Identifying Potential National Park Locations Based on Landscape Aesthetic Quality in the Hengduan Mountains, China

Abstract

Landscape aesthetic quality (LAQ) evaluation is vital in territorial spatial planning. It helps to achieve the rational development and protection of territorial space and ensures the harmonious coexistence of developments and the ecological environment. Based on mapping and quantification, this paper took LAQ evaluation as the object, established a methodological framework for large-scale natural LAQ evaluation, excavated and identified key areas with outstanding landscape aesthetics service supply capabilities, and supported regional landscape planning and protection management. This paper took the Hengduan Mountains in China as an example to evaluate and identify the spatial distribution of the LAQ in mountainous areas. The results showed that the high-value LAQ areas are located east and south of the Hengduan Mountains, where high-quality natural landscapes are concentrated and have significant potential for establishing national parks. The evaluation results of the LAQ can provide a good reference for the spatial identification of future national parks in the Hengduan Mountains. Moreover, our research can provide a scientific basis for large-scale landscape spatial planning and decision-making for the classified protection and rational utilization of landscape resources and other mountain ecosystems.
