In order to provide the scientific basis for rational resources utilization and ecological environmental protection of West Taiwan Straits Economic Zone,the paper analyzed the ecosystem composition and the landscape pattern characteristics of the region in 2008using the spatial pattern index method of landscape ecology combined with remote sensing and GIS technologies.The results indicated:(1)West Taiwan Straits Economic Zone was mainly composed of forest,grassland,farmland,waters,wetland,urban land and some barren land with significant difference of elevations;(2)The predominant landscape is forest distributed concentratedly, while grassland and farmland are very important with a larger quantity of patches scattered in the whole area,and urban land and barren land have no good patterns,which are significantly influenced by human activities;(3)Water bodies are very stable with significant difference of shapes;(4)The natural factors such as the precipitation and air temperature are the main elements which impact the landscape patterns in the region while the human activities are less important.
