Abstract

This study examines the spatiotemporal changes in land use land cover (LULC) from 1990 to 2023 in the Islamkot subdistrict of Tharparkar, Pakistan, an area known for its vast coal reserves and environmental challenges. A change detection analysis was performed using the maximum likelihood supervised classification method, and a Normalized Difference Vegetation Index (NDVI) analysis was conducted to evaluate vegetation variations. The findings indicate significant changes in land cover patterns: settlement, vegetation, water bodies, and mining areas increased by approximately 3.02%, 20.2%, 3.8%, and 0.9%, respectively, while bare land decreased by 27.9%. The primary drivers of these changes were identified as mining activities and precipitation variations. These results provide a foundation for informed land use planning, conservation efforts, and regional sustainable development strategies.

荒漠地区土地利用、土地覆盖变化检测及归一化植被指数的时空评价

本研究考察了1990年至2023年巴基斯坦塔帕卡尔（Tharparkar）伊斯兰科特（Islamkot）街道土地利用和土地覆盖（LULC）的时空变化，该地区以其巨大的煤炭储量和环境挑战而闻名。采用最大似然监督分类法进行变化检测分析，采用归一化植被指数（NDVI）分析评价植被变化。结果表明，土地覆盖格局发生了显著变化，聚落、植被、水体和矿区分别增加了约3.02%、20.2%、3.8%和0.9%，裸地减少了27.9%。这些变化的主要驱动因素被确定为采矿活动和降水变化。这些结果为明智的土地利用规划、保护工作和区域可持续发展战略提供了基础。

期刊介绍： Rangeland Ecology & Management publishes all topics-including ecology, management, socioeconomic and policy-pertaining to global rangelands. The journal''s mission is to inform academics, ecosystem managers and policy makers of science-based information to promote sound rangeland stewardship. Author submissions are published in five manuscript categories: original research papers, high-profile forum topics, concept syntheses, as well as research and technical notes. Rangelands represent approximately 50% of the Earth''s land area and provision multiple ecosystem services for large human populations. This expansive and diverse land area functions as coupled human-ecological systems. Knowledge of both social and biophysical system components and their interactions represent the foundation for informed rangeland stewardship. Rangeland Ecology & Management uniquely integrates information from multiple system components to address current and pending challenges confronting global rangelands.
