Discussing spatial and temporal relationships between land use intensity and the value of ecosystem services in coastal wetlands provides an important foundation to promote the rational allocation of coastal wetland resources and the sustainable development of ecosystems. Based on an equivalent factor method and four periods of Landsat TM remote sensing data of the northern Liaodong Bay (1985, 1993, 2002, and 2014), this paper uses geostatistical methods and a geo-weighted regression model to study the spatial and temporal relationships between land use intensity and the value of ecosystem services based on the calculation of the comprehensive index of land use intensity in the study area. The results showed that: 1) from 1985 to 2014, the value of ecosystem services changed significantly, and the largest value was associated with the water area, followed the beach and grassland areas. Aquaculture provided more and more value, while bare land provided the least. 2) In the study area, the value of ecosystem services per unit area has spatially evolved from high value in the south and low value in the north to high value in the west and low value in the east. The ecological advantages of the southern area gradually weakened and eventually disappeared. 3) There was a strong negative correlation between land use intensity and the value of ecosystem services. As land use intensity increased, the value of ecosystem services decreased. 4) With the increase of land use intensity, there was a trade-off relationship among the four service types, that is the value of other service types decreased due to the increase of supply service value. The correlation between land use intensity and the value of ecosystem services was stronger in the southern part of the study area.
