The research carried out an experiment of extracting water from inland limnetic wetlands using TM remote sensing imagery based on many arithmetic,and concluded that spectrum classification was the best among the area accuracy index,extraction accuracy index and visual effect index,the following was single band threshold and vegetation index method,however,multi-band relationship and water index method was the worst.

研究基于TM遥感影像，运用多种方法针对典型内陆淡水湿地的水体信息进行了提取实验，通过对实验结果的分析得出：在面积的准确性、提取的准确度以及视觉效果3种指标下，光谱分类法较其它方法效果要好，其次为单波段阈值分析法与植被指数法，较差的是多波段谱间关系法与水体指数法；影响提取效果的主要原因是湿地水体提取不够完全，这是由影像的分辨率及湿地特殊的水文条件所造成的，采用像元分解及多源遥感数据融合技术将成为提高水体提取精度的重要手段。
