摘要
以博鳌亚洲论坛为契机迅速发展的位于万泉河河口地区的海南博鳌旅游度假区 ,在海内外享有较高的知名度和旅游吸引力。旅游度假区内地貌景观的多样性特征显著 ,集丘陵山地、海洋、泻湖洼地、岛屿、河道、沙坝、河口海岸等地貌景观为一体 ,万泉河河口地区长期以来保持优美的自然景观 ,具有很好的旅游开发前景。博鳌旅游度假区以泻湖—沙坝、河口岛屿—潮汐汊道为主的沉积地貌体系 ,发育于全新世海平面上升的背景下 ,现代地貌格局约在 3 0 0 0aBP形成。河口海岸和江心洲地貌稳定性问题成为海南岛博鳌旅游度假区可持续发展的关键影响因素 ,其中口门附近的稳定性最差 ,玉带滩北段的海岸侵蚀比较明显 ,万泉河主河道南岸的侵蚀比较严重 ,沙美内海的淤积则不断加强。结合区域地貌特征 。
Boao,the rapidly developing tourist resort with strong attraction,is now famous at home and abroad for the Boao Asian Forum.The landscape in the tourist resort is characterized by the diversity of landforms such as hill,sea,lagoon,island,river channels,and sandbar in the esturay of the Wanquan River.The whole landscape is in the perfect natural condition for a long time with the best perspectives for the touring development in the future.The sedimentary morphological system in Boao tourist resort is mainly composed of lagoon-barrier and island-tidal channel,which were formed in 3 000 aBP.The morphological stability is the key factor affecting the sustainable development of tourism in the Boao tourist resort.The river mouth is in the worst condition of instability.The northern Yudai barrier is experiencing the strong coastal erosion.The southern bank of the tidal channel is eroded by the river especially by the floods.The sedimentation in Shanmeineihai lagoon is intensified.Based on the actual morphological characters,some countermeasures have been put forward for the solution to the slope instability problem.
