西南喀斯特地区植被覆盖度时空变化特征及其驱动因子分析
Analysis of Spatial and Temporal Change Characteristics in Vegetation Coverage and Its Driving Factors in Southwest Karst Region
摘要
Abstract
Using NDVI,precipitation,temperature and sunshine data,the spatiotemporal distribution pattern of vegetation coverage in the Southwest Karst region from 2000 to 2020 was analyzed through linear regression method,and the changing trend was analyzed using partial de-rivatives and other methods.The contributions of climatic factors and human activities to changes in vegetation coverage were quantified,and the driving factors were explored.The result showed that vegetation coverage in the Southwest Karst region exhibited a distinct spatial pattern,with higher coverage in the southern and mountainous areas compared to the northern and plain regions.From 2000 to 2020,vegetation coverage demonstrated a fluctuating upward trend,with high-coverage areas increasing from 1.296 million to 1.314 8 million square kilometers—an ex-pansion of 18 800 square kilometers.Temperature was identified as the primary driver of vegetation coverage growth,showing a strong correla-tion of 65.67%.关键词
