Changes of Grassland Rain use efficiency and NDVI in Northwestern China from 1982 to 2013 and its response to climate change
The grasslands in arid and semi-arid regions rely heavily on the use of rain, thus, improving rain use efficiency (RUE) is essential for securing sustainable development of grassland ecosystems in these areas with limited rainfall. In this study, the spatial and temporal variabilities of RUE for grassland ecosystems over Northwestern China during 1982-2013 were analyzed using the normalized differ
