Participatory mapping of cultural ecosystem services for landscape corridor planning: A case study of the Silk Roads corridor in Zhangye, China

Cultural landscape corridors provide opportunities for recreation and other cultural ecosystem services (CES). Currently, many local governments are preparing cultural landscape corridor (CLC) proposals along China's Silk Roads, which include many notable features of historical human activity and communication between different cultures. However, public values and perceptions of these projects have been largely excluded from the planning processes. This study presents a spatial pattern analysis of public perceptions of the impact of a CLC in Zhangye, China. CES were used as a framework for participatory mapping, interviews, and a structured survey of public perceptions, and correspondence analysis was used to identify resident perceptions of the corridor's expected impact, especially as related to CES. Our results show that aesthetic values, cultural heritage values, and recreation were valued most highly. These values varied according to respondents' employment and land-use rights. The riverside was the most highest-valued area for CES. Respondents expressed concerns about the project's potentially negative impact, especially on the spiritual values of land. These concerns could be the source of conflict during project implementation. We conclude that linking participatory mapping with CES has the potential to improve corridor proposals and assist in the management of conflicts between planners and public stakeholders.
