The water ecosystem, an essential component of the United Nations Sustainable Development Goals, faces challenges such as water scarcity. Resilience is one of the central objectives of sustainable development. This study aims to investigate the water ecosystem resilience in Tianjin, providing a reference for protecting and restoring the global water ecosystem. Using the DPSIR model, an evaluation system for water ecosystem resilience was constructed. The combination weighting method was used to determine the weights of evaluation indicators. A case study on the water ecosystem resilience of Tianjin reveals spatial differences in 2018, with higher resilience in the north, and lower in the south. From a spatial planning perspective, forest coverage and wetland rate are representative evaluation indicators that significantly impact Tianjin's water ecosystem resilience. The overall connectivity index analysis method was used to analyze the representative evaluation indicators, and enhancement strategies such as building forest cities and protecting and restoring wetland systems were proposed. This study provides theoretical support for improving the water ecosystem and technical guarantees for achieving sustainable development.

摘要

The water ecosystem, an essential component of the United Nations Sustainable Development Goals, faces challenges such as water scarcity. Resilience is one of the central objectives of sustainable development. This study aims to investigate the water ecosystem resilience in Tianjin, providing a reference for protecting and restoring the global water ecosystem. Using the DPSIR model, an evaluation system for water ecosystem resilience was constructed. The combination weighting method was used to determine the weights of evaluation indicators. A case study on the water ecosystem resilience of Tianjin reveals spatial differences in 2018, with higher resilience in the north, and lower in the south. From a spatial planning perspective, forest coverage and wetland rate are representative evaluation indicators that significantly impact Tianjin's water ecosystem resilience. The overall connectivity index analysis method was used to analyze the representative evaluation indicators, and enhancement strategies such as building forest cities and protecting and restoring wetland systems were proposed. This study provides theoretical support for improving the water ecosystem and technical guarantees for achieving sustainable development.
