【摘要】：呼和浩特市作为我国北方干旱区主要核心城市之一,其在经济快速发展的同时,特别是城市化进程所带来的环境问题亦越来越受到多方关注。文中基于环境库兹涅茨曲线(EKC)理论,分析探讨了在1996-2015年时间序列内,呼和浩特市城市化与大气污染的曲线拟合相关性关系。结果表明:呼和浩特市现正处于城市化飞速发展时期,而在今后一段时期内这一趋势仍将延续;通过构建三次多项式模型发现,呼和浩特市城市化与大气污染的曲线拟合表现为"U型"的特殊曲线关系,其中可吸入颗粒物(PM10)为大气环境污染的主要贡献因子,属于典型的颗粒物型污染城市,即在城市化发展较为缓慢的初期,大气环境污染降低,而后随着城市化进程加快,经济持续快速发展,大气环境污染问题开始凸显,但行之有效的防治措施使得这种上升趋势并不十分显著。
[Abstract]:Hohhot is one of the main core cities in arid areas of northern China. With the rapid economic development, especially the environmental problems brought by the urbanization process, more and more attention has been paid to Hohhot. Based on the EKCtheory of environmental Kuznets curve, the relationship between urbanization and air pollution in Hohhot from 1996 to 2015 is analyzed and discussed. The results show that Hohhot is in the period of rapid development of urbanization, but this trend will continue for some time to come. The curve fitting between urbanization and air pollution in Hohhot shows a special curve relation of "U type", in which inhalable particulate matter (PM10) is the main contributing factor of atmospheric environmental pollution and belongs to a typical particulate pollution city. That is, in the early stage of the slow development of urbanization, the atmospheric environmental pollution decreases, then with the acceleration of the urbanization process and the sustained and rapid development of the economy, the problem of atmospheric environmental pollution begins to highlight. But the effective prevention and cure measure causes this kind of upward trend not very remarkable.
