Based on the analysis of estimation methods for vegetation coverage at home and abroad

a technological route of model application is designed to estimate vegetation coverage in the upper reaches of Huaihe River.The study is conducted by using binary pixel model and "Beijing-1" micro-satellite multi-spectral data under consideration of the situation of the study area.Then the estimated results are validated and analyzed by using ocular method and photographic method.Results show that the model correlation coefficient is 0.818.The average vegetation coverage in the study area is 58.1% and presents a γ-type spatial distribution which is low in the north and high in the south.
