摘要
城市化与环境问题是当今世界人类所面临的热点问题。城市化与环境的耦合发展是社会不可避免的发展道路。通过建立城市化系统和环境系统的耦合指标体系,基于利用灰色关联度分析法、数学模型量算理论来计算喀什市城市化与环境的耦合度。结果表明:2005—2013年,喀什市城市化与环境耦合度分别为0.7417、0.7669、0.7838、0.8212、0.8047、0.8532、0.7949、0.776、0.7420。其中,2005年耦合度最低,2006年开始逐渐增高,到2010年达到最高,2005—2010年城市化与干旱区环境耦合度呈逐渐增加的趋势,2010—2013年耦合度呈逐渐减退趋势。城市化与环境之间存在"U"型曲线关系。
Urbanization and environmental problems are hot issues in the world today. The coupling development between urbanization and environment is the inevitable development path for the society. We set up the coupling index system of urbanization system and environment system. Based on the theory of coupling mathematical model of measurement between the city and the environment,as well as the coupling degree between urbanization and environmental system in Kashi from 2013 to 2005,two systems were identified in this paper. Results showed: from 2005 to 2013,the coupling degrees of urbanization and environment in Kashi were 0. 7417,0. 7669,0. 7838,0. 8212,0. 8047,0. 8532,0. 7949,0. 776,0. 7420 respectively,in which the lowest was in 2005 and the value increased gradually at the year of2006 and reach the maximum in 2010. From 2005 to 2010,the coupling degree of urbanization and arid area gradually increased,and the coupling degree from 2010 to 2013 decreased year by year. A "U " curve curvilinear relationship exists between urbanization and environment.
