| Abstract |
Marine net primary productivity (NPP) plays an important role in regulating marine ecosystem processes, determining marine carbon sinks and maintaining marine productivity. Analyzing the characteristics and mechanisms of the interaction between overexploitation of fishery resources and the transformation of marine NPP is essential to balance marine ecosystem health and fishing activities. This study spatially overlaps the abrupt shifts of human-induced marine net primary productivity detected by breaks for additive season and trend (BFAST) algorithm with fishing activities and investigates the impact of human activities on the marine ecosystem. The results show that 47.60% of the marine areas in China’s exclusive economic zone (EEZ) had detected human-induced NPP turning points (TPs), with 43.65% of the TPs showing a negative reversal (NR) trend. The NR trend occurs in areas with high fishing intensity. High-intensity fishing activities and vulnerability to productivity and NPP TPs in the Bohai and Yellow Sea areas in China’s EEZ exacerbate spatial disparity in fishing effort and product availability. By detecting the abrupt shifts and change characteristics of marine NPP, and spatial disparity overlapping with fishing activities, this study provides some area-based sustainable solutions to support ecosystem-based fisheries management. |
