摘　　要：以2003年4月16日的TM\ETM数据为数据源,采用最大似然法提取了湖北麻城市境内杜鹃分布信息,分析了麻城杜鹃在不同海拔、不同坡度、不同坡向的分布特征,结果表明:麻城市的野生杜鹃主要分布于海拔600~900 m的范围内,海拔越高,杜鹃的覆盖率越大,是海拔900 m以上山地的优势物种,60%以上的杜鹃分布在坡度15~35°的范围内,南坡分布的比例多于北坡,表明本地杜鹃趋向于分布在高海拔、陡坡度的南坡。Based on TM / ETM data of April 16, 2003, the maximum likelihood method was used to extract the distribution information of Azalea in Macheng City, Hubei Province. The distribution characteristics of Rhododendron at different altitude, slope and aspect were analyzed. The results showed that the wild Rhododendron was mainly distributed in the range of 600 to 900 meters above sea level. The higher the altitude, the higher the coverage of the Azalea,and it was the dominant species above 900 meters above sea level, more than 60% of the Rhododendron was in slope 15- 35°,the proportion of the southern slope is more than that of the northern slope, indicating that the local Rhododendron tends to high altitude, more steep south slope of the mountains.
