Abstract

Vegetation plays an essential role in ecosystem processes, including control of soil erosion and carbon and water cycles. This study examines sudden changes in vegetation in Jharkhand, India, from 2001 to 2018 using the Moderate Resolution Imaging Spectroradiometer (MODIS) Enhanced Vegetation Index (EVI) and Breaks For Additive Season and Trend (BFAST) algorithm. The results show that 69% of the land area experienced abrupt vegetation change. The main negative changes occurred in 2008, 2014, and 2015. Positive changes reached the peak in 2012 and 2013. Negative changes ranged from -0.4 to -0.001 while positive changes ranged from 0.001 to 0.4. The highest negative change was -0.1 to -0.05 and positive between 0.01 and 0.05. These findings emphasize significant environmental impacts and emphasize the need to improve soil and control to alleviate the ecosystem degradation and support sustainable development in Jharkhand.

基于MODIS evi的区域植被变化BFAST评价

植被在生态系统过程中起着至关重要的作用，包括控制土壤侵蚀和碳和水循环。本研究利用中分辨率成像光谱仪（MODIS）增强植被指数（EVI）和加性季节和趋势中断（BFAST）算法，研究了2001年至2018年印度贾坎德邦植被的突然变化。结果表明，69%的土地面积经历了植被突变。主要的负变化发生在2008年、2014年和2015年。积极的变化在2012年和2013年达到顶峰。负变化范围从-0.4到-0.001，而正变化范围从0.001到0.4。最大负变化为-0.1 ~ -0.05，最大正变化为0.01 ~ 0.05。这些发现强调了重大的环境影响，强调了改善土壤和控制以减轻贾坎德邦生态系统退化和支持可持续发展的必要性。
