Abstract

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.
