[Objective] Studying the law of regional ecological risk changes in coastal areas in order to provide theoretical reference for ecological rehabilitation.[Methods] Taking the coastal area of Fujian Province as the research object

using geostatistical analysis and spatial auto-correlation analysis method with ArcGIS and Fragstats software

we constructed a landscape ecological risk assessment model based on the ecological environment vulnerability and loss degree of land use change. The distribution of ecological risk levels in the study area and the spatial correlation of ecological risks were analyzed.[Results] The areas of construction land

forest land

and water area all showed an upward trend

and the areas of shrubs

grassland

cultivated land

mudflats

and unused land all showed a downward trend

and the degree of fragmentation got worsened

the degree of separation was increased. The degrees of fragmentation and separation gradually decreased

and the geographical distribution gradually became concentrated. The spatial distribution of ecological risks in 2000-2013 was roughly in a banded pattern

and the areas at low

lower

and middle ecological risk levels all increased but with different increments. The areas at high and higher ecological risks both had been reduced to some extent. The ecological risk index in the study area had a strong agglomeration effect in space

and the spatial distribution of ecological risk indexes was mostly in high-high and low-low patterns.[Conclusion] The overall ecological risk showed a downward trend

and the ecological environment gradually improved. However

the landscape ecological problems are still severe. Therefore

the government departments must pay attention to the local ecological environment while developing economy

and realize the coordinated development of economy and ecological environment.
