【摘要】 将闽江流域林地划分为有林地、灌木林地、疏林地和其他林地,并将有林地划分为杉木林、马尾松林、阔叶树林、竹林和经济林.利用福建省第5次森林资源连续清查固定样地资料,提取闽江流域各林地类型在闽江流域遥感图像图上的像元光谱值,分析各林地类型光谱曲线变化规律,基于遥感图像处理软件的专家分类知识库,建立闽江流域林地分类模型,对闽江流域林地利用现状进行分类.所建立模型划分出了闽江流域林地利用现状,林地分类精度总体达79%.更多还原

【Abstract】 The woodland of Minjiang River watershed was classified as forest land,shrub land,open woodland and other woodland and the forest land was classified as land of Chinese fir,land of Pinus massoniana,land of broadleaf,land of bamboo and land of commercial forest in this paper.The model of Minjiang River woodland expert classification was established by analyzing the rule of the spectral curve which was exeracted from the TM images with the help of the fifth forest resource continuous investigation data in the Minjiang River watershed.The woodland of Minjiang River watershed was classified through the model and the total precision of the result was 79%.更多还原
