Research on Hydrodynamic Driving Mechanism and Improvement Plan for Ecological Restoration in Binzhou Sea Area
摘要
Abstract
In order to restore the coastal ecology system,some means are often used to enhance the hydrodynamic conditions of wetlands,for instance,opening up water exchange channel.Water exchange efficiency,water level and vegetation restoration are affected by the width of the water exchange channel and tidal fluctuation.Therefore,appropriate width of water body exchange channel,water body exchange capacity and change in water level have fundamental significance for the coastal ecology restoration.By now,a few researches have been done for the adaptability of hydrodynamic conditions to the vegetation restoration.Based on the ecology restoration project ranging from Toure River estuary to Shunjiang trench in Binzhou sea area,by establishing hydrodynamic models and convection diffusion models,research and analyse were carried out for the relationship between local hydrodynamics and water exchange subject to different opening-up widths,complete with the recommended values for the width of water exchange channel and the water level of ecology restoration.The results shows that the water exchange efficiency basically reaches 90%or more after 20 days.When the field elevation is 0.79 m,the average daily water filling duration is 2.1～2.6 h,which meets the water level requirements of planting sea-blite.关键词
