遥感技术在三亚海岸带地质环境调查中的应用

Application of Remote Sensing Technology in Geological Environment Investigation of Sanya Coastal Area

为了研究三亚海岸带地质环境状况,本文通过遥感技术,采用1987年的TM、2000年的TM、2010年的Rapideye和2015年的QB2四个时相的卫星遥感数据,对比研究过去28年来三亚海岸带地质环境变化情况,利用平衡岬湾模型软件Mepbay对工程用海海岸进行静态平衡岸线模拟,在研究中发现三亚海岸带地质环境有较大变化,地质灾害点较多,岸线侵蚀、淤积问题突出,岸线变迁幅度较大,造成三亚海岸带地质环境变化的主要原因是人们过度开发海岸带资源,用海工程规划设计不合理,缺乏环境保护意识,其次是自然因素。

In order to study the geological environment of Sanya coastal area,through remote sensing technology,namely,the satellite remote sensing data of TM in 1987,TM in 2000,Rapideye in 2010 and QB2 in 2015,this paper compared and studied the geological environment changes in Sanya coastal area over the past 28 years,and carried out static equilibrium shoreline simulation of engineering coastal area by using equilibrium headland-bay model software Mepbay. The research found that the geologic environment of Sanya coastal area has undergone a great change,besides,there are many geological disaster points,the shoreline erosion and siltation problems are prominent,and the coastline changed a lot. The main reason for the changes of the geological environment of Sanya coastal area falls to human,such as over-development of coastal resources and environment,unreasonable planning and design of maritime projects,the lack of awareness of environmental protection,followed by natural factors.
