Erdos Larus Relictus Nature Reserve is the only wetland of international importance to protect Larus Relictus in China. From the early part of this century, the impact of water use, vegetation construction and the climate of the catchment area increasing on the wetland of this Nature Reserve has brought about severe water shortage. Until now, no eco-hydrological model at home or abroad integrates the wetland ecological and hydrological processes. This paper considers the relationship between the food chains of the Larus Relictus and environmental elements, and establishes the eco-hydrological processes from Larus Relictus to damselfly + Chironomidae and the salinity and the area of Bojiang Lake. It also establishes a relationship among Larus Relictus breeding, the area of islands outcropped in the levels of the lake and hydrological season based on the relationship between Larus Relictus breeding and environmental elements. The eco-hydrological model is then constructed according to these relationships. In virtue of the constraints of the lake salinity, the suitable area of the lake is 9.01 km2, and 4.88 km2 for the smallest area. While in accordance with the area of islands outcropped needed for Larus Relictus breeding, the lake area is 11.02 km2 in breeding season corresponding to critical high level.
