Synergy and regulation of the South China Karst WH site integrity protection and the buffer zone agroforestry development

Abstract

The Natural World Heritage site (NWH) has a dual role of protection and utilization. The buffer zone of the South China Karst (SCK) World Heritage (WH) site is scattered with village dwellings, which adds pressure to preserve the outstanding universal value (OUV) and integrity protection of the WH site. The development of agroforestry is an essential means to maintain rural livelihoods, protect the ecological environment, and realize the protection and development of the heritage site. Studying the synergy and regulation of the heritage site integrity protection and the buffer zone agroforestry development is essential. This study takes the Shibing and Libo–Huanjiang karst WH as the study areas and administrative villages as the evaluation unit. From 2020 to 2023, through data methods such as remote sensing data interpretation, information data survey and collection, comprehensive index analysis, coupling coordination degree model, and GIS spatial analysis, a systematic study was conducted on the basic frontier research, synergy relationship, and regulation of the heritage site integrity protection and the buffer zone agroforestry development. The results demonstrate that the Shibing and Libo–Huanjiang karst WH sites integrity protection and agroforestry development in the buffer zone have a high coupling degree and a good coupling coordination relationship. This reveals that the heritage site integrity protection and the buffer zone agroforestry development are an interconnected and mutually influential whole, which the synergistic relationship between them is developing in a positive direction; The buffer zone agroforestry development lags behind the heritage site integrity protection, based on which proposed the regulatory measures for the synergy development of the heritage site integrity protection and agroforestry development in the buffer zone. The findings in this study provide references for the synergies development of the WH karst site integrity protection and agroforestry development in the buffer zone.
