Abstract：Based on the analysis of the 11 ecological monitoring indexes in Changli ecological monitoring area,the water body factors of Changli were subjected to Kriging interpolation by using ArcGIS10.0.The landscape environment,biological environment and environment in Changli area were analyzed by landscape pattern index method.The changes in landscape pattern in Changli ecological monitoring area and the ecological environment effect are analyzed.The relationship between the marine landscape and the ecological process are discussed.The study shows that the human activities have a significant effect on the ecological environment of Changli County in 10 years.The content of N,P in water was high,the eutrophication of water in Changli sea area is serious and the water environment has been seriously damaged.The biodiversity was decreased.The percentages of sandy bottom suitable for the survival of amphioxus were degraded year by year.The biomass of amphioxus was degraded.Mariculture,sand mining and tourism development activities have affected the ecological environment of the sea.It is clear that the management should be strengthened for the environmental capacity of marine aquaculture,the dredging vessels,the protection of fishery resources and the reasonable marine development activities in order to maintain the diversity of marine ecosystems.
