ANALYSIS OF THE EXPANSION OF THE BUILT-UP AREA OF DALIAN CITY

With the astounding development and gradual improvement of remote sensing technology, as an advancedscience technology, it is used to provide multi-temporal, large scope real-time information for land-use dynamic change,and also is one of the best efficient methods for studying the earth resources and environment. Remote sensing image has its characteristics of ample information and reflecting the objective realities. The paper uses multi-temporal TM inages in 1986, 1996 and 2000, and relevant statistic data to analyze land-use changes of Dalian City in Liaoning Province of China over ten years by means of the correlation analysis method. The results have shown that two methods could conformably reflect the present land-use change. Urbanization is closely correlative to natural factors and economic development.
