由于红树林所处的地理环境,利用传统方法对其进行实地调查是很困难的。。感技术的发展为红树林湿地研究提供了新的方法和强有力的技术支持。该文以landsat TM影像为基础对广西沿海地区红树林进行识别,分别应用最大似然法和决策树法,发现基于缨帽变换的决策树方法精度更高,能准确的提取出红树林信息。
由于紅樹林所處的地理環境,利用傳統方法對其進行實地調查是很睏難的。。感技術的髮展為紅樹林濕地研究提供瞭新的方法和彊有力的技術支持。該文以landsat TM影像為基礎對廣西沿海地區紅樹林進行識彆,分彆應用最大似然法和決策樹法,髮現基于纓帽變換的決策樹方法精度更高,能準確的提取齣紅樹林信息。

Because of the geographical conditions under which mangrove lived,it was difficult to undertake field investigations by traditional methods.The development of remote sensing technology provided a new method and powerful technical support to the research mangrove wetland.Based on landsat TM image,mangrove forest in the coastal area of Guangxi were identified by applying NDVI and tasseled cap transformation method.The results showed that the decision tree method based on tasseled cap transformation had higher accuracy.The information of mangroves could be accuratelyextracted.
