MAO Zhengjun, NI Wankui, YANG Xiaohua, et al. Formation Conditions and Development Characteristics of Geological Hazards in Pengyang County of Ningxia Hui Autonomous Region[J]. Bulletin of Soiland Water Conservation, 2010, 29(5): 68-72.DOI:
Pengyang County is in extraordinarily severe situation in Ningxia Autonomous Region.Through the analysis of the data of regional geological environment
a detailed investigation of geological hazards in Pengyang County is completed by means of remote sensing interpretation and ground investigation
in the manner of the combination of point
line
and area surveying.Results from the investigation show that landslide
collapse
and unstable slope are the main types of geological hazards in the county
with the typical characteristics of geological hazards in loess region.They present zonal and concentrated features in view of temporal and spatial distribution.Landscape
stratum structure
rainfall
and human engineering activity are considered as the main formation conditions of geological hazards.
