Climate drivers The seasonal WYM and decadal NP had significant positive contributions to the vegetation coverage over the whole Gansu, especially the southeast region. Despite not statistically significant, the interannual CP negatively contributed to the vegetation variation over the most part of the Gansu, especially the northwest region, but positively to the southeast region. The vegetation coverage is mainly concentrated in the southeast Gansu, which is positively affected by three climate factors.
