中文摘要：

针对全国海域使用情况的监测需求,本文应用扩展的证据理论进行围填海区域检测,预设类别空间为{围填海,海水}。实验结果显示基于扩展的证据理论不仅能够较准确地检测出围填海区域,而且将浅海中的水下沙脊或小岛划分为不确定的未知类别。说明扩展的证据理论能够更好地完成围填海的检测,体现了扩展的证据理论解决实际问题的能力,同时,也为全海域的围填海监测提供了新的思路和扩展空间。

英文摘要：

Aiming at the monitoring requirement of sea area using situation,the extended evidence theory is used to detect reclamation area and the default category space is {reclamation,seawater}.Experimental results show that the extended evidence theory can not only detect the reclamation area with high accuracy,but also identify the underwater sand ridges or small islands in the shallow water as the uncertainty category.That shows the extended evidence theory has the ability to solve the problem of reclamation detection,which provides a new thinking of reclamation monitoring.
