摘　　要：为了查明滦县地质灾害的发育类型、分布及影响因素,在地质调查的基础上采用GIS技术和遥感影像分析方法,查明了滦县地区地质灾害发育现状并进行了该县地质灾害风险区划。研究结果表明,该区的西北部和东北部山区主要发育崩塌、滑坡、泥石流地质灾害类型,而较严重的地面塌陷灾害的分布情况与铁矿开采和灰岩分布密切相关。该成果对滦县地区进行防灾减灾部署和经济建设规划具有一定的借鉴意义。In order to find out the type, distribution and influence factors of geological disaster in Luanxian County, with GIS technique and remote sensing image analysis method, this paper deduces the development status of geological hazard and carri＇es out zoning of geological hazards risk in this region. The results show that the geological disaster types of collapse, landslide and debris flow mainly distribute in the northwest and northeast of the county, and the distribution of more severe ground subsidence disaster is closely related to the iron ore mining and limestone distribution. The result can provide a reference to making out the deployment of disaster prevention and mitigation and economic construction plan in Luanxian County.
