Abstract:

Vegetation,as the first producer,plays an important role in the energy transformation and material cycle of the ecosystem.Using GIMMS NDVI3g dataset,spatial distribution,trend,and sustainability of vegetation fractional cover in Hebei were analyzed by trend analysis and Hurst methods.The result shows that the average vegetation fraction cover within growing season from 1982 to 2015 is 49.4%.The vegetation fraction cover shows an increasing trend with a linear slope of 1.5%/10a from 1982 to 2015.The area with increased vegetation fractional cover occupies more than 90% of the total land.Results of Hurst analyses indicated the regional vegetation cover will increase in sustainability in the future.The coupling of slope and hurst analysis shows the index of hurst in the increased and decreased area is 0.86 and 0.85,which indicates the trend will persist in future years.

Key words: NDVI, GIMMS NDVI3g, Beijing-Tianjin-Hebei, vegetation fractional cover, sustainability
