Abstract

Abstract:

Aims Vegetation distributions are determined by diverse environmental conditions at different spatial scales. Our aim is to analyze the relationship between environmental factors and vegetation cover at different spatial scales.
Methods We obtained the distribution of NDVI in the Ordos Basin by mapping the remote sensing data (landsat5 TM). Using GIS software, we built a geo-database in the form of a thematic map and carried out spatial analysis to detect the relationship between the environment factors and NDVI at different spatial scales.
Important findings At the scale of the Ordos region, mean annual rainfall plays an important role in vegetation distribution and high-cover vegetation mainly occurs in geomorphology regions of diluvial and alluvial deposits. At the scale of the Kubuqi Desert, geohydrologic condition is one of the important factors contributing to the distribution of vegetation cover. In Mu-Us, the lithology of sublayer terrain greatly affects vegetation cover and distribution.

Key words: Ordos, Mu-Us, NDVI, vegetation distribution, vegetation cover
