Chinese classical gardens serve as restorative environments that epitomize the essence of Chinese aesthetics. Despite their recognized Outstanding Universal Value, research on the multisensory experiences and associated well-being benefits they offer remains insufficiently explored. This study examines the Humble Administrator’s Garden through a multisensory framework incorporating visual, auditory, and tactile dimensions. By employing a mixed methods approach that integrates questionnaires and physiological measurements, we assessed the psychophysiological responses of 78 participants before and after entering the garden, as well as at distinct landscape points. Key findings reveal the following: (1) the traditional garden environment evoked significant positive perceptual effects; (2) the garden, with its diverse combination of landscape elements—including architecture, water features, rock formations, and plants—was strongly associated with enhanced well-being outcomes. A higher diversity of visual landscapes yielded more pronounced benefits, with water features exerting the most substantial positive influence on health, while rock formations showed a comparatively lesser effect; and (3) physiological and psychological responses of participants varied within the same landscape setting, with tactile experiences eliciting the most profound psychological changes. These findings underscore the pivotal role of multisensory engagement in Chinese classical gardens for fostering well-being, offering valuable health-related benefits beyond their cultural and ecological significance.

Xishu Gardens, an exemplary narrative of classical Chinese gardens, faces challenges in preserving its commemorative spatial structures while accommodating modern visitors’ needs. While trajectory analysis is critical, existing studies struggle to interpret multi-dimensional perception-preference data owing to spatiotemporal mismatches in multi-source datasets. This study adopted an improved Ward–K-medoids hybrid clustering algorithm to analyze 885 trajectory samples and 34,384 synchronized data points capturing emotional valence, cognitive evaluations, and dwell time behaviors via panoramic digital twins across three heritage sites (Du Fu Thatched Cottage, San Su Shrine, and Wangjiang Tower Park). Our key findings include the following: (1) Axial bimodal patterns: Type I high-frequency looping paths (27.6–68.9% recurrence) drive deep exploration, in contrast to Type II linear routes (≤0.5% recurrence), which enable intensive node coverage. (2) Layout-perception dynamics: single-axis layouts maximize behavioral engagement (DFTC), free-form designs achieve optimal emotional-cognitive integration (WTP), and multi-axis systems amplify emotional-cognitive fluctuations (SSS). (3) Spatial preference hierarchy: entrance and waterfront zones demonstrate dwell times 20% longer than site averages. Accordingly, the proposed model synchronizes Type II peak-hour throughput with Type I off-peak experiential depth using dynamic path allocation algorithms. This study underscores the strong spatial guidance mechanisms of Xishu Gardens, supporting tourism management and heritage conservation.

As an important part of world cultural heritage, waterscapes in Chinese classical gardens are renowned for their unique design, rich cultural connotations, and distinctive esthetic value. However, objective studies of their impact on mental health are lacking. This paper focuses on Xishu Garden, a Chinese classical garden, and examines four types of waterscapes (for a total of twelve) using eye-tracking technology and the Perceived Restorativeness Scale (PRS). The aim of this study is to explore the restorative effects of different types of waterscapes with visual and audiovisual conditions, with particular attention paid to their mechanisms of action. The research results indicate that (1) waterscapes with an audiovisual interaction have a greater restorative value; (2) dynamic waterscapes have greater visual appeal than still landscapes do, but the latter have stronger environmentally restorative effects; and (3) the visual behavioral characteristics of waterscapes change during audiovisual interactions. This study contributes theoretical support for the maintenance and enhancement of Chinese classical gardens and the planning and design of modern urban green spaces, and it enriches our understanding of the role of waterscapes in restorative environments.

Amid growing “nature deficit” associated with urbanization and indoor living, flowering plants are increasingly used to support psychological restoration. Yet evidence on how floral color and structural morphology jointly shape restorative outcomes remains limited. This study employed a within-subjects, repeated-measures design, utilizing physiological instruments and psychological questionnaires to investigate the physiological and psychological restorative benefits of Hydrangea macrophylla and to quantify the differences in restorative effects across five colors (blue, pink, white, mauve, red), two inflorescence types (mophead, lacecap), and two petal structures (single, double). Twenty-eight healthy young adults viewed 15 live hydrangea stimuli under controlled laboratory conditions. Multimodal outcomes combined objective measures—eye-tracking and single-channel EEG—with subjective measures (SD; POMS). Hydrangea exposure significantly reduced negative mood, and color and structure exerted distinct and interactive effects on visual attention and arousal. Red and mauve elicited larger pupil diameters than white and pink, while lacecap inflorescences were associated with lower cognitive load and improved attentional recovery relative to mophead. Double-petaled forms showed greater attentional dispersion than single-petaled forms. Interactions indicated that morphology modulated color effects. The mauve lacecap double-flowered cultivar (M02) showed the strongest observed restorative potential within this sample. These findings highlight the importance of integrating color and structural cues when selecting flowering plants for restorative environments and horticultural therapy, and they motivate field-based replications with broader samples and higher-density physiology.
