摘要

土地是人类赖以生存的最宝贵的财富之一,有食物、纤维、药物、矿物质等。采石是支持社会经济发展和工业扩张的关键要素之一。遥感和地理信息系统在环境评估中发挥重要作用,不时监测采石场及相关活动。本研究旨在评估采石破碎活动(SQCA)对土地资源的影响。因此,采用2021年、2015年、2008年和2003年的矩阵变化分析进行变化检测。高分辨率谷歌Earth Pro图像用于评估采石场和相关活动引起的空间和时间变化,这些变化导致土地利用/土地覆盖变化。结果表明:采石场内和采石场周围18年的时间变化对土地利用/土地覆盖的动态变化有一定的影响。根据这项研究,破坏性的采矿活动在该地区有所增加。SQCA以农用地和荒地为主,研究期间分别减少了18.44%和59.89%。没有填海的废弃坑变成了废弃的池塘,使景观退化,对人类和生态系统构成危险。

Remote sensing and GIS based approach to evaluate the impact of stone quarrying and crushing activities on land resources
Abstract The land is one of the most treasures to support life, like food, fibre, medicine, and minerals, etc. Stone quarrying is one of the key elements which supports socio-economic development and industrial expansion. RS and GIS play an important role in environmental assessment to monitor the stone quarries and related activities for time to time. The present study was carried out to evaluate the impact of stone quarrying and crushing activities (SQCA) on land resources. Therefore, matrix change analysis of 2021, 2015, 2008 and 2003 were used for change detection. High-resolution Google Earth Pro images were used for the assessment of spatial as well as temporal changes caused by stone quarries and associated activities, which result in land use/land cover changes. The results show that the temporal changes in and around the quarrying sites over 18 years have contributed to dynamic changes in land use/ land cover. According to the study, damaging mining operations have grown in the area. SQCA are mostly carried out on agricultural land as well as wasteland, which decreases about 18.44% and 59.89% during the study period. Abandoned pits left without reclamation converted to derelict ponds degrading the landscape and becoming dangerous for humans and the ecosystem.
