Vernacular architecture provides valuable insights into bioclimatic design, an integral part of the architectural design process. This study aims to investigate the bioclimatic design strategies used in vernacular architecture in southeastern China, with the goal of inspiring energy-efficient restoration and contemporary architectural design. Initially, the Mahoney Table was used to identify a priori bioclimatic design strategies, serving as a reference for the field survey conducted in three distinct landscape regions. Subsequently, a field survey was conducted to identify and summarize the characteristics of 907 vernacular buildings across 63 settlements, focusing on their bioclimatic potential and categorizing them into five aspects of bioclimatic strategies. The results revealed that bioclimatic design strategies vary in response to local conditions, deviating from the recommendations of the Mahoney Table. This underscores the significance of empirical studies on vernacular bioclimatic design strategies. The findings from this study have practical implications for guiding regional building practices in areas with similar climates and landscapes.

Traditional villages are the common historical and cultural heritage of all mankind. With the intensification of urbanization, the continuation of traditional villages and the inheritance of historical and cultural heritage are facing risks. The research on the driving factors affecting the spatial distribution characteristics, heterogeneity and human land interaction of traditional villages provides a new idea for the protection of traditional villages. This study takes 137 traditional villages in Puxian area, a typical cultural area in the southeast coast, as the research object, analyzes the spatial distribution pattern of traditional villages by using spatial analysis method, and selects 13 factors to analyze the main driving forces and interaction mechanisms through geographical detectors. The results show that: (1) Puxian traditional villages are clustered and distributed, and the distribution among counties is uneven, mainly in the state of "one cluster and many scattered points" with more coastal areas and less mountainous areas. (2) Puxian traditional villages are mainly affected by many factors such as nature, space, society and culture. They are more densely distributed in areas with rich cultural heritage, fertile land, flat terrain, suitable climate, close to water systems, developed transportation, backward economy and dense population. (3) Cultural factors are the primary factors affecting the spatial distribution of traditional villages, the order of driving factors’ explanatory power is: intangible cultural heritage (0.5160) > protected cultural relic units (0.3591) > distance from railway (0.3255) > night light remote sensing (0.3179) > elevation (0.3012) > population density (0.2671) > slope (0.2032) > soil type (0.1804) > precipitation (0.1750) > temperature (0.1744) > land use (0.1492) > distance from river (0.0691)>distance from highway (0.0530). The interaction of intangible cultural heritage, protected cultural relic units and distance from the railway is the dominant factor for the spatial differentiation of traditional villages. Among them, the interaction of intangible cultural heritage∩distance from the railway is the strongest, and the q-value is 0.79, which proves that the interpretation ability of the two factor model is much higher than that of the single factor model. The results of this study reflect that traditional villages and nature, space, society and culture are interdependent, so the protection of traditional villages should be adapted to local conditions.

Urban community parks have significant benefits for city residents, both physical and spiritual. This is especially true in developing countries, such as China. The purpose of our study is to describe the current situation of the community parks in five main districts of Jinan City while recognizing features of the community parks that influence usage patterns. Our study also means to determine the desired improvements of visitors that promote access to and use of community parks on the basis of the Chinese context. We conducted a survey among 542 community park visitors and obtained valid responses. The findings of respondents show that community parks are mostly used by people over 55 years (34.7%) and children under 10 years (23.6%). The main motives for using community parks are for exercise (24.2%) and to socialize with others (21.6%). The majority of respondents (65.7%) rated the community park as satisfactory and considered only a few improvements needed. Regarding the desired improvements, numerous respondents mentioned adding more physical training facilities (13.3%) and activity areas (7.6%), as well as emergency call buttons in areas frequented by children and older people (7.6%). Furthermore, most of the respondents (79.9%) indicated that they would like to use the community parks more frequently if there is additional progress to make the parks more attractive, cleaner, and friendlier. These results can help park designers, government agencies, and community groups to provide the planning and design strategies for community parks to promote their upgrading in China.

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.

Casearia glomerata Roxb. is classified in Salicaceae and has a high economic value. Herein, we report the complete chloroplast (cp) genome of C. glomerata using Illumina sequence data. The cp genome is 156,809 bp in length and contains a large single-copy (LSC) region of 84,888 bp and a small single-copy (SSC) region of 17,039 bp separated by two inverted repeat (IR) regions of 27,441 bp each. It contained a total of 123 genes, with an overall GC content of 36.81%. The phylogenetic analysis showed that C. glomerata is closely related to Casearia velutina. This study provides important sequence information for species identification and its phylogenetic relationship in the Salicaceae
