Land use is a result corresponding to long-term engineering work and cultivation conducted by human beings on lands in accordance with natural feature and social demands; dynamic changes in circumstances affect engineering work behind land deployment, plus human activities used to be powers building up factors to effects of changes in circumstances. Due to reason that Geographic Information Systems (GIS) is equipped with functions which include integration of figures in space and properties, overlay analysis, presentation, hence, incorporation of database in pattern of land deployment applied on GIS helps a lot on information acquirement for current condition of land deployment and progress in dynamic changes. This Study introduces concepts of Landscape Ecology applied on integration and revision of charts presented in different time in Yunlin County through technology in space analysis of GIS; in addition, in terms of Grey System Theory, this Study not only explores correlation between versified patterns of Land use, but also predicts changes of agriculture lands of future in Yunlin County. Indicated by the findings in this Study, quantity of agriculture lands occupied in the largest area of the whole county was in upward trend, but excluded area, Show Yunlin County agricultural land with scattered, broken from happening, suggesting the influence of factors from agricultural land use changes. In addition, transportation and construction lands are in trends of expansion ， issues of development in transportation and construction lands cannot even be ignored. Suggesting the influence of factors from Yunlin County land use towards urbanization, more emerged in Yunlin County land use by increasing the degree of human disturbance. However, regarding to predictive analysis, the changes in area of agriculture lands then rise up gradually in Yunlin County. Suggesting the influence of factors from the rise of the coffee industry, prompting the forest land transferred as a coffee farm. Finally, suggestions Decision maker of how to improve the planning and make the use of the land resources to be sustainable in Yunlin County.
