Abstract:: Using MODIS NDVI of 8 years to build time series data sets and analyze the vegetation coverage temporal pattern and evolution of Yanhe Basin from 2003 to 2010. Using spatio-temporal data model and the grid pixel as units, and calculating GRC from 2003 to 2010, the vegetation coverage about 2003 and 2010 was inverted. The results showed that: (1) the vegetation growth tended to be improved in Yanhe watershed, vegetation coverage of southern Yan’an region and southeast of Baota District and county in the central extension of was better and more stable; (2) vegetation was significantly restored in South Ansai County, Yanchang County and the major part of Wangyao reservoir in middle area of Xingzihe; (3) vegetation presented the degradation trend in urban and urban key development areas. The local vegetation degradation was mainly caused by the unreasonable land use and the vegetation destruction caused by the urban development. Pixel-based analysis is more easy to reflect the spatial and temporal evolution of regional NDVI details.
