摘要: 随着城镇化的不断发展，人类工程活动引发了一系列地质灾害问题，地质灾害每年造成的人员伤亡和经济损失不容忽视。本文构建了城镇化与地质灾害系统指标体系，运用熵权-TOPSIS方法，利用耦合协调度公式对我国2000—2013年的城镇化-地质灾害数据进行分析，研究城镇化与地质灾害的耦合协调关系。研究发现，2003—2013年我国城镇化与地质灾害的协调发展状态逐渐改善,我国地质灾害防治工作取得了良好的成效。Abstract: With the development of urbanization, human engineering activities caused a series of geo-hazards, which caused a huge casualties and economic. This paper constructs the urbanization and the geo-hazards index system, using the TOPSIS method to analyze the coupling relationship between urbanization of geo-hazards based on data during 2003-2013. The study found that the coordinated relationship between urbanization and geological disasters in China gradually improved in 2000-2013. The prevention and control of geo-disasters has achieved good results in China.
