Abstract
Using remote sensing data and ground meteorological station data, we estimated NPP of vegetation during the growing season from 2000 to 2013 in Horqin sandy land under the support of remote sensing and GIS Technology. We analyzed the relations between the annual NPP with climate factors and human activities. The results showed that the vegetation NPP was increased fluctuations during growing season in Horqin sandy land from 2000 to 2013, the average increase rate is 6.338/a. And the fluctuation is bigger, increased from 291.32gC/m2/yr in 2000 to 431.75gC/m2/yr in2013. In spatial pattern, overall showing a decreasing trend from southeast to Northwest, and the area of high NPP increased while that of low NPP decreased., the NPP in southern fringe regions of the study area showed increasing trend, and eastern, western and northern fringe regions of the study area showed reducing trend or no obvious trends were observed.. Climate features and human activities were the main causes inducing the increase of vegetation NPP, and precipitation was the dominant driving force of NPP of Horqin sandy land.
