The study of tempo-spatial of construction lands in Wuhan: a remote sensing-based approach

摘要

Temporal and spatial evolution of urban built-up areas is an important measure of the urbanization index. a study of analyzes the urban land evolution, then analyzes tempo-spatial of construction lands in wuhan from both qualitative and quantitative, for treatment of four phases Remote Sensing data of wuhan constructed lands by Remote Sensing technology, using the approach of spatial information of superposition. The result shows construction lands expand different and gradualness obviously for urban land development provides supporting reasonable expand of urban lands.
