Shifts in vegetation growth in response to multiple factors on the Mongolian Plateau from 1982 to 2011

摘要: Abstract The Mongolian Plateau (MP) steppe is one of the largest environments in world. To monitor terrestrial vegetation dynamics on MP and to ascertain what driving forces, this study examined Republic Mongolia (M) Inner Autonomous Region (IM) China from period 1982 2011, based satellite-derived GIMMS NDVI3g (Normalized Difference Vegetation Index) data across three biomes (desert, grassland forest). results are as followed: (1) coverage IM was generally greater than that M. Before 2002, time series NDVI over increased at an average rate 0.05% yr −1 . Additionally, after a 0.21% yr From area M with positive anomalies separate 1.82% yr 1.76% yr , respectively. (2) At biome scale, inter-annual forest variation desert for entire had significant increasing trend (0.06% yr 0.04% yr respectively). (3) Climate forcing dominant controlling factor affecting vegetation, anthropogenic behavior exhibited no value whole region. However, overgrazing most important reason regional degradation, particularly IM. (4) In future, will go recovery, whereas both predicted degrade continuously.
