| 摘 要： | 湿地是水陆交界处,水位对于洞庭湖湿地的变化有着显著的影响。针对洞庭湖湿地涨水为湖、落水为洲的典型特点,选取同一年水位变化最大的2个时期影像。针对TM影像数据量大、冗余的特点,在实践中利用地图光谱特征及最佳指数、联合信息熵等指数来考虑最佳波段的组合,选取出最佳的包含2个季相特征的波段组合,可取得较好的效果。

| Abstract: | Wetlands is the junction of water and land.The water level of Dongting Lake have a significant impact to the wetland change.Considering the characteristics of rose water as lake,fell as continent,two TM images of the water level maximum changes in the same year were selected.Considering the characteristics of data volume and redundant features,the map spectral features、the best index and the information entropy index were used in practice to consider the best combination of bands,the best band combination with two quarter-phase characteristics were selected,which could achieve fairly well results. |
