The annual dynamics and spatial variability of vegetation in northwest Guangxi were studied based on the SPOT NDVI datasets during 1999-2010. The response of vegetation to climate and topography was analyzed. The results showed that: (1) Vegetation had a large proportion of increasing trends in northwest Guangxi from 1999 to 2010. Partial correlation analysis between NDVI and climate parameters showed that climate had little effect on vegetation. ( 2) Elevation affected vegetation trend. It increased between 200 and 500 m, however, there were a small areas between 400 m and 500 m where vegetation decreased. Vegetation tended to be stable as the elevation increasing. ( 3) Vegetation recuperated on slopes between 6毅and 15毅, but decreased on slopes between 2毅and 6毅 and above 25毅. (4) The differences of vegetation restoration on aspects were not obvious. However, vegetation recovery trended to be decreasing as the aspect turning from shady to
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
