[Objective] Quantifying and analyzing the value and spatiotemporal changes of ecosystem services in the key coupling zone of mountain-river-sea is helpful to understand the current situation of ecosystem services, and then clarify the trade-off / synergy relationship between ecosystem services in the key coupling zone of mountain-river-sea. It is of great significance to improve the understanding of the interaction between ecosystem services and promote the comprehensive sustainable development of the region and the protection and restoration of ecological environment. [Methods] Based on the landuse data from 1990 to 2020 and the revised equivalent factor table, the grid method and geographically weighted regression were used to analyze the spatial and temporal changes of ESV and the relationship between various ecosystem services and their spatial differentiation characteristics in the mountain-river-sea coupling key zone from 1990 to 2020. [Results] From 1990 to 2020, the total ESV in the key zone of mountain-river-sea coupling increased from CNY 78.855 billion to CNY 79.230 billion, with an increase of 0.48%. The ESV of forest land, cultivated land and water land was higher, which was the main contribution factor of the total ESV in the area. The ESV of construction land was lower, and the ESV showed a trend of decreasing from northwest to southeast in space. From 1990 to 2020, the interrelationships of various ecosystem services were mainly synergistic, accounting for about 85.45%. The high-value areas of trade-offs mainly distributed in the central and southern regions of the mountain-river-sea coupling key zone, and the low-value areas mainly distributed in the karst mountainous area of Baise City; the synergistic low-value areas mainly distributed in urban and coastal areas with dense population, frequent human activities and relatively developed economy. [Conclusions] From 1990 to 2020, the ecosystem services in the key coupling zone of mountain-river-sea were coordinated and maintained a dynamic balance. Food production activities would affect the ability of other ecological services. In the future, local governments should strictly control the development boundary of production activities and pay attention to environmental protection and restoration of production areas.
