazards in North & South Mountains area of Xining City are frequently and massively increasing year by year, especially the landslide and collapse disasters, which cause serious casualties and economic losses, and seriously threaten the safety of residents, infrastructure and greening facilities in Xining City. In order to actively deal with the severe geo-hazards situation in the area, ensure the safety of residents' life and consolidate the hard-won greening achievements, the occurrence, distribution and influence factors of geo-hazards in the area in the past 18 years are analyzed deeply, the key prevention period, key prevention area, influence on green area and later prevention suggestions are put forward.
- landslide /
- influential factors /
