Rapid urbanization has become a major urban sustainability concern due to environmental impacts, such as the development of urban heat island (UHI) and the reduction of urban security states. To date, most research on urban sustainability development has focused on dynamic change monitoring or UHI state characterization, while there is little literature on UHI change analysis. In addition, there has been little research on the impact of land use and land cover changes (LULCCs) on UHI, especially simulates future trends of LULCCs, UHI change, and dynamic relationship of LULCCs and UHI. The purpose of this research is to design a remote sensing-based framework that investigates and analyzes how the LULCCs in the process of urbanization affected thermal environment. In order to assess and predict the impact of LULCCs on urban heat environment, multitemporal remotely sensed data from 1986 to 2016 were selected as source data, and Geographic Information System (GIS) methods such as the CA-Markov model were employed to construct the proposed framework. The results showed that (1) there has been a substantial strength of urban expansion during the 40-year study period, (2) the farthest distance urban center of gravity moves from north-northeast (NEE) to west-southwest (WSW) direction, (3) the dominate temperature was middle level, sub-high level, and high level in the research area, (4) there was a higher changing frequency and range from east to west, and (5) there was a significant negative correlation between land surface temperature and vegetation and significant positive correlation between temperature and human settlement.

RS和GIS支持的城市LULC和UHI变化模拟和评估

由于环境影响,例如城市热岛(UHI)的发展和城市安全状态的减少,快速的城市化已成为关注城市可持续发展的主要问题。迄今为止,关于城市可持续发展的大多数研究都集中在动态变化监测或UHI状态表征上,而关于UHI变化分析的文献很少。此外,关于土地利用和土地覆被变化(LULCC)对超高强度城市影响的研究很少,特别是模拟了低密度高碳国家的未来趋势,超高强度城市的变化以及低密度高碳国家与超高强度城市的动态关系。这项研究的目的是设计一个基于遥感的框架,该框架调查和分析城市化过程中的LULCC如何影响热环境。为了评估和预测LULCC对城市热环境的影响,选择1986年至2016年的多时相遥感数据作为源数据,并采用CA-Markov模型等地理信息系统(GIS)方法来构建所提出的框架。结果表明:(1)在40年的研究期内,城市扩张具有相当大的力量;(2)距离城市重心最远的距离是从东北偏北(NEE)向西南偏西(WSW)方向移动,(3)研究区的主要温度为中,次高,高水平;(4)从东到西的变化频率和变化范围较高;(5)呈显着的负相关地表温度与植被之间的关系以及温度与人类居住之间的显着正相关。
