| Abstract: | The paper took Minjiang watershed as research object based on RS with the aid of ERDAS,ArcGIS,EXCEL and so on.It choosed the vegetation index method,according to the the dimidiate pixel principle,builded the model of vegetation coverage estimated by the vegetation index of VBIS,produced the vegetation coverage graduation map of Minjiang watershed,and made the analysis and appraisal to the change of its structure,showed the law of spatial change in the vegetation coverage of Minjiang watershed. |
