In order to explore the degree and spatial distribution of landscape ecological security in Longyan City, the authors constructed the ecological security assessment index system of Longyan City based on the "pressure-state-response" conceptual model. And the landscape ecological security comprehensive index distribution in 2001 and 2008 was overplayed by means of multi-temporal remote sensing images, GIS techniques and landscape ecological theory. The results showed that, with the increasing of the outside pressures, landscape structure was stable, and landscape vigor and ecological status were both at a good level. The mean value of landscape ecological security index was 7.27 in 2001, which was located at the high level, while in 2008 the index was 6.65, which was at a medium level. Therefore, it is concluded that the landscape ecological security of Longyan City experienced a slight deterioration during the study period. In order to improve the urban landscape ecological security, the authors suggest optimizing the land use pattern in the future urban planning and construction.
