遥感在海岸岸滩稳定性分析中的应用

Study of coastal stability in the Sanmen Bay based on the remote sensing data

利用多时相航卫片图像信息和现场观测资料相结合的研究方法，通过对三门湾自然环境、水动力条件、泥沙运动等因素分析，研究海岸岸滩形态及演变过程，指出该地区的岸滩稳定性现状和影响因素．提出利用航卫片技术有空间分布和环境动态分析方面的优势，结合常规水文地形资料进行海岸岸滩稳定性综合分析的新思路．

An approach combining field data with remote sensing data to study the coastal stability is developed. Problems, such as tide field, sediment movement and distribution and tideland for cultivation are discussed. The results demonstrate that the shore and the beach of the Sanmen Bay are basically steady under the condition of limited cultivation.
