Metrological Analysis of Landscape Aesthetics Literature based on CiteSpace

With the deepening development of ecological civilization construction in China, eco-tourism, forest recreation and natural landscape resources development and so on have gradually become important ways for all regions to practice the new development concept of "green mountains are gold and silver mountains" and realize the transformation of ecological value. Landscape aesthetics has been integrated into traditional disciplines such as forestry, ecology and landscape architecture, etc. Quantitative evaluation of landscape aesthetics value has become a key indicator of ecosystem service value accounting and landscape design, and has become a hot field of relevant research. Based on Cite Space software, using bibliometrics and other methods, the research hotspots and development trend in this field at home and abroad were analyzed from the perspectives of annual publication volume, main keywords, landscape types, research methods and so on respectively, from 1048 landscape aesthetics research literatures collected in CNKI database and 1455 landscape aesthetics research literatures collected in Web of Science core collection. The results showed that the research on landscape aesthetics in China started late, and the output of scientific research had increased significantly in recent years, but there was still a certain gap compared with the international research. The types of research objects were forest landscape and urban landscape. Foreign countries mainly focused on natural ecological landscapes such as wetlands and wilderness, while domestic countries tended to small-scale landscapes, with limited research horizons. Domestic research focused on the social value of landscape beauty, landscape planning and allocation, while international research paid more attention to the ecological value and cultural value of landscape aesthetic resources. In domestic landscape aesthetics, there were some problems such as scattered research directions, strong subjectivity of evaluation methods and weak innovation of achievements. In the future, it is suggested to strengthen interdisciplinary integration and international cooperation, improve the research system of landscape aesthetics, update research techniques and methods, and emphasize the research on the transformation of landscape aesthetic values.
