英文摘要	In this study,to understand the spatio-temporal evolution of mariculture in typical tidal flat wetlands,based on remote sensing and sea area use confirmation data obtained,using GIS spatial analysis methods,we analyzed the space evolution process of pond aquaculture and ocean aquaculture in the Yellow River Delta region from 1985 to 2020.We also investigated its impact on the wetland structure and landscape pattern of tidal flat wetland resources.The results revealed that before 2010,the scale of aquaculture in terrestrial ponds in the region increased,with the maximum area being 1 480.1 km~2;two growth peaks were observed in 1985-1990 and 2000- 2005.After 2010,the area of pond aquaculture began to decrease,while open ocean aquaculture developed rapidly that the average annual growth rate was 84.9 km~2·a~(-1) from 2007 to 2019,and reached 1 601.8 km~2 in 2019.The spatial distribution of aquaculture showed a growth from the tidal flat wetlands toward the offshore waters in the land-ocean gradient,and the spatial centroid of aquaculture ponds continued to migrate to the northwest of the region after 1990.The cumulative increase in mariculture area led to a reduction in 1 011.7 km~2 of tidal flat resources,which resulted in a decrease in the proportion of area of tidal flat wetlands to that of marsh wetlands from 53.5% at the beginning of the period to 15.2%,and the complexity and heterogeneity of regional wetland landscapes increased.This study concluded that the spatial growth of mariculture in the Yellow River Delta region exhibited obvious temporal fluctuations.Around 2010,the focus of spatial increase shifted from pond aquaculture to open ocean aquaculture.The increase in space for aquaculture in terrestrial ponds has led to a large-scale reduction in coastal tidal flat resources and has promoted continuous outward movement from coastal tidal flats to offshore waters.In addition,it has aggravated the fragmentation of natural wetlands and led to balanced development of human-made and natural wetlands in the Yellow River Delta region.
