With the rapid development of digital graphic recognition technology, in recent years, more attention is given to the subject of animal and plant species identification which has become a popular researching field. The article mainly discusses about the method to apply graphic analyzing technology for bird identification research in the case of aquatic bird protection in the marsh of Nine Turns Stream. It also put forward a set of classification case with SVM Decision Tree for protesting information through deep analysis and study on bird color graph in terms of shape, color and texture. Moreover, the appearance of the case contributes to the effective recognition and classification of birds in species Nine Turns Stream wetland,and then provides the scientific basis for bird biodiversity research and conservation.
