In this paper, an analysis of the spatial and temporal landscape evolution of northwest Sichuan Province, China, is carried out based on the landscape theory, RS and GIS. Fucheng District in Mianyang City, Sichuan Province, is chosen as our study area, and the driving forces of its landscape evolution are discussed based on the land use maps, the Landsat TM/ETM+ and CBERS 2B remote sensing images...
Land degradation is an important environmental problem, it will become a threat to food security and the sustainable development of socio-economic systems, ultimately affecting the development of humans with global warming. Xinjiang is a key region in China, in which land degradation is very serious. Combed RS with GIS technology, based on the latest remote sensing data, analyzed the spatial distribution...
Shanghai has experienced rapid urbanization over the past three decades. With the rapid development and expansion of city, the physical characteristics (such as land cover types, surface albedo and so on) and property of the urban underlying surface are undergoing substantially changes, which significantly impact the climate and ecological environment. Based on the Landsat TM remote sensing imagery,...
This paper analyzed the spatial pattern of cultivated land conversion in the Coastal Area of Pearl River Estuary based on RS and GIS technology. The results showed that the cultivated land area reduced rapidly under the pressure of urban expansion, and it was the main period about the cultivated land to reduce from 1988 to 1995. Other types of land also were converted to the cultivated land, which...
In this study, the decision tree (DT) classification technique was used to detect the land use changes based on the spectral characteristics of the samples and the spatial patterns of the six land use classes for two landsat images for the Shalamulun river catchment of China acquired in 1987 and 2001. And post-classification change detection technique was applied to map land cover changes. For validating...
