Visual Perception Characteristics and Influence Factors of Rural Landscapes——An Example of the Longpu Rice Terraces in the Ziquejie of Hunan Province
Based on the perspective of multi-crowd visual perception,the Longpu rice terraces group in Ziquejie were used as the research objects.Eye movement experiments,image semantic segmentation tech-niques,robust geographic detector and other methods were used to explore the interaction among landscape elements,structures and visual perception.Six basic landscape types such as"small undulating-farmland-vegetation landscape"were extracted.The research revealed that undulation and farmland(terraces,or-chids)had direct impacts on crowd visual perception as important landscape elements,with contribution rates of 9.45％and 7.05％.As the main structure of the landscape,"farmland and undulation"and"farm-land and architecture"had stronger impacts on the visual perception of the crowd,with a contribution rate of 28.53％and 28.22％.Combined with the distribution of basic landscape types,it could be seen that the scenic area with high beauty degree was mainly located in the range of terrain undulation 35-118 m,and the vegetation coverage reached 18％-60％.The area was dominated by terraced agricultural landscape,and the settlement landscapes was an important visual focus.It is believed that the protection and applica-tion of landscape elements and structures with regional characteristics,and the analysis of the of their mor-phological rhythms and functional relationships are conducive to promoting the protection of the Longpu rice terraces in the Ziquejie and the development of rural ecotourism.
