Vegetation Cover Change on Hulun Buir Grassland

Abstract

Abstract: A time series of GIMMS-NDVI data from 1982 to 2006 were used to monitor the vegetation cover change on Hulun Buir Grassland.The result showed that the growing season was significantly prolonged,which was mainly impacted by the early greenup date with increasing temperature in spring,and the wilting date had little effect.The trend of vegetation dynamic change decreased slightly,but not significantly,and mainly interannually from 1982 to 2006.The early greenup date contributed little to the total grass biomass.The vegetation in eastern region was greatly improved but degradated in the western region,and the sandy vegetation was degradated on the whole,especially in the southern region.Moreover,the local moving dunes became more active.

Key words: vegetation cover, NDVI, phenology, trend, Hulun Buir
