从遥感图像看口门规划治理效果--珠江口伶仃洋和东四口门治理的遥感分析

利用遥感技术来观察伶仃洋，可以在是获得大面积的地表或地表浅层信息，其时间上的同步或准同步性克服了以前由直接观测点或线推证到面的局限性，为伶仃洋和珠江三角洲东四口门规划作局部工程治理监测提供了准确可靠的数据资料。通过遥感技术获得的技术图片和数据，分析伶仃洋两槽三滩动力一地形结构，复杂的径流、潮流、沿流动力机制及其泥沙主要来源，提出东西部动力区具有相对分界线的新观点，并论证大喇叭和小喇叭规划治理方案；

Results of Outlet Improvement Viewed from Remote Sensing Photos

Synchronous and quasi-synchronous information acquired in a larg area in a moment by remote sensing technique has notonly overcome the limitations of data obtained by observations uesd to be done before, but also provided accurate and reliable data forthe planning and improvement of Lingdingyang Bay and four eastern outlets. According to the photos and data obtained by remotesensing technique, having analizind the dynamic topographic structure, complicated dynamic mechanism of runoff,tidal current andcoast current and major sediment sources in Lingdingyang Bay, the authors put forward a new standpoint that there exists a reativedemarcration line in the easern and wesern dynamic zones and compare the big bell mouth scheme with the small bell mouth schame.They also make an evaluation to the improvement and reclamation projects at Jiaomen Outlet,Jibaosha Shoal, Hongimen Outlet and Hengmen Outlet.
