The Remote Sensing Investigation of Eco-environmental Status in Western China
中国西部地区生态环境现状遥感调查

Aiming at the demand of Remote Sensing Investigation on Eco environment in Western China,this article synthetically utilizes the theory of Scenical Ecology,the theory of the service function of ecological system,the theory of the sustainable development and the technology of RS and GIS to study the process and integration of the RS data about eco environmental status in Western China.Based on that,the research staff develop the complex research about the constructional change of the landcover and eco elements in Western China,about the evaluation of the intensity of the desertification and water erosion,about the analysis of the ecological frail characteristic and temporal and spatial distribution law,about the evaluation of the eco environmental quality based on RS investigation and about the analysis of eco environmental RS in typical regions and the cause and countermeasure on the eco environmental change based on multi temporal RS data comparison.Furthermore,the author systematically reveals the law of the spatial distribution,spatial statistics and spatial characteristics in the form of quantitation.
