Abstract
Understanding the spatial-temporal dynamics of vegetation and its driving mechanisms is important for regional ecological restoration. Based on Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) data, climate and human factors, vegetation dynamics and its driving factors were analyzed in the Yellow River Delta from 2000 to 2016. The result showed that NDVI experienced a significant increase trend over the past 17 years, and at a rate of 0.007 year-1. The study area was mainly covered with high and extremely high NDVI (62.87%), which was mainly distributed in the southwest, middle, and northeast of the Yellow River Delta. The area of stable vegetation regions was higher than that of vulnerable vegetation regions in the study area. The area of degraded vegetation accounted for 13.97% of the study area, and the slightly and severely degraded vegetation was the main degraded vegetation types in the Yellow River Delta. Compared to other vegetation types, the area of degraded grassland was the largest. Areas of severely degraded vegetation were mainly distributed in the north and south of the Yellow River Delta, particularly in Hekou and Dongying. NDVI was significantly affected by growing season precipitation and population in the Yellow River Delta. In the future, considerable attention should be paid to the degraded regions especially in coastal areas in the Yellow River Delta.
