Abstract

Urbanization significantly influences the local climate of a city, giving rise to the Urban Heat Island (UHI) phenomenon and affecting the quality of human life. The UHI is characterized by elevated temperatures in urban areas, a condition exacerbated by the impacts of global warming and urban growth compared to the outlying regions, posing a significant urban challenge resulting from human activities. The present study focuses on Jhansi, with the aim of analysing the formation of UHI in the region. The research employs a multidimensional approach, which includes analysing the dynamic changes in land use land cover (LULC) and fluctuations in urban surface temperature in Jhansi as well correlation analysis is determined using remote sensing and meteorological data through geographic information system (GIS) analysis. The LULC was found to have an impact on the land surface temperature's (LST) spatial distribution. The built-up area was expanded from 7 % which is 25.13 km² in 2001 to 26 % which is 87.47 km² in 2021. Furthermore, because of urbanization, decreased greenery, conversion of natural surfaces to impervious structures and city growth, the LST values in the central region of the city in 2021 were higher than in 2001 and 2011. Moreover, crops and vegetation were found to have the lowest LST, followed by waterbodies. The findings also revealed that there was a 1.51 overall increase in UHI intensity from 2001 to 2021. These findings promote sustainable development by assisting policymakers and urban planners in developing efficient mitigation and adaptation plans that lessen the UHI effects. The study provides an in-depth understanding of the origins and growth of UHI within the specific context of Jhansi, providing new insight into the complex dynamics of the UHI issues. The resilience and sustainability of urban areas can be enhanced by employing this information as a foundation for thoughtful decision-making.

基于遥感和地理空间技术评估印度Jhansi土地利用、土地覆盖变化和城市化对城市热岛的影响（2001 - 2021）

城市化极大地影响了城市的气候，产生了城市热岛现象，影响了人类的生活质量。城市热岛的特点是城市地区温度升高，与外围地区相比，全球变暖和城市增长的影响加剧了这种情况，对人类活动造成的城市构成了重大挑战。本研究的重点是Jhansi，目的是分析该地区UHI的形成。该研究采用多维度方法，分析了Jhansi土地利用、土地覆盖和城市地表温度的动态变化，并通过地理信息系统（GIS）对遥感和气象数据进行了相关性分析。陆面温度变化对地表温度的空间分布有影响。建成区面积从2001年的7%（25.13平方公里）扩大到2021年的26%（87.47平方公里）。此外，由于城市化、绿化减少、自然地表向不透水结构转化以及城市发展，2021年城市中心地区的LST值高于2001年和2011年。农作物和植被的地表温度最低，水体次之。调查结果还显示，从2001年到2021年，热岛强度总体增加了1.51%。这些发现有助于决策者和城市规划者制定有效的缓解和适应计划，减轻热岛效应，从而促进可持续发展。该研究提供了对Jhansi特定背景下城市热岛的起源和发展的深入了解，为城市热岛问题的复杂动态提供了新的见解。通过利用这些信息作为深思熟虑决策的基础，可以增强城市地区的复原力和可持续性。
