Abstract: The heterogeneity and fragmentation of land were serious and the spectrum was complicated in northern farming-pastoral regions,so the land use and cover classification research was highly dependent on visual interpretation. Duolun County was selected as a test area and the knowledge-based remote sensing information-extracting technology was applied to this area. The main cover types were decomposed by linear spectral mixture model. And a number of thematic information models were set up by the analysis of spectrum. The extraction rules of all cover types were set up based on empirical knowledge,and then the land use information of Duolun was extracted automatically on a computer. The results showed that the area precision by this method was 93.8% and the sampling point precision was 87.7%. The corresponding results of supervised classification were 71.1% and 59.5%t. It was proved that the method was more effective than supervised classification and could realize the fast extraction of remote sensing information with high precision and multiple tiers.[Ch,4 fig. 3 tab. 20 ref.]
