2001-2023年安徽省植被NDVI时空变化特征及驱动力分析
Spatiotemporal Characteristics and Driving Forces of Vegetation NDVI in Anhui Province from 2001 to 2023
摘要
Abstract
Using MODIS NDVI data from 2001 to 2023,this study analyzed the spatiotemporal distribution and future change trends of NDVI in Anhui Province using linear regression,trend analysis,and Hurst index analysis.The driving forces were explored using the geographical detector.The results show that:(1)From 2001 to 2023,NDVI in most areas of Anhui Province showed an increasing trend,with the temporal change rate following the pattern central>southern>northern Anhui,while the spatial distribution pattern was southern>northern>central Anhui.(2)During this period,NDVI of vegetation in Anhui Province was dominated by an improving trend,covering about 45.15%of the province.(3)The Hurst index indicated that future interannual variation in NDVI will not be consistent with the 2001-2023 interannual changes in NDVI,with the dominant trend shifting from increasing to decreasing.(4)Geographical detector results for 2001,2005,2010,2015,and 2020 show that soil type had the strongest explanatory power,and the interaction between night-time light index and soil type showed the strongest explanatory power in interaction detection.This study explores the long-term change trends driving forces of NDVI in Anhui Province,providing a reference for future ecological protection.关键词
