Sanjiang Plain was chosen as the study area in this paper, based on the relationship between species and their habitats, using principles of landscape ecology and protection biology, "3S" technique, same surface areas of hexagons as forecasting and evaluating units to analyze protection status of state protection wetlands birds and diversity of their habitats, to find the unprotected biodiversity hotspots there and then analyze the priority protection. The study results showed that nationally protected bird categories I, such as Ciconia boyciana and Haliaeetus albicilla have been protected well, the area which protects in the protected occupies its distribution area 41.5% and 31.2%, simply has obtained the very good protection. The Mergus squamatus, Grus japonensis and Aquila chrysaetos also occupy their always dispersal area in the protectorate dispersal area above 20%, but their main distribution area not in protectorate, mainly is nature or half natural ecosystem. Some birds under second class state protection as Bubo bubo, Falco peregrinus, Accipiter gentilis, Falco tinnunculu, and Strix uralensis have not been well protected. Specially Bubo bubo, only protects its dispersal area 0.6%, simply h as not obtained the very good protection. Looked from various ecosystem type that, the typical meadow and the island forest to protect well, but the islands, the Reed marshesand the rivers ecosystem to protect relatively bad. Thirteen hotspots have been discovered in this area, which are mainly distributed in surroundings near nature reserve and coast of some great rivers.
