摘要

城市地区的快速扩张导致了土地利用的重大变化，影响了当地的气候系统，特别是通过地表温度的上升。本研究利用大地遥感卫星图像和先进的地理信息系统技术，分析了伊朗萨里 10 年间地表温度的变化，研究了城市土地利用变化的时空动态及其对气温模式的影响。结果表明，10 年间平均 LST 上升了 3 °C，最高温度从 53 °C上升到 56 °C。LST 出现了明显的梯度变化，离土地利用变化点较近的地区气温上升幅度较大。与交通基础设施距离越远，降温效果越强，LST 明显降低。相反，距离花园和绿色基础设施越远，LST 越高。这些发现强调了土地利用转型在缓解或恶化城市地表温度方面的关键作用。

Distance matters: Quantifying the influence of urban land use change and development proximity on land surface temperature in Sari, Iran

The rapid expansion of urban areas has led to significant land use changes, affecting local climate systems, particularly through an increase in Land Surface Temperature. This study investigates the spatio-temporal dynamics of Urban Land Use Changes, and its impact on temperature patterns, using Landsat imagry and advanced GIS techniques to analyze changes in LST over 10 years in Sari, Iran. The results indicate 3 °C increase in average LST over 10 years, with maximum temperatures rising from 53 °C to 56 °C. A clear gradient in LST was observed, with areas closer to the spots with land use change experiencing more temperature increase in the temperature. The further distance to transportation infrastructure showed the strongest cooling effect, with proximity reducing LST significantly. Conversely, increased distance to gardens and green infrastructure were associated with higher LST. These findings emphasize the critical role of land use transformation in mitigating or worsening urban surface tempreature.

期刊介绍： The ultimate aim of Ecological Indicators is to integrate the monitoring and assessment of ecological and environmental indicators with management practices. The journal provides a forum for the discussion of the applied scientific development and review of traditional indicator approaches as well as for theoretical, modelling and quantitative applications such as index development. Research into the following areas will be published. • All aspects of ecological and environmental indicators and indices. • New indicators, and new approaches and methods for indicator development, testing and use. • Development and modelling of indices, e.g. application of indicator suites across multiple scales and resources. • Analysis and research of resource, system- and scale-specific indicators. • Methods for integration of social and other valuation metrics for the production of scientifically rigorous and politically-relevant assessments using indicator-based monitoring and assessment programs. • How research indicators can be transformed into direct application for management purposes. • Broader assessment objectives and methods, e.g. biodiversity, biological integrity, and sustainability, through the use of indicators. • Resource-specific indicators such as landscape, agroecosystems, forests, wetlands, etc.
