This study evaluates land use/cover changes and urban expansion in Lahore, Pakistan from 2000 to 2020 using satellite images and socio-economic data. Spatial and temporal dynamics of land use/cover changes were quantified using five Landsat images, a supervised classification algorithm post-classification change detection and the intensity analysis technique in GIS. Landsat images 2000, 2005, 2010, 2015 and 2020 were classified into four dominant land use categories in the study area: built up area, agricultural land, barren land and water bodies. The intensity analysis of time interval revealed that the annual change rate during 2000–2005, and 2010–2015 was 28.76% and 16.45% respectively, while during the 2005–2010 and 2015–2020 was 11.49% and 6.04%. The transition level of intensity analysis indicated that the built-up area is expanded at agricultural land and gained area 886 km² and 861 km² in the period from 2000 to 2005, and 2010–2015, respectively. The built up area significantly growth from 22.99% to 47.17% of total study area 2000 and 2020 respectively. The driving force behind this change was economic development and population growth and climate change. The rapid population growth and rapid urbanization resulted in a wide range of environmental impacts, including degraded habitat quality.

本研究使用卫星图像和社会经济数据评估了 2000 年至 2020 年巴基斯坦拉合尔的土地利用/覆盖变化和城市扩张。土地利用/覆盖变化的时空动态使用五张 Landsat 图像、一种监督分类算法分类后变化检测和 GIS 中的强度分析技术进行量化。Landsat 影像 2000、2005、2010、2015 和 2020 在研究区被分为四个主要的土地利用类别：建成区、农业用地、贫瘠土地和水体。时间区间强度分析表明，2000-2005年和2010-2015年的年变化率分别为28.76%和16.45%，而2005-2010年和2015-2020年的年变化率为11.49%和6.04%。2000 年至 2005 年和 2010 年至 2015 年期间分别为²和 861 km ²。建成区面积从2000年和2020年分别占研究总面积的22.99%显着增长到47.17%。这种变化背后的驱动力是经济发展、人口增长和气候变化。快速的人口增长和快速的城市化导致了广泛的环境影响，包括栖息地质量下降。
