Abstract

Abstract: Taking the Beiluo river basin as an example， the Landsat TM image data in 1995， 2007 and 2014 were employed and the vegetation coverage was derived to analyze how the vegetation restored.The results showed that the average vegetation coverage in the three years of the whole basin are 46.43%， 63.42%， and 73.4%， respectively. The trends of vegetation distribution on landform were analyzed in the upper reaches of the basin. It is showed that whatever the elevation belts， slope gradient spans， and slope aspect zones were， the vegetation coverage improved distinctively in 1995， 2007 and 2014. Meanwhile， the extent or the area of low vegetation coverage transforming to high vegetation coverage tends to be greater with the elevation lower， slope gradient larger， and slope aspect inclining to be shady.

Key words: vegetation restoration, vegetation coverage, landform factors, Beiluo river, loess hilly gully region
