Abstract:
Flow and Sediment process controlled the formation and evolution of wetlands. They were recognized as the significant driving forces of shaping structure and function of wetland ecosystems. In this paper, the dynamic changes were studied about the area, center of gravity and wetland types of delta wetland, based on the remote sensing data of Yellow River Delta wetland area from 1976 to 2014. The results showed that constructed wetland area had increased 1000 times remarkably. However, natural wetland area had reduced 41.9% with fluctuation during the 40 years. The center of gravity reed, beach-land, culture and salt field wetlands had shifted from northwest to southeast. There were significant difference between south and north of Delta wetland evolution. Northern reed and beach-land area had a decreasing trend. While reed wetland area showed an increasing trend, beach-land area firstly increased, then decreased in southern. The research results may provide a scientific basis for the Yellow River Delta wetland ecosystem’s protection and restoration under the condition of flow and sediment variation.
