摘要
汉江流域(湖北段)地质灾害的发育与其独特的孕灾地质环境条件密切相关,不同的孕灾地质条件造就了流域内地质灾害发育的差异性特征。国内尚未对汉江流域(湖北段)地质灾害作系统研究工作,仅对汉江流域上游(湖北段)丹江口库区地质灾害作过大量基础性工作。据汉江流域(湖北段)地质灾害调查数据统计,流域内地质灾害共计发育7024处,地质灾害类型主要为滑坡与不稳定斜坡,其次为崩塌与地面塌陷;泥石流、地裂缝、地面沉降相对不发育,本文以汉江流域(湖北段)地质灾害发育规律综合研究项目(项目编号KJ2016-11)为基础,对汉江流域(湖北段)孕灾地质环境背景与地质灾害发育关系进行探索研究,总结地质灾害发育特点,为地质灾害防治提供依据。
The development of geological disasters in the Han River Basin (Hubei section) is closely related to its unique geological environment conditions, and different geological conditions contribute to the differential characteristics of geological disaster development within the basin. There has been no systematic research on geological disasters in the Han River Basin (Hubei section) in China, and only a large amount of basic work has been done on geological disasters in the Dan-jiangkou Reservoir area in the upper reaches of the Han River Basin (Hubei section). According to the survey data of geological disasters in the Han River Basin (Hubei section), a total of 7024 geological disasters have developed in the basin. The main types of geological disasters are landslides and unstable slopes, followed by collapse and ground subsidence;Debris flow, ground fissures, and land subsidence are relatively underdeveloped. Based on the comprehensive research project on the development laws of geological disasters in the Han River Basin (Hubei section) (project number KJ2016-11), this article explores and studies the relationship between the geological environment background and geological disaster development in the Han River Basin (Hubei section), summarizes the characteristics of geological disaster development, and provides a basis for geological disaster prevention and control.
