Abstract
For purpose of protecting the ecological environment of Pearl River Estuary,it is important to get knowledge of the main influence factors on the ecologic system. Firstly, an ecological model was designed in conjunction with a three-dimensional hydrodynamic and sediment model. As the model was verified to be capable to represent the distribution of ecological variables,it could be used for further research. Then,in order to find out the effect of suspended scdiment and nutrient on biological growth in Pearl River Estuary in summer, sensitive numerical experiments were carried out. The results showed that suspended sediment had limited the biological growth in the inner estuary,because the suspended sediment concentration was high in the inner estuary and light was greatly attenuated. Phosphate had limited the biological growth both in the inner and Outer estuary, and more obviously in the outer estuary.The nitrogen nutrition was abundant that it could not limit the biological growth in Pearl River Estuary. While in the inner estuary the biological growth was mainly limited by suspended sediment, and in the outer estuary it was mainly limited by phosphate, the maximum chlorophyll concentration appeared in the mouth of the estuary.关键词
