在进步主义时期,与轰轰烈烈的市政改革运动相呼应,美国城市也经历了一场大规模的城市环境改造运动。通过市政改革,美国城市完成了从传统政治向现代城市治理的转变;而通过城市环境改造,美国城市则完成了从传统的城市环境向现代城市环境的转变。本文试图利用环境史的研究方法,对进步主义时期美国城市的环境治理进行研究,以探究其中的得失与成败,从而为我国当前的城市环境治理提供借鉴。 In the period of progressiveism, in response to the vigorous municipal reform movement, the U.S. cities experienced a massive urban environmental reform movement. Through the municipal reform, the United States completed the transformation from traditional politics to modern urban governance. Through the urban environment reform, the American cities have completed the transformation from the traditional urban environment to the modern urban environment. This article attempts to make use of the research methods of environmental history to study the environmental governance of American cities during the progressing period so as to explore the pros and cons of them and thus to provide reference for the current urban environmental governance in our country.
