摘要
四川的地质灾害为我国发育最多、规模最大、类型最全、频率最高、危害最严重的地质灾害,在享有“天府之国”美誉的同时也享有“地质灾害博物馆”之称。地质灾害严重制约了四川省的经济发展。文章在广泛收集前人资料的基础上、重点研究了四川地质灾害在空间上、时间上的发育分布特征,研究分析了地质灾害的形成条件,诱发原因和发展趋势,结合地质灾害的危害首次划分了重力型、降雨型、人工型、复合型四种成灾摸式,同时根据四川地质灾害的发育特点,提出了行政、技术、综合治理的防治对策。
Sichuan Province is the great geological-hazard Province,where the geological hazard is of the largest scale,the most complete types,the highest-frequency occurrence and the severest damage,so Sichuan Province,called as'country in heaven',also has a name of'museum of geological hazards'.The geological hazard has severely restricted the economic deveolpment of Sichuan Province.Based on the accumulated data of the predeces-sors,the authors have mainly studied the growth and distribution characteristics of geological hazards in Sichuan Province in space and time,and analyzed the formation conditions,incentive factiors and development tendency;combining the harm degree of the geological hazard,the geological hazards have been classified into four hazard types:gravity type,rainfall type,manual type and compound type;at the same time,according to the growth characteristics of geological hazards in Sichuan Province,the countermeasures of adminstration,technology and comprehensive have been put for references.
