| 摘 要： | 农牧交错地带地类复杂,混合像元现象严重,湿地信息的自动提取难度较大.针对该区湿地遥感信息提取的特点和难点,选取多伦县大仓乡地区的TM遥感数据,先采用NDVI阈值提取出水体,并利用水体形状特征(如面积s、周长p、形状指数k等)对水体类型进行提取;再尝试应用线性光谱混合模型( LSMM)提取去除水体后的湿地信息,并以SPO...

| Abstract: | In the farming-pastoral area,the land types are complex and the mixed pixel phenomenon is serious,so the automatic extraction of wetland information is difficult.In view of the characteristics and difficulties of wetland remote sensing information extraction in these regions,the authors selected the TM remote sensing data covering Dacangxiang area in Duolun County to study a new method of wetland automatic extraction.Firstly,the NDVI threshold method was used to extract water body and then water types were ... |
