Historical Evolution The historical evolution of Huizhou Weir dates back to the second year of Xianhe in the Eastern Jin Dynasty (AD 327), and it has a history of nearly 1700 years. The construction of these weirs not only reflects the wisdom of the ancient Huizhou people in utilizing water resources but also witnesses the development of agricultural civilization in the Huizhou region. The construction and development of Huizhou Weir are closely linked to the socioeconomic fabric of the Huizhou area. As recorded in "Huizhou Water Conservancy Chronicles, " there are more than 20 ancient weirs over 500 years old, one terraced field from the Ming Dynasty, and more than 10 ancient village irrigation systems in Huizhou District. These water conservancy projects provided a solid material foundation for the development of Huizhou's socioeconomic culture and are also representative regional cultural water conservancy heritages in the history of ancient Chinese water conservancy[1]. 1.2. Geographic and Structural Features The main section of Huizhou Weir is located within the jurisdiction of Xixinan Town in Huizhou District, with two reservoirs and north-south main canals built upstream, and four water channels, as well as two small reservoirs, downstream. These directly irrigate nearly ten thousand acres of fertile fields along both banks of the Fengle River in the central and eastern parts of the town. The geographical distribution of Huizhou Weir fully reflects the geographical environmental characteristics of the Huizhou area, which is known as "seven parts mountain, one part water, one part field, one part roads, and manors. " The construction methods and irrigation principles of Huizhou Weir are rich in the characteristics of the mountainous area of Huizhou. Initially, the construction of the weirs was very simple. A relatively narrow section of the river was chosen, and pine logs were hammered into the soil as the base, with osiers and bamboo strips as the weft, covered with sand, stones, and weeds to retain water. Later on, mountain stones were gradually used to build the weirs, and flood discharge outlets were added, with water levels adjustable as needed. This structural design not only saved labor but also was not limited by the distance of the water source, reflecting the Huizhou people's profound understanding and utilization of the natural environment. 2. The Socioeconomic Value of Huizhou Weir 2.1. The Cornerstone of Agricultural Development As the cornerstone of agricultural development, the socioeconomic value of Huizhou Weir is primarily reflected in agricultural production. The Huizhou region, with its many mountains and limited arable land, has rivers that mostly meander through the mountains, making artificial water extraction difficult. The construction of Huizhou Weir, by utilizing the natural drop to impound water sources and regulate water levels, provided a moderate amount of water for local agricultural activities. Huizhou Weir played a crucial role in water resource supply. According to the "Huizhou Water Conservancy Chronicles, " there are more than 20 ancient weirs in Huizhou District with a history of over 500 years, which directly irrigate nearly ten thousand acres of fertile fields, providing a stable source of water for agricultural production in the Huizhou area[1]. In Huizhou, where mountains are abundant and land is scarce, rivers wind through the mountains with significant drops, making manual water extraction time-consuming and labor-intensive. The construction of weirs allowed river water to flow into the fields through canals, saving time and effort and improving agricultural production efficiency. Statistics show that the irrigation system of Huizhou Weir covers most of the farmland in Huizhou District, ensuring the stability of local food production, with a contribution rate to Huizhou's agricultural economy of over 60%. 2.2. Improvement of Water Conservancy Management System The water conservancy management system of Huizhou Weir is another important reflection of its socioeconomic value. The management system of Huizhou Weir demonstrates the high wisdom and profound understanding of water resource management by the people of Huizhou. The weir irrigation system has the advantages of saving labor and not being limited by the distance of the water source[2]. This management system is not only efficient but also capable of adjusting water levels according to actual needs, achieving rational allocation and utilization of water resources. The water conservancy management system of Huizhou Weir also includes the maintenance and management of water resources. According to the "Huizhou Water Conservancy Chronicles, " the ancestors of Huizhou "built weirs to block water, dug ponds to store water, and repaired canals to divert water, " forming a complete water conservancy project system. This system includes not only the weirs themselves but also several components such as mountain ponds, water mouths, water streets, and wells, constituting an irrigation project system that conforms to nature and is exquisitely perfect. The existence of this water conservancy management system allows Huizhou to maximize agricultural benefits under limited water resources while protecting the local ecological environment. The water conservancy management system of Huizhou Weir is also reflected in its collective management of water resources. According to the "Huizhou Water Conservancy Chronicles, " many weirs in Huizhou were built with the initiative of the prefecture and county governments, with the public contributing labor and effort, and some were funded by wealthy merchants and local gentry or built by private individuals[1]. This collective management model not only improves the construction efficiency of water conservancy projects but also enhances the community's cohesion and shared responsibility for water resources. Through this model, the water conservancy management system of Huizhou Weir continues to operate, providing a solid foundation for the socioeconomic development of the Huizhou area. 2.3. Impact on Social Structure The construction and maintenance of Huizhou Weir deeply reflect the characteristics of the social structure in the Huizhou area. In Huizhou, the construction of weirs often required the mobilization of the entire community's efforts, a collective action that reflects the organizational structure of Huizhou society based on clans and villages. According to the "Huizhou Water Conservancy Chronicles, " the ancestors of Huizhou "built weirs to block water, dug ponds to store water, and repaired canals to divert water. " The construction of these water conservancy projects required a significant amount of labor and complex organizational coordination, all of which depended on the close cooperation of clans and villages[1]. The existence of Huizhou Weir also promoted the formation of social stratification and occupational division. The construction and maintenance of weirs required professional craftsmen and skills, which were often passed down through generations, forming a unique professional group. At the same time, the management of weirs also required certain knowledge and skills, and these management personnel often enjoyed a higher status in local society. The formation of this social stratification and occupational division is an important sign of the development of Huizhou's social structure. In addition, the management and maintenance of Huizhou Weir also reflect the collective management of water resources in Huizhou society. According to the "Huizhou Water Conservancy Chronicles, " many weirs in Huizhou were built with the initiative of the prefecture and county governments, with the public contributing labor and effort, and some were funded by wealthy merchants and local gentry or built by private individuals. This collective management model not only improves the construction efficiency of water conservancy projects but also enhances the community's cohesion and shared responsibility for water resources. Through this model, the water conservancy management system of Huizhou Weir continues to operate, providing a solid foundation for the socioeconomic development of the Huizhou area. 2.4. Promotion of Economic Activities The promotion of local economic activities by Huizhou Weir is multifaceted. Firstly, the construction of the weir provided a substantial number of employment opportunities for the local area. According to the "Huizhou Water Conservancy Chronicles, " a significant labor force was required when the ancestors of Huizhou built the weirs, often drawn from local farmers and craftsmen. The construction and maintenance of the weirs not only provided additional income for these farmers and craftsmen but also stimulated the development of the local economy. Secondly, the construction of Huizhou Weir has promoted the development of local agriculture. The presence of the weir ensures a stable source of irrigation water for the farmlands in the Huizhou area, which is crucial for agricultural production[1]. As recorded in the "Huizhou Water Conservancy Chronicles, " the irrigation system of Huizhou Weir covers most of the farmland in Huizhou District, ensuring the stability of local food production. This stable agricultural production provides a solid material foundation for the local economy. Lastly, the construction of Huizhou Weir has also promoted the development of local commerce and handicrafts. The construction and maintenance of the weir require a large amount of building materials and tools, which often need to be purchased or customized externally. This demand has stimulated the development of local commerce and handicrafts, injecting vitality into the local economy[1]. 2.5. Catalyst for Modern Tourism With the deepening understanding of weirs, their cultural value and historical significance have gained broader recognition. Huizhou Weir, with its unique historical charm and era style, attracts a large number of tourists and photography enthusiasts, becoming an important force in promoting the development of local tourism. According to statistics from the tourism department, in recent years, Huizhou District has restored the ancient water transport functions of Huizhou Weir on the Fengle River, "stringing pearls into a chain" by connecting the cultural relics and natural landscapes along the line. Ancient irrigation water conservancy projects such as Lei Weir and Lu Weir have attracted numerous tourists to view and photograph, becoming popular check-in spots, reflecting the new vitality of irrigation heritage in inheritance and protection. Statistics show that the tourism revenue in Huizhou District has increased by 150% in the past five years, with tourism routes centered on Huizhou Weir contributing nearly 30% of the tourism revenue. These ancient irrigation water conservancy projects, such as Lei Weir and Lu Weir, have not only become popular check-in spots but also important windows for displaying Huizhou culture. Tourists can not only appreciate the spectacular scenes of ancient water conservancy projects but also gain a deep understanding of the history, culture, and agricultural civilization of the Huizhou area. In addition, the tourism development of Huizhou Weir has also driven the economic development of surrounding areas. Data from the tourism department shows that the income from related industries such as catering, accommodation, and transportation around Huizhou Weir has increased by nearly 50%. The development of these industries not only provides employment opportunities for local residents but also promotes the diversified development of the local economy. 2.6.
