Abstract:Marine is of key importance for the development of China's economy and society, but encounters resource constraints, serious environmental pollution, and the degradation of ecosystem. Therefore, the establishment of monitoring and early-warning mechanism on the carrying capacity of marine resources and environment is of great urgency. In this work, a DPSIR conceptual model and relevant index system were established, to evaluate the carrying status of regional marine resources and environment on county-level, and to assess whether it is overloaded. The established measuring strategy was applied to the Tianjin and Hebei coastal area, the results revealed that the regional carrying capacity was overloading, and marine ecosystem degradation, coastline over exploration, coastal water pollution, and over fishing were the main influencing factors. More efforts are expected for further development on the comprehensive measuring strategy of carrying capacity of marine resources and environment, and effective ways to relieve anthropogenic pressures and to improve carrying capacity for regional marine ecosystem.
