2010-2022年江苏省植被覆盖变化特征与驱动力分析
Vegetation Coverage Change Characteristic of Jiangsu Province from 2010 to 2022 and Its Driving Factor Analysis
摘要
Abstract
Based on MODIS-NDVI data and associated meteorological data from 2010 to 2022,we analyzed the spatio-temporal distribution characteristics of NDVI in Jiangsu Province,and explored the impacts of meteorological factors and human activities on NDVI changes by applying methods such as linear trend regression analysis,variation coefficient analysis,correlation analysis,and residual analysis.The results indicate that①the multi-year monthly average NDVI in Jiangsu Province exhibits a bimodal pattern,with significant regional and seasonal differences in vegetation coverage.②NDVI changes are correlated with concurrent changes in temperature and precipitation,where temperature plays a decisive role in NDVI changes within the ecosystem of Jiangsu Province.③Human activities facilitate the positive development of vegetation ecosystem in Jiangsu Province,with the impact on vegetation distribution showing a decreasing trend of annual fluctuations.This study reveals that suitable temperature and precipitation,along with rational human activities,contribute to the increase of vegetation coverage.The government should focus on changes in extreme weather and refine human activity patterns to promote a positive cycle of the regional ecological environment.关键词
