Historic Cultural Landscape Service Evaluation and Zoning Management Strategy Based on Poetry Text: A Case Study of Fuchunjiang Historic River Corridor

Historic river corridor is an important part of social ecosystem. It is of great significance for urban planning in contemporary society to identify the HCL (historic cultural landscape) service level of historic river corridors, and to delimit the spatial scope of and provide zoning management strategies for HCL services provided by historic river corridors. Taking Fuchunjiang historic river corridor as an example, this research constructs a diachronic data model to evaluate the total of HCL based on poetry text and, from the perspective of long time-series, predicts the service value of HCL through makima function extrapolation, and estimates the potential of HCL through HCL potential model. On this basis, the research areas are divided into four spatial types using the “total-potential” distribution model, and provides zoning management strategies in combination with the time-series analysis results of three HCL indicators. The results show that Fuchunjiang historic river corridor can be divided into the following four areas: core area with high total and high potential, protection area with high total and low potential, renewal area with low total and high potential, and supplementary area with low total and low potential. In Fuchunjiang historic river corridor, the spaces with the highest general level of HCL supply are concentrated in the riverside areas around Yan Ziling Fishing Platform, Qililong River and Tongjun Mountain. From the perspective of long time-series, the research develops relevant methods for identifying, predicting and classifying HCL service supply spaces from the two dimensions of HCL total and potential, providing a clear and repeatable technical path for HCL protection and management of historic river corridors.
