Taking Landsat5/TM images of 1988, 1997 and 2005, this paper used RS and GIS to analyze the changes of ecological environment effects of land use/cover change (LUCC) during the recent 17 years of the study area. The results indicate that: swamp land shows obvious decreasing trend and decreases 1674km2; dry land and paddy land shows strong increasing trend and increase 377km2 and 1338km2 separately...
Based on Geographic Information System(GIS)and Remote Sensing(RS), the landscape-change is analyzed in Huang-hua wetland form 1997 to 2007, and the influence on environment was evaluated due to the landscape transit based on eco-environment quality index and contribution rate. The main results and finding include that the environment of Huang-hua Wetland was destroyed,the eco-environment quality index...
Addressing the question dasiaIs the world urbanizing in a context of poverty?psila has been so far based on limited information. There is only poor scientific and operational knowledge of this process. Urban growth & land consumption patterns are poorly understood (i.e. coastal cities are growing faster; they are disproportionately urban and with higher densities). Thus, the available information...
It can serve for the city planning scientifically and improve the people's knowledge about the detailed surroundings by evaluation of urban environment status from high resolution satellite images. Environmental factors such as vegetation type and coverage, water area and water pollution can be known from the images directly, the population density can be calculated from the building structure, the...
