土地利用变化与碳排放效应的库兹涅茨曲线假说及验证以徐州市为例

摘要:整个全球气候的变化对城市的生态环境系统以及我们所提出的可持续发展战略产生了巨大的冲击和影响，城市的空间形态变化影响着碳排放，因此重新规划城市土地利用方式及内部联系可以有效地降低碳排放强度。本论文利用徐州市2007-2014年的土地变更数据和碳能源消耗数据，分析了徐州市8年间建设用地、耕地、林地和草地的面积变化特征以及相对应的碳排放特征，并构建了建设用地、耕地、林地和草地用地比例与徐州市的碳排放强度之间的库兹涅茨曲线模型，对徐州市建设用地、耕地、林地和草地的变化与碳排放强度的相关关系进行了验证研究，验证了建设用地、耕地、林地和草地的变化与碳排放强度之间存在库兹涅茨曲线模型。以此提高城市空间的合理布局，建立集约化和高效化土地利用体系，提高可持续发展的生态环境系统。91096

Abstract: The entire global climate change on the city's ecological environment system, and we have put forward the sustainable development strategy has a huge impact and influence, urban space form changes affect the carbon emissions, thus to planning and urban land use mode and internal contact can effectively reduce carbon emissions intensity。 With the rapid development of the city's economy and industrialization, land use is constantly changing。 This paper use of Xuzhou city land change data in 2007-2014 and carbon energy consumption data, analyzes the Xuzhou eight years of construction land, cultivated land, forest land and grassland area of variation characteristics and the characteristics of the corresponding carbon emissions, and constructs the construction land, cultivated land, forest land and grass land proportion and Xuzhou city between the carbon intensity of Kuznets curve model, Xuzhou construction land, the change of cultivated land, forest land and grassland and the carbon intensity of validation studies were conducted for the relevant relations, verify the construction land, the change of cultivated land, forest land and grassland and carbon intensity between the existence of the Kuznets curve model。 In order to improve the rational layout of urban space, establish the system of intensive and efficient land use and improve the sustainable development of eco-environment system。

Keywords：Urban space form；Land use change；Kuznets curve； Carbon intensity
