摘要
资源环境的保障程度直接影响中国城市化的速度与质量,制约着城市化的可持续发展。运用相关分析和冗余分析方法,研究2014年全国省会城市生活资源消耗和污染排放的主要影响因素。结果表明:1)中国省会城市生活资源消耗的主要影响因素是气候(解释变异量为0. 40),其次是经济发展水平(0. 14)和城市规模(0. 11)。2)污染排放的主要影响因素是城市规模(解释变异量为0. 21),其次是经济发展水平(0. 17)和气候(0. 16)。因此,针对城市资源消耗和污染排放的影响因素,制定适宜的资源开发和环境治理政策,对中国城市的可持续发展具有重大意义。
The guarantee of the resource and environment directly affects the speed and quality of China’s urbanization and restricts the sustainable development of urbanization.Based on the correlation analysis and redundancy analysis,we studied the main factors influencing urban living resource consumption and pollution emission.The results are showed as follows.1)The main influencing factors on the consumption of living resource in China’s provincial capital cities were climate(the explained variation being 0.40),followed by economic development level(0.14)and urban scale(0.11).2)The urban scale was the main influencing factor on pollution emission(the explained variation being 0.21),followed by economic development level(0.17)and climate(0.16).Therefore,it is of great significance to the sustainable development of China’s cities to formulate appropriate policies of resource development and environmental governance in view of the factors affecting urban resource consumption and pollution emission.
