我国城镇化与地质灾害耦合协调度分析

利用TOPSIS方法以及耦合协调度公式,对我国31个省份的城镇化与地质灾害的耦合协调关系进行分析,以评价两者耦合协调发展的趋势。研究表明,近年来我国各省份的城镇化与地质灾害的协调发展状态逐渐改善,大部分省份都改变了城镇化与地质灾害系统失调的状态,实现了两者的协调发展。通过绘制不同年份各省的耦合协调度等级分布图发现,城镇化与地质灾害的耦合协调关系还呈现出一定的空间特征,即西部地区的耦合协调度普遍高于中部和东部地区,且耦合协调度的上升逐渐由西部向中东部扩展。地灾防治理念的转变、长效投入机制的构建以及重点区域重点规划等是关系转变的主要原因。

COUPLED COORDINATION DEGREE BETWEEN URBANIZATION AND GEOLOGICAL HAZARDS IN CHINA

This paper uses TOPSIS and coupled coordination degree formula to study  the coupled coordination degree between urbanization and geological hazards in 31  provinces of China, and the developing trend of the coupled coordination degree,  with the results showing an improving coordinated development, reaching a  coordinated status from out of coordinating in most provinces. Coupled  coordination degree level distribution map shows some spatial features that the  coupled coordination degree in the western China is universally higher than in  the central and eastern, and is rising from the western to the central eastern.  Reasons arise from a conversion in geological hazards prevention and control  concept, establishment of long-term input mechanism and key regional planning.  
