地理信息技术在森林资源测绘、监测和管理方面发挥着积极作用。地表森林覆盖的变化及其分析对于理解自然现象与生物体，特别是人类之间的联系和相互作用至关重要。森林砍伐也是全球变暖的主要原因，是温室效应增强和气候变化的根源之一。本研究是基于3S技术在森林覆盖面积内的LU/LC变化的评估在达尔马野生动物保护区（DWLS）贾姆谢德普尔贾坎德邦，印度。使用高分辨率卫星数据（SD）精确研究了2009年，2011年，2013年，2015年和2016年森林覆盖变化的运动。人们注意到，由于轮垦、森林火灾、将森林植被转变为耕地/裸地以及村民侵占森林地区的定居点正在迅速增加;因此，正在发生毁林现象。研究结果表明，3S技术在森林更新、规划、管理等方面具有一定的应用价值。
Geo-informatics technology has dynamic role in mapping, monitoring and management of forest resources. The transformation of forest cover and its analysis on the earth’s surface are essential for understanding the associations and interactions between natural phenomena and living organism, especially human. Also deforestation is a major reason for global warming and one of the origin keys for the enhancement of greenhouse effect and climate change. The present study is grounded on the 3S technology in assessment of LU/LC changes within the forest cover area in Dalma Wildlife Sanctuary (DWLS) Jamshedpur-Jharkhand, India. The movement of forest-cover variation over the years 2009, 2011, 2013, 2015 and 2016 is precisely studied using high resolution Satellite Data (SD). It is noted that, due to shifting cultivation, forest fire, and conversion of forest cover into crop land/bare land and settlement encroachments in forest region by villagers are rapidly increasing; as a result deforestation is taking place. It is predicted that the study would demonstrate the effectiveness of 3S technology in forest renovation, planning and management.
