abstract = "{Previous studies have concluded that the increase in vegetation in the
arid northwest of China is related to precipitation rather than
temperature. However, these studies neglected the effects of
climate warming on water availability that arise through changes
in the melting characteristics of this snowy and glaciated
region. Here, we characterized vegetation changes using the
newly improved third-generation Global Inventory Modeling and
Mapping Studies Normalized Difference Vegetation Index (GIMMS-3g
NDVI) from 1982 to 2011. We analyzed the temperature and
precipitation trends based on data from 51 meteorological
stations across Northwest China and investigated changes in the
glaciers using Gravity Recovery and Climate Experiment (GRACE)
data. Our results indicated an increasing trend in vegetation
greenness in Northwest China, and this increasing trend was
mostly associated with increasing winter precipitation and
summer temperature. We found that the mean annual temperature
increased at a rate of 0.04 {\textdegree}C per year over the
past 30 years, which induced rapid glacial melting. The total
water storage measured by GRACE decreased by up to 8 mm
yr$^{-1}$ and primarily corresponded to the disappearance of
glaciers. Considering the absence of any observed increase in
precipitation in the growing season, the vegetation growth may
have benefited from the melting of glaciers in high-elevation
mountains (i.e., the Tianshan Mountains). Multiple regression
analysis showed that temperature was positively correlated with
NDVI and that gravity was negatively correlated with NDVI;
together, these variables explained 84\% of the NDVI variation.
Our findings suggest that both winter precipitation and warming-
induced glacial melting increased water availability to the arid
vegetation in this region, resulting in enhanced greenness.}",
