(2) Use landscape structure index to study the change process of NCHU. (3) Study the landscape structure and change of campus land use by Markov probability vector and GIS. (4) Use semi-Markov chain with time interval to predict the necessary distribution of campus land use under steady state in the future. Per this study the campus administrator can have a reference for planning campus land use in the future. The result of this study was mentioned below: (1) We interpreted the aerial photographs of the campus at different periods（1973,1982,1990,1995,2001） with 21μorthogonal digital images, this study use GIS function filter and overlap to get the information of landscape change in land use. This study separate land use to 5 parts: “green land”, “buildings”, “roads”, “wasteland”, and “water”, and get the basic attributes of the land use. The total area of land use from every single year is same in the convenience of successive studies. (2) The results of campus landscape structure index shows that from 1982 to 1990 the land use changed because of the campus public constructions. It merges the fractal patches by planning and causes the mean patches size (MPS) larger. The campus land use in 1973 shows non-organized, and causes the patch density (PD) larger. Totally speaking, the SHAPEI and FRACT values perform less change and these mean the campus are well-developed.. (3) By solving Markov chain probability vector, the stable probability vector in 1995 to 2001 is the land use stable probability vector in the campus. The result is: the other land changed to green land area proportion: 41.937%, buildings: 34.723%, road: 21.269%, wasteland: 0.518%, water: 0.553%. The result shows the campus land use is almost stable, and the present state of the land use is saturated. (4) From the time process of Semi-Markov chain, the result of future campus land use proportion is: green land: 54.8253%, buildings: 30.8517%, road: 14.0612%, wasteland: 0.03194%, water: 0.22984%. By this result, the green land will occupy larger proportion in the campus future land development. The planner should take the green land as the main sort of land use in the future. Totally, campus land use development under steady-state is a fixed proportion, especially from this study results, the steady-state proportion of land use distribution may use the “green land” as the main part, and add the use area of “buildings” would be suggested. Plan the outdoor plain area transferring to the “green land” to raise the quality of campus environment.
