摘要: 基于地物光谱特征,采用光谱角分类技术将主要地物覆被类型进行了分离,并依据经验知识构建了各用地类型的专题信息模型,提取了安徽省土地利用信息,通过分析2000、2005和2010年3期遥感调查结果,得到了安徽省土地利用动态变化及不同土地利用类型之间的转换情况。结果表明:安徽省的土地利用面积以耕地和林地为主,近10年来林地面积持续增加,而建设用地扩建现象严重,导致耕地被大量占用。

Abstract: The spectral features of each land use type was analyzed, and the spectral angle mapper was used to separate the main cover types, and the thematic information models of each land use type were constructed based on experience and knowledge. Remote sensing information extraction technology based on the knowledge wasused on the land use information extraction in Anhui province. Land use information of Anhui province was extracted automatically using a computer. By analyzing the three remote sensing survey results of the year of 2000, 2005 and 2010, the information of the land use dynamic changes and conversions between different land use types was obtained. The results showed that the farmland and forest land were the main land use types in Anhui province, and the forest area continued to increase, but the farmland area decreased because of the construction land expansion.
