[Objective] To study the changes of landscape pattern of the coastal wetlands in Zhuanghe City of Liaoning Province and its driving force for the rational using of coastal wetlands and provide decision support and scientific basis of biodiversity conservation.[Methods] With the remote sensing data of Zhuanghe City in 2000 and 2010 as the basic data, under the support of RS and GIS, landscape pattern index model was used to analyze the change of the landscape pattern and the driving forces in this region.[Results] From 2000 to 2010, the area of the coastal wetland of the Zhuanghe City decreased by 7.44%; NP(number of patches) increased from 3 425 to 3 563 and added by 4.03%, H(landscape diversity index) increased from 0.631 5 to 0.855 4,D(landscape dominance index) decreased from 0.835 9 to 0.736 4, E(landscape evenness index) decreased from 0.578 to 0.514.[Conclusion] The changes of the landscape pattern indices indicated that the fragmentation of the landscape was aggravating. Both artificial and natural forces caused the wetland area reduced, and the ecological function of the coastal wetlands declined, which had worsen the ecological environment of research area, and indeed had seriously affected the economic development of the Zhuanghe City.
