Abstract: Agricultural cultural heritage is an important carrier of rural culture, encompassing the unique characteristics of China's agricultural history and the great agricultural wisdom of the working people, and tourists' tourism perception is of great research significance to the heritage protection of agricultural cultural heritage sites and the sustainable development of rural culture. This paper takes the agricultural cultural heritage site of Biluochun tea fruit complex system in Wuzhong, Jiangsu Province, as the research object, and analyses the tourists' perceived image of this agricultural heritage site landscape based on crowd sourcing data. The results show that this agricultural and cultural heritage site has the general characteristics of strong perception of material culture landscape and weak perception of non-material culture landscape; the spatial distribution of the main perceptual image shows obvious clustering and dispersal characteristics, which is concentrated in the vicinity of the developed mountains or ancient villages, and the heritage elements have not yet become the core of tourists' perceptions, which needs to be further improved. Based on this, the article proposes cultural protection and township construction strategies for agricultural cultural heritage sites from the perspective of landscape construction, with a view to providing ideas and references for rural construction and agricultural cultural heritage protection.
