The vegetation coverage in the Zoige Region based on a pixel binary model was estimated in this study using the MODIS-NDVI data,vegetation map,soil map,and meteorological data.Then,the spatial pattern and variation rules of vegetation coverage from 2000to 2015,as well as the response of vegetation coverage to climatic factors were analyzed with a trend line,correlation analysis,and lag analysis.The results showed that 1)The mean vegetation coverage in the Zoige Region fluctuated between 77%and 82%in 16recent years,with a ratio increasing by 1.4%per 10years.Among the 7types of vegetation,the coverage of the broad-leaved forest(87%)was the highest,and the alpine vegetation(44%)was the lowest;the grassland vegetation exhibited a slight downward trend with a ratio of-0.2%per 10years.2)The vegetation coverage in the Zoige Region showed that the distribution features were high in the east and low in the west,decreasing from the center to the periphery,and the mean annual vegetation coverage change rate was between-0.053~0.027.In this region,the main vegetation coverage types were high and higher levels of vegetation coverage with a rate of 84.32%,and the two areas had a tendency of mutual transformation.3)The lag analysis showed that the vegetation coverage in the growing season exhibited a good correlation with the contemporaneous air temperature, but the response to accumulated precipitation was evidently delayed for approximately 1month.4)At the significance at the 0.05level,the area change of vegetation coverage affected by climatic factors was 7.58%,of which the air temperature drivers accounted for 2.85%,the accumulated precipitation driver accounted for 2.17%,and the air temperature and accumulated precipitation were weak drivers accounting for 1.67%.Furthermore, most areas were affected by non-air temperature and accumulated precipitation factors.
