Abstract: Vegetation coverage is a major factor influencing soil and water loss and it can be obtained in a large scale more quickly and effectively through interpretation on remote sensing images. This paper briefly presents the extracting mechanism of vegetation coverage factor in remote sensing survey image of soil and water loss. Based on remote sensing and field survey data, and by taking Lanshan County of Hunan Province as experimental area, the vegetation coverage factors were extracted by integrating methods of MODIS time series data and high spatial remote sensing data; The experiment showed a positive result. The proposed method provides reliable scientific basis for the dynamic monitoring on soil and water loss in the future and has theoretical and practical significance.
