Local residents of buffer zones, as a key factor in the World Heritage conservation and sustainable development, have not received sufficient attention in most developing countries, especially in the mountainous areas where poor and backward ethnic minorities live. To fill this research gap, this paper takes the Karst World Heritage buffer zone in Libo, Guizhou Province, southwest mountainous area of China, as the research area, and explores the factors that influence the perception of residents’ responsibility for the World Heritage conservation by taking local residents who are involved in tourism management as the research subjects. Data were collected in the buffer zone of the Libo World Heritage site and 186 valid data were generated. SPSS 25.0 and AMOS 27.0 software were used to analyze the questionnaire data and construct a structural equation model. The results showed that environmental protection behavior had the greatest impact on residents’ perception of responsibility for heritage conservation (0.93), followed by the recognition of heritage value (0.55), tourism positive impact (0.39), and place identification (0.34), among which the positive impact of tourism had a greater impact on the perception of heritage value (0.52). The results of the study emphasize the importance of the recognition of heritage value and positive tourism influence on the formation of residents’ perception of responsibility for heritage conservation, and provide an empirical basis for the conservation of the World Natural Heritage.

As the protection layer of world natural heritage sites, the buffer zone should enable economic development while protecting the environment. To carry out agricultural activities in the buffer zone, it is necessary to balance agricultural development and environmental protection. In addition, the development of agroforestry has the benefits of developing the economy, maintaining biodiversity, and protecting the environment. In order to promote the coordination of environmental protection and community economic development, it is particularly important to scientifically select agroforestry planting patterns in the buffer zone of world natural heritage sites. This study utilized a mixed-methods research approach that included qualitative and quantitative research. Taking the buffer zone of Shibing Karst Heritage Site in southern China as an example, based on the seven agroforestry planting patterns surveyed in the buffer zone of the world natural heritage site, the four dimensions of net output value, carbon emission, environmental cost, and comprehensive livelihood score of different agroforestry planting patterns were calculated. The sorting scores of the values were calculated as Borda numbers. The sorting scores of the seven agroforestry planting patterns were B(A1) = 17, B(A2) = 18, B(A3) = 8, B(A4) = 8, B(A5) = 14, B(A6) = 12, and B(A7) = 7. The results showed that the priority sequence of seven agroforestry patterns was A2 > A1 > A5 > A6 > A3 = A4 > A7. A2 was the best among the seven agroforestry planting patterns, and A7 ranked last. The results can provide a quantitative evaluation basis for scientific optimization of agroforestry development planting patterns, and provide a reference for promoting the protection of world natural heritage.

In the face of increasing development pressure, how to fulfill the obligations under the World Cultural and Natural Heritage Convention and maintain the integrity of the Natural World Heritage Site (NWHS) is a major problem to be solved at present. Agroforestry (AF) development in the buffer zone maintains the integrity of NWHS and promotes sustainable ecological and economic development in the buffer zone. Still, few studies on the knowledge system of integrity protection of NWHS and AF development in the buffer zone research have been conducted. To fill this gap, this study conducts a systematic literature review based on 128 related articles retrieved from the Web of Science (WoS) database and the China National Knowledge Infrastructure (CNKI) database. Firstly, quantitative studies were conducted to analyze the annual numbers, content and study regions of the published literature. Secondly, the main research progress and achievements of integrity protection of WNHS and AF development in the buffer zone are classified and summarized. On this basis, this paper proposed key scientific issues that remain to be addressed in future, as well as exploring the implications for the World Heritage (WH) karst. This study is a scientific reference for the balanced development of NWHS integrity protection and AF in the buffer zone.

This SALSA-based review of 197 WoS and CNKI articles synthesizes advances and gaps in SESR theory, methods, model construction, empirical demonstration, and benefit evaluation. It examines how resilience thinking may inform a shift from static conservation to adaptive management in Karst World Natural Heritage buffer zones, while clarifying the conditions under which SESR insights may be relevant to uncertainty, conservation-development tensions, and long-term heritage sustainability.

Clarifying how cross-boundary linkages between the core areas and buffer zones of World Natural Heritage Sites (WNHSs) are transformed into conservation–development synergy is a key scientific question for reconciling heritage conservation and community development beyond static zoning governance. Taking the Libo Karst World Natural Heritage Site (KWNHS) as a case study, this study develops a spatial linkage–social transformation–conservation–development synergy framework based on survey data from 253 residents across seven villages and integrates PLS-SEM, NCA, and fsQCA to identify net effects, necessary conditions, and configurational pathways. The results show that tourism–economic linkage promotes synergy through both direct effects and value transformation, whereas organizational linkage operates mainly through governance transformation via community participation. Ecological linkage contributes primarily through heritage identity. Cross-method analysis further reveals that benefit feedback represents a relatively weak but significant necessary constraint and a core condition across high-synergy configurations, while heritage identity represents a stable value foundation. These findings demonstrate that spatial linkages generate conservation–development synergy only when they are effectively transformed into benefit sharing, participatory governance, and shared heritage values.
