dc.description.abstractThe Poyang Lake Hydraulic Project (PLHP) has been proposed to address the water resource shortage and hydro-environment deterioration in Poyang Lake. This proposal has raised concerns over the possible changes to the habitat of aquatic organisms. Vallisneria natans is a main food source for the Siberian Crane, an indicator species for migratory birds in Poyang Lake. In this study, the influence of the PLHP on the habitat suitability of Vallisneria natans is predicted based on a hydrodynamic model and the growth characteristics of Vallisneria natans. The results show that the effect of the PLHP varies greatly in different typical years. The mean monthly habitat area of Vallisneria natans can increase by up to 191% in a low-water-level year, 145% in a medium-water-level year, yet only 18% in a high-water-level year. The habitat area can reach more than 1000 km2 during most of September and October, nearly 1/3 of the total area of the lake region. It indicates that Vallisneria natans will gain large areas of land suitable for its growth, and provide abundant food sources for Siberian Crane during winter. These findings can be helpful to evaluate the ecological benefits of the regulatory schemes of the PLHP.
