This paper discusses knowledge discovery and feature extraction on the basis of traditional classification method of the remote sensing picture. Multi-level classification method is used in monitoring of mining area land cover. This method is superior to the classifying device of single routine. In this paper, Kailuan mining area land cover change is obtained by using multi-level classification method dealing with Kailuan mining area remote sensing images.
This paper discusses some key issues in the ecological reclamation. First, terrain, water system, the soil physical and chemical properties, and biological changes in the mining subsidence area were monitored; the ecological environment and soil ecological destruction mechanism and farmland ecological system elements space-time evolution rules in mining subsidence area were revealed. Second, the landscape pattern changes before and after reclamation were examined with RS and GIS technology. Finally, the mining subsidence area landscape ecology remodeling technologies were carried out.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
