From the perspective of landscape environment and human health, this study introduces the concept of soundscape from soundscape ecology. Through two experiments evaluating the restorative properties of soundscapes, it analyzes and compares the differences in restorative benefits among various sounds in urban green spaces. The study further explores the effects of single soundscapes and combined soundscape types on environmental restorative benefits and provides recommendations for creating restorative soundscapes in urban green spaces. The main findings of this study are as follows: (1) Sound types significantly influence soundscape restorative benefits, with notable interactions observed among three single soundscape categories. Significant differences were also found in the restorative effects of different combined soundscapes. (2) The most restorative sounds for anthropogenic, biophonic, and geophonic soundscapes are light background music (1.4193), bird sounds (1.9890), and flowing water sounds (1.2691), respectively. The least restorative sounds are vehicle noise (−2.6210), conversation sounds (−0.8788), and thunder sounds (−0.7840). (3) Significant differences exist between the restorative effects of single and multi-level combined soundscapes. Except for bird sounds, the general restorative pattern is as follows: two-level combined soundscapes > three-level combined soundscapes > single soundscapes.

From the color geography perspective, a field investigation was conducted in the Minjiang River Basin, constructing a color index system of traditional villages. In Python, a random forest model was constructed to screen out important color indexes for traditional village color classification and explore its influence mechanism. Among eight color indexes, the important indexes are wall form and building face form, accounting for 30.50% and 19.40%, respectively. Based on this, the basin was divided into four color zones presenting color characteristics and eight color subzones presenting architectural features. The influence mechanism concerns dialect divisions that have shaped traditional villages of different color types, and the interconnection of water systems has promoted the connections among them. The application of traditional village colors in the new urban and rural planning can enhance local characteristics. Integrating the color resources of traditional villages contributes to the regional protection of culture and economic development.

The colors of traditional dwellings are an extremely intuitive manifestation of regional culture and an important reference for guiding rural housing. This study takes the Gutian district as the research region and explores the internal influence mechanism of the “color perception–preference–supportive behavior” of the indigenous residents towards traditional dwellings, specifically rammed earth dwellings. After constructing a structural equation model, the results were as follows: (1) The color perception of the indigenous residents towards traditional dwellings has two dimensions: distinctiveness and rootedness. (2) The color perception of the indigenous residents towards traditional dwellings can significantly enhance their color preference, but the two dimensions of color perception have different effects on color preference. (3) Color perception has a direct impact on color supportive behavior, mainly reflected in the dimension of the perception of distinctiveness. On the other hand, the mediating role of color preference has a positive impact on color—supportive behavior, mainly reflected in the dimension of the perception of rootedness. This study constructs a positive—cycle model that goes from the strengthening of color perception to the promotion of color preference and finally to the enhancement of color supportive behavior. The aim is to deeply analyze the multiple values contained in the colors of traditional dwellings, which not only demonstrate regional characteristics but also closely meet the emotional needs of the indigenous residents and have broad application potential in rural housing and cultural inheritance significance.
