Paper Abstract

With the technological development background of "3S", the research area is Yachi demonstrate area in Bijie city of Guizhou. For traditional methods, NDVI is always used to extract Vegetation information from remote sensing image. Based on theory of dimidiate pixel model,the study region defined NDVISsoil and NDVISveg,vegetation, the inversion dimidiate pixel model was established based on vegetation index(NDVI) to extract vegetation coverage, vegetation coverage can be calculated by using the model of quantifying vegetation fraction from normalized difference vegetation,then acquired relationships between NDVI Serial Images and landscape pattern karst rock-desertification, finally yachi demonstrate area gainer karst rocky desertification landscape pattern of distribution. Using this methods of karst rocky desertification landscape pattern research has significantly improved the accuracy of classification, providing a scientific basis to ecological restoration of karst rocky desertification and other integrated control.
