盘锦红海滩国家风景廊道海域潮沟规划研究

Study on tidal gully planning of Panjin Red Beach national scenic corridor

受自然环境变化和人类活动影响,辽河口湿地面积衰减、翅碱蓬植被退化、红海滩面积萎缩等问题突显。本文根据潮滩潮沟发育现状,分析潮水流动阻碍因素,提出人工规划潮沟方案。通过选定控制方程组和边界条件,采用平面二维自由表面流模型对潮沟规划后的海域进行水动力学验证,对人工潮沟方案进行调整,最终得出较为合理的海域潮沟规划方案。本研究结果为相似条件下海域潮滩潮沟规划提供了技术参考。

Influenced by the changes of natural environment and human activities,the problems of wetland area attenuation,Suaeda heteroptera vegetation degradation,and red beach area shrinkage in Liaohe River estuary are prominent.According to the development status of tidal flats and gullies,this paper analyzes the hindering factors of tidal flow,and puts forward the scheme of artificial planning of tidal gullies.By selecting the governing equations and boundary conditions,the plane two-dimensional free surface flow model is used to verify the hydrodynamics of the sea area after the tidal ditch planning,and the artificial tidal ditch scheme is adjusted,and finally a more reasonable tidal ditch planning scheme in the sea area is obtained.This study results can provide technical reference for tidal flat and gully planning in similar conditions.
