中文摘要：

一条海岸线被定义为平均春天潮线。海岸的不同类型例如沙、淤泥、生物的海岸，有解释的不同指示物。为解释所有海岸线开发一个通用方法是很困难的。因此，沙，淤泥，并且当研究反对，生物海岸被考虑，并且与数据采矿技术，发现海岸线的那些三种类型的解释的规则。然后，一个聪明的海岸线解释方法基于规则被建议。第一，在 Landsat TM/ETM+ 提取吃水线的规则(题目的 Mapper/Enhanced 题目的 Mapper 加) 形象被发现。通过分析沙、淤泥、生物的海岸的特征，当时，解释海岸线的不同类型的指示物是坚定的。根据指示物，吃水线能被改正到真实海岸线。以便验证建议算法的有效性，三 Landsat TM/ETM+ 形象为案例研究被选择。试验性的结果证明建议方法能与高精确并且没有人的干预解释沙、淤泥、生物的海岸的海岸线，它超过了三个象素。

英文摘要：

A coastline is defined as the average spring tide line. Different types of seacoast, such as sandy, silty, and bio- logical coast, have different indicators of interpretation. It is very difficult to develop a universal method for interpreting all shorelines. Therefore, the sandy, the silty, and the biological coast are regarded as research objects, and with data mining technolog,found the rules of interpretation of those three types of coastlines. Then, an intelligent coastline interpretation method based on rules was proposed. Firstly, the rules for ex- tracting the waterline in Landsat TM/ETM＋ （Thematic Mapper/Enhanced Thematic Mapper Plus） imagery were discovered. Then, through analyzing the features of sandy, silty and biological coast, the indicators of interpreting different types of shoreline were determined. According to the indicators, the waterline could be corrected to the real coastline. In order to verify the validity of the proposed algorithms, three Landsat TM/ETM＋ imageries were selected for case studies. The experimental results showed that the proposed methods could interpret the coastlines of sandy; silty, and biological coasts with high precision and without human intervention, which exceeded three pixels.
