DISCUSSIONS ON ECOLOGICAL EMBANKMENT OF WET-DRY ZONE - STUDIES ON THE ECOLOGICAL EMBANKMENT OF LAKE LONGEVITY WET-DRY ZONE
Wet-dry zone is an area that the flooded land exposed on the water surface periodically with the seasonal water fluctuations in reservoirs. It is a unique phenomenon of reservoir. This article aims to demonstrate and develop the ecological embankment by incorporating ecological elements when designing the wet-dry zone embankment. Take the embankment design of Lake Longevity wet-dry zone as an example, different shore status of fluctuating conditions were analyzed. There were 4 types of embankments: the lawn-type, the rocky beach-type, the stone-type, and the muddy-type. The natural prototype, the nature-type and the artificial-natural type of eco- embankment were carried out by introducing the concept of eco-embankment design according to each different water level conditions. On the basis of ecological priority and people-oriented design principles, the embankment construction mode was soil and water conservation + buffer zone + ecological revetment + lake, which combined with the cultivation of aquatic plants. The essay has come to the conclusion that the construction of wet-dry zone embankment should be satisfy the demand of both man and nature and establish a balanced and dynamic system through the exchange between land and water in accordance with different water levels.
