摘要：近年来我国各地区地质灾害频繁发生,越来越严重地威胁到人民生命财产安全。因此,开展对地质灾害的研究具有重要的理论意义和实践价值。湖北省是我国地质灾害多发的省份之一，统计研究湖北省地质灾害与植被类型的关系, 对全省的防灾减灾工作有重要的指导意义。研究表明：植被类型不是影响湖北省地质灾害发育关系的主导因素，地质灾害发育强度与灾害点区域实际植被覆盖率有关，这也是造成植被类型与地质灾害发育关系统计分析资料中与实际有差异的原因。

In recent years, the regional geological disasters occurred frequently in our country, seriously threaten people's life and property safety. Therefore, to carry out the study of geological disasters has important theoretical significance and practical value. Hubei province is one of geological disaster-prone provinces in our country, statistics and studies on relationship between vegetation types and geological disasters in Hubei Province, to the province's disaster prevention and mitigation work has important significance. Research shows that vegetation types is not dominant factors of geological hazards in Hubei Province, intensity of geological hazards and actual vegetation cover of the disaster region, which contributes to statistical analysis of the relationship between vegetation types and geological hazards information and the actual cause of the difference.

一、引言

近年来关于地质灾害孕灾机理及地质灾害综合防治研究，已经成为环境地质学领域的前沿课题和学术界研究的热点,防灾减灾已经成为各级政府的重要职责。本文通过对湖北省植被类型与地质灾害发育关系展开研究,希望为湖北省地质灾害的预警预报、防治处理等提供可靠的理论依据。

二、湖北地质灾害与植被的关系

湖北是我国南方重点林区省份之一，林业用地占全省国土总面积的46.4%，植被覆盖率较高。根据湖北植被与灾点图，将我省植被覆盖类型划分为针叶林、阔叶林、针阔混交林、灌木林、疏林、竹林、经济林、荒山荒地、农业植被、其他土地等10类植被类型。湖北省地质灾害与植被类型关系详见表1。
