Abstract: 【Objective】 To validate the applicability of remote sensing monitoring of inedible grass Pedicularis sp. by GF-1 WFV (16m) satellite and understand the inedible grass Pedicularis's distribution of the study area in Bayanbulak grassland.【Method】The corrected GF-1 WFV remote sensing satellite images were combined with the measured spectral data. The method of visual interpretation was applied combined with supervised classification of the inedible grass Pedicularis sp. identification to verify its classification accuracy. And then the accuracy of classification and distribution of Pedicularis sp. were discussed.【Result】The result of accuracy evaluation indicated that the overall accuracy was 80.91%, and the Kappa Coefficient was 0.71. The classification result was better. Thus the distribution range of the poisonous grass Pedicularis sp. in Bayanbulak grassland and the main reasons affecting the classification accuracy were obtained.【Conclusion】The result showed that the applicability of remote sensing monitoring of inedible grass Pedicularis sp. by GF-1 WFV (16 m) satellite in Bayanbulak grassland was feasible. The classification results of the study area of remote sensing interpretation and field survey found that the damaged area of grass Pedicularis sp. area is rather large, and most of them are contiguous and distributed along the river. The seriously damaged areas were Bayanbulak parvial field of the Bayanbulak total field, Hal Sara village of Bayingolin Township, the Gabriele Basilico village of Bayanbulak Town.
