梅州市地质灾害特征及防治规划

Characteristics of Geological Disasters and Their Prevention Planning in Meizhou City

梅州市是典型的山区,是广东省崩塌、滑坡等地质灾害多发、频发、易发区。在对该市地质灾害进行系统调查的基础上,对地质灾害的特征和影响因素进行分析。研究表明,脆弱的地质环境是该地区地质灾害发育的基础,降雨是主要诱因,人类工程活动是造成地质灾害隐患的主要因素。针对梅州市的灾害分布情况及经济发展要求,对梅州市地质灾害进行全面规划,并进行了易发性分区;将梅州市分为地质灾害重点防治区、次要防治区和一般防治区;在把握预测性、前瞻性、动态性的原则上,将规划分为近期、中期和远期规划。最后,对该区地质灾害防治提出主要措施及建议:逐步建立地质灾害监测预报体系,提高防灾减灾能力;落实地质灾害防治责任制;工程措施与生物措施相结合的治理模式。

Meizhou City is a typical mountainous region, which is the multiple, frequent and prone area of geological disasters in Guangdong Province. The characteristics and influencing factors are analyzed based on the investigation of geological disasters. Results show that the fragile geological environment is the base of the geological hazards, while heavy rainfall is the main induction factor of geological disasters and human en- gineering activities are the main factors which aggravate the geological hazards. In view of the disaster distri bution and the economic development of Meizhou City, geological hazard control is comprehensively planned, and susceptibility zoning is completed. Meizhou City is divided into the key prevention region, secondary pre- vention region and general prevention region. Based on prediction, prospection and dynamic, the prevention planning is divided into short-term, medium-term and long-term planning. Finally, the main measures and recommendations are put forward for the prevention and control of geological disasters, such as gradually es tablishing a geological disaster monitoring and forecasting system, improving the ability of disaster preven tion and reduction, implementing geological disaster prevention responsibility system, and establishing engi- neering and biological measures combining the management mode.
