The development of inner harbors has been accompanied by the destruction natural landscapes, which in turn led to numerous ecological problems. However, temporal and spatial relationships between changes harbor landscape effects are not yet clear, there relatively few studies at smaller scales such as villages. In this study, we investigated Xieqian Harbor Xiangshan County, along eastern coast China, then analyzed change evolutionary characteristics carbon storage, soil conservation, water yield village scale for years 2000, 2010, 2020. We used geographically temporally weighted regression (GTWR) model explore spatiotemporal variables effects. results showed that fragmentation diversity patches increased from 2000 2020 due reclamation aquaculture, tourism development, construction, reflected edge density (ED) Shannon index (SHDI), 11.31% 2.82%, respectively. This resulted a notable reduction 572.6 thousand tons sequestration, 853 million 19 cubic meters over past 20 years. When non-stationarity heterogeneity were combined, relationship became highly intricate, with varying responses across different time periods locations. area-weighted mean patch shape (AWMSI) was key factor affecting three Our research confirmed significant on scale. Compared larger-scale studies, village-scale revealed more precisely impacts localized effects, providing support sustainable management new approach integrating GTWR into time–space analysis research.
