As a World Cultural Heritage site, the Beijing–Hangzhou Grand Canal is lined with historic and cultural cities that bear abundant historical and cultural connotations. It is of vital importance to address the issues of landscape homogenization, the disconnect between conservation measures and public needs, and other related challenges in the development of these cities. This study adopts a mixed-methods approach combining qualitative and quantitative research. By integrating subjective landscape evaluation with eye tracking analysis, the ancient city of Taierzhuang along the Beijing–Hangzhou Grand Canal was selected as the research subject to conduct an in-depth investigation into the visual experience and preferences for different types of landscapes in this area. The study yielded the following findings: There are significant differences in visual experiences among various types of landscapes in Taierzhuang Ancient City. Among them, participants exhibited the highest level of attention toward canal landscapes and the lowest toward heritage site landscapes. In terms of visual distribution differences, eye tracking heatmaps revealed that attention was primarily concentrated on architectural structures and water surface reflections. In the subjective evaluation analysis, canal cultural landscapes received the highest comprehensive score (4.39 points), followed by historical architectural landscapes (4.02 points), historical street landscapes (3.93 points), modern commemorative landscapes (3.72 points), and heritage site landscapes (3.69 points). Additionally, a significant correlation was found between eye tracking data and subjective evaluation results, validating the scientifically effective relationship between subjective assessments of historical cultural landscapes and eye tracking analysis. The findings of this study not only provide a scientific basis for landscape improvement and optimization in other canal-related historical and cultural cities but also offer new research methods and perspectives for the protection and development of other heritage landscapes.

The rural landscape, as the core constituent unit of rural space, is vital for promoting sustainable rural development and achieving rural revitalization goals. However, current research is often limited to single groups, neglecting differences in visual behaviors (VBs) and landscape preferences (LPs) among diverse groups. Thus, this study employed eye-tracking technology combined with a landscape preference questionnaire to investigate the VBs and LPs of 160 participants when viewing rural landscapes. The results indicate that there is a notable correlation between VBs and LPs (p < 0.01), and the two aspects mutually influence each other. Moreover, groups with different demographic characteristics exhibit significant differences in both VBs and LPs. Among them, the score for LPs in the group of farmers, service sector workers, and retirees is significantly higher than that in the group of students, while the mean fixation duration is significantly lower than that in the group of students. Based on these research findings, this study suggests that, during the process of rural landscape design, full consideration should be given to the VBs and LPs of diverse groups with different demographic characteristics to enhance the inclusivity of rural landscape design and facilitate the realization of diversified and sustainable rural development.
