Investigating the comprehensive quality and differences in five senses experience along different healthcare trails is particularly crucial for the selection and design planning of trails. Three types of covered space, semi-open space and open space in the healthcare trails of Beijing Xishan National Forest Park and 9 different configuration modes of spatial community structure of surrounding plants[trees-shrubs-grass (F), trees-grass (B), shrubs-grass or grass (K)] were selected and comprehensively evaluated the autumn landscape quality from the five sensory experience factors of touch, smell, vision, hearing and taste. Results show that as follows. For olfactory factors of each trail in autumn, the concentration of negative ions varied from 650 ~ 1 480 cm-3, and the average concentration of negative ions is in the order of covered space > semi-open space > open space > blank control point, the highest average concentration in the covered space is 1 197 cm-3. The average range of human comfort index of tactile factor of different trail types in autumn is 5.13 ~ 6.21, which reaches the "relatively comfortable" level (level 2) on the whole, and the "comfortable" level (level 1) in some periods; Most of the acoustic environmental sound level values in the functional areas of auditory factors of trail types are Class 1 (above 50 dB), and a few reached Class 0 (below 50 dB) standard sound level. Except for certain open space trail types, the green visual factor rate of most trail samples is more than 25%, with the highest rate reaching 65% in covered space types, meeting the requirements for generating positive effects on the human body; Through field investigation of taste factors, it is found that there is no drinking water source and edible wild fruit, but there are convenient facilities such as rest pavilions, viewing platforms and vending machines; The comprehensive evaluation index of landscape quality of different types of healthy trails ranged from 0.942 0 ~ 6.784 7, and the order is covered space (trees-shrubs-grass) > semi-open space (trees-shrubs-grass or trees-grass) > open space (shrubs-grass or grass). The landscape quality of trees-shrubs-grass was much higher than that of shrubs-grass and pure grass, suggesting a strong recommendation for this type in the future trail design.
