The neurodivergent blood donor: Fairness, discrimination, screening, and behavior.

Rural settlements emerged as a form of human habitation following the transition from prehistoric hunting-gathering societies to agrarian civilization, serving as the loci where agricultural producers congregated, labored, and thrived. In China, rural settlements cover an area exceeding 2 million km², constituting an integral component of the national territory. Cultural landscapes represent the outcomes of human creative modification of the natural environment in response to societal needs, embodying the cultural characteristics and physiognomy of a given region. Traditional settlements offer a crucial entry point for the study of cultural landscapes, among which traditional villages—condensing the wisdom and practical achievements of successive generations of working people—are the most direct and representative, possessing high historical, cultural, and artistic value. In 2012, the release of the first batch of China’s Traditional Village List marked the official launch of state‑led conservation efforts. To date, 8155 villages have been included in the list and placed under legal protection. However, amid rapid urbanization, numerous villages that embody significant traditional historical and cultural values are gradually declining or even facing the risk of disappearance. Once a traditional village is damaged, it may lead to the loss of core cultural assets and undermine the preservation and revitalization of cultural heritage. The vulnerability of these villages has become an internationally recognized concern. How to rationally protect and develop traditional villages in the context of modernization has thus emerged as an urgent challenge, particularly for developing countries. Faced with the reality of a large number and wide variety of traditional villages, conservation efforts targeting individual villages in isolation tend to disperse resources and, due to a lack of overall coordination, often lead to haphazard development. Consequently, research on the concentrated and contiguous protection and development of traditional villages has become a hot topic in recent years. Scholars have proposed conservation approaches such as cultural heritage clusters and regionalization, articulating the concept of zone‑based (or cluster‑based) protection and focusing on protection methods and models to promote co‑construction, sharing, and diversified revitalization of contiguous zones, thereby forming a systematic and organic entity. This direction aligns well with the principles of integrated conservation and sustainable use emphasized in cultural landscape heritage. As a distinctive heritage type and conservation concept, the cultural landscape offers inherent advantages for traditional village research. In terms of the composition of cultural landscapes, Kang, N. and Liu, C. classified the cultural landscape of traditional villages in Anyi County into four aspects: natural, agricultural, living, and humanistic based on human perception. Wang, J. and Long, B. suggested that the cultural landscape comprises two categories of landscape elements: material culture and social culture. Zheng, W. et al. further subdivided it into two major categories (material and intangible) and 15 subcategories, including village morphology, building materials, language, and festivals. Hu, Z. et al., from the perspective of settlement landscape genes, divided it into four parts: architecture, culture, environment, and layout. The above studies have laid an important foundation for the identification and classification of traditional village cultural landscapes. However, when these classification frameworks are directly applied to a study area like the Min River Basin, which is characterized by “numerous mountains, dense rivers and cultural diversity”, they often encounter many challenges. Based on this critical assessment, this study did not adopt any single model as a ready-made template. Instead, we regarded these previous classifications as a collection of candidate indicators, and then adjusted their categories, levels and identification criteria according to the unique geographical and cultural features of the basin.
