Abstract

Based on the TM remote sensing images obtained in Guyuan County of Hebei Province in 1998, 2003 and 2008

and the landuse map as well as field data of the study area , the authors analyzed the spatial and temporal

patterns for dynamics changes of the vegetation cover in Guoyuan County in the past ten years by using the

dimidiate pixel model and expert classifier and consulting the statistical data with the purpose of understanding

the situation of ecological control The results show that most areas were in the moderate and relatively high cover

in the three monitoring periods, with the vegetation cover being improved in general. The condition of vegetation

cover was stable between 1998 and 2003, and was improved between 2003 and 2008. The areas with slightly increased

vegetation cover was mainly distributed in the plateau farmingpasture area, and the stable areas were mainly

distributed in the southern low mountain areas. The effect of the regulation project is remarkable.
