摘要

彭阳县是宁夏回族自治区地质灾害最为发育的县。在充分研究区域自然地质环境资料的基础上

以遥感解译结合地面调查为技术手段

采用点、线、面相结合的调查方式

完成了彭阳县地质灾害详细调查工作。调查研究结果表明

彭阳县地质灾害主要发育类型为滑坡、崩塌及不稳定斜坡

具有黄土地区地质灾害典型特征;从时空分布规律上来看

彭阳县地质灾害具有条带性与集中性;形成条件包括地形地貌、地层结构、降雨和人类工程活动。

Abstract

In the matter of geological hazards

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.
