Modeling of the Ecological Carrying Index of reclaimed land in coastal city: A sustainable marine ecology perspective.

In recent years, Wenzhou City located on the southeast coast of China has experienced the largest scale of land reclamation projects in China. However, the extent to which such projects still bring about the destruction of marine resources and the environment. So, in this study, a marine ecological development carrying capacity index model was established and analyzed the ecological carrying capacity index of the reclaimed sea area in Wenzhou with the detection and warning conditions to propose a marine ecological protection supervision mechanism. By the proposed mechanism, five primary-level indicators and 10 corresponding secondary-level indicators were established. The obtained results showed that the ecological carrying index of the reclaimed area in Wenzhou falls within the range, 2.35-5.45, which is indicative of small geographic differences. These results suggest that in future, a detection and early warning mechanism for the determination of the ecological carrying capacity of reclaimed sea areas should be established. Furthermore, the strict implementation of the reclamation project development evaluation management control system is recommended, and it is also necessary to reasonably adjust the planning and construction of the sea area.
