皖南山区地质灾害发育规律与防治对策

Development characteristics and prevention measures of geological hazards in mountain area of southern Anhui Province

摘要: 皖南山区山高坡陡,是安徽省崩塌、滑坡地质灾害多发、频发、易发地区,也是安徽省地质灾害危害最严重的地区。研究结果表明,脆弱的地质环境是该地区地质灾害发育的基础,强降雨是主要诱因,人类工程活动是加剧地质灾害发生的主要因素。每年的六、七月份,在人类工程活动强烈地区,尤其是砂页岩和千枚岩分布地区,地质灾害呈集中、群发态势。开展地质灾害详细调查、提高地质灾害气象预报精度、减缓人类工程破坏强度、完善群测群防体系将是该地区有效防治地质灾害的主要措施。

Abstract: The mountain area of southern Anhui Province is the region where the mountains are high and the slops are steep,and it is an area where collapse,landslide and debris happened frequently,besides,it suffers the geological hazards most seriously in Anhui Province.The results of our study show that the fragile geological environment is the basis of the geological hazards while heavy rain is the main induction factor of collapses and landslides,and human engineering activities are the main factors wh...
