- 摘要:
- 长汀县地质灾害类型有滑坡、不稳定斜坡、崩塌等，其中以滑坡为主。多数地质灾害点个体规模小，稳定性差，活动频繁，地质灾害发育具有明显的地域性与季节性分布的特点。该文主要阐述了长汀县地区地质灾害的类型、发育特征、时空分布规律，详细地分析了长汀县地质灾害的形成条件，得出了以下结论：地形地貌是该地区地质灾害形成的外在主要控制因素；地层岩性在一定程度上决定着地质灾害的发育程度，是其形成的内在主要控制因素；降雨和人类工程活动是地质灾害形成与发生的主要诱发因素。同时，提出了监测、避让搬迁、工程治理等防治措施，为当地的防灾减灾提供了科学的依据。
- Abstract:
- The principal types of the geological hazards in Changting County are: landslide which is predominant disaster, unstable slope, collapse and slumping. Most geological hazards are on small scale resulting from poor stability and frequent impact. It also reflects obvious regional and seasonal characteristics. This paper expounds the types of geological hazards in this region, their development characteristics and the discipline of spatial and temporal distribution, the detailed analysis of the formative conditions for geological hazards in Changting County. Conclusions were summarized as following: topography is the main controlling external factor in the formation of geological hazards in this region; in order to ascertain the extent, formation lithology is applied to determine the development degree of the geological hazards and is the main controlling internal factor in the formation of the geological hazards; rainfall and anthropogenic activities are the main precipitating factors on the formation and the occurrence of the geological hazards. Meanwhile, this paper proposes the control measures for monitoring, mitigation and relocation, engineering treatments in order to provide a sound scientific basis for the prevention and reduction of localized geological hazards.
