Abstract:

The problem of more people and less land and the shortage of cultivated land resources have been a long-term and difficult challenge in China. Comprehensive land consolidation and rehabilitation is an important means to optimize the spatial layout of the land, promote rural revitalization and urban renewal, and realize the integration of urban and rural development. China will promote green development and harmonious coexistence between man and nature in 2021-2025, and the ecological effect evaluation of land consolidation has become one of the hot topics at home and abroad. For a long time, land consolidation and rehabilitation had focused on improving the quality of cultivated land and supporting farmland infrastructure and paid less attention to the impact on ecosystem service value. The research object of this study is Shazai Island, Xinhui District, Jiangmen City, which was the first demonstration project of comprehensive land consolidation and rehabilitation in Guangdong Province. The study employed the ecosystem service value method to explore the impact of comprehensive land consolidation and rehabilitation on the ecosystem service value of the study area. The results showed that the adjustment of land use type and structure before and after comprehensive land consolidation and rehabilitation and the implementation of ecological restoration measures were the key factors in enhancing the ecosystem service value of Shazai Island. After comprehensive land consolidation and rehabilitation, the overall ecosystem service value, economic production, soil protection, wave dissipation and revetment, biodiversity, and habitat protection value of Shazai Island improved by 250%, 587%, 20.2%, and 182%, respectively, while the ecosystem service value of flood regulation and storage decreased by 87%. In terms of spatial distribution, the ecosystem service value and its increase showed the following order: North Island > South Island > periphery of dam area. This study demonstrated that the combination of land consolidation and rehabilitation and ecological protection and restoration could help to improve the ecosystem service function and provide a reference for the evaluation of land consolidation and rehabilitation and ecological restoration.

Key words: comprehensive land consolidation and rehabilitation, ecological effect, ecosystem service value, the Shazai Island, Guangdong Province
