日照市地质灾害现状及防治建议

Present Condition of Geological Disasters Its Prevention and Control Suggestions in Rizhao City

摘要:

日照市地质灾害隐患点共计90处，灾害规模以小型为主。利用地质灾害危害程度评价、地质灾害稳定性、危险性评价及地质灾害易发程度综合分区评价，查明了地质灾害点分布位置，将地质灾害点的基本单元格进行现状、潜在地质灾害强度分析，其他基本单元格进行潜在地质灾害强度分析，确定各基本单元格易发程度。通过MapGIS软件，将相同易发程度的基本单元格合并连接成区，将地质灾害易发程度划分为高易发区、中易发区、低易发区，依据地质环境条件、地质灾害发育现状、灾害变化趋势、灾害危害特征，划分为重点、次重点和一般防治区，提出详细的地质灾害防治目标及对策建议，为日照市开展地质灾害预警预报示范区的建设工作提供了技术支撑。

Abstract:

There are 90 potential geological hazards in Rizhao city, and the scale of the hazards is mainly small. Based on the evaluation of hazard degree, stability, risk and vulnerability degree of geological disasters, the distribution position of geological disaster points is found. The basic units of geological disaster points have been analyzed for current situation and potential geological disaster intensity, and the other basic units have been analyzed for potential geological disaster intensity to determine the vulnerability degree of each basic unit. Through MapGIS software, basic units of the same prone degree are combined and connected into areas, and the prevention degree of geological disasters is divided into high prevention area, medium prevention area and low prevention area. According to geological environment conditions, development condition of geological disaster, disaster change trend and disaster hazard characteristics, geological disasters are divided into key, sub key and general prevention areas, and the detailed geological disaster prevention and control objectives are proposed The countermeasures and suggestions provide technical support for the construction of geological disaster early warning and prediction demonstration area in Rizhao city.
