Variation in Vegetation and Its Driving Force in the Middle Reaches of the Yangtze River in China

The temporal and spatial characteristics of vegetation in the middle reaches Yangtze River (MRYR) were analyzed from 1999 to 2015 by trend analysis, co-integration partial correlation analysis using MODIS-NDVI time series remote sensing data. average NDVI MRYR increased 0.72 0.80, nearly two-thirds showed a significant improvement. At inter-annual scale, relationship between meteorological factors was not most areas. inter-monthly almost significantly correlated with precipitation, relative humidity, sunshine hours, effect precipitation hours on pronounced lag. When altitude less than 2500 m, elevation. gradually as slope decreased aspect changed north south. population density per capita GDP positively afforestation policy. These findings provide new insights into effects climate change human activities growth.
