摘要
基于多人群视觉感知视角,以紫鹊界龙普梯田群为研究对象,借助眼动试验、图像语义分割技术、稳健地理探测器等方法分析风景要素、风景结构与视觉感知之间的交互作用。研究提取出“小起伏农田植被景观”等6类基础风景类型,发现起伏度、农田(梯田、园地)作为重要的风景要素对人群视觉感知具有直接作用,贡献率为9.45%、7.05%;“农田与起伏度”“农田与建筑”作为风景主体结构时对人群视觉感知具有更强烈的作用力,贡献率为28.53%、28.22%。结合基础风景类型的分布情况,可知高美景度风景区域主要位于地形起伏度35~118 m,植被覆盖度为18%~60%,以梯田农业景观为主,以聚落景观为重要视觉焦点。研究认为保护、应用具有地域特色的风景要素及结构,解析其中的形态韵律与作用关系,有益于推进紫鹊界龙普梯田群保护与乡村生态旅游发展。
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 techniques,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-farmlandvegetation landscape"were extracted.The research revealed that undulation and farmland(terraces,orchids)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"farmland 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 application of landscape elements and structures with regional characteristics,and the analysis of the of their morphological rhythms and functional relationships are conducive to promoting the protection of the Longpu rice terraces in the Ziquejie and the development of rural ecotourism.
