Throughout the long history of ancient China, agriculture has always been an important pillar of economic and social development. In the process of the development of agricultural civilization, water conservancy undoubtedly played a key role. Especially in the important historical stage of the Eastern Jin Dynasty, with the improvement of the level of productivity and the increasing pressure of population growth, the demand for farmland irrigation is also increasing.
In this context, the water conservancy projects in the Eastern Jin Dynasty have been vigorously developed and improved, and have had a far-reaching impact on improving agricultural production efficiency and ensuring food supply. One of the most representative is the application and promotion of the new irrigation tool of the water wheel. The waterwheel is a kind of equipment that uses the power of water flow to irrigate farmland, and its emergence greatly improves the efficiency and accuracy of farmland irrigation. Moreover, because the waterwheel can be powered by natural water sources such as rivers or lakes, it has the advantage of saving manpower and material resources, and is more able to adapt to the irrigation needs of large-scale fields.
During the Eastern Jin Dynasty, many other water conservancy facilities and technologies appeared, such as embankments, canals, irrigation canals, etc., which provided a more comprehensive and reliable guarantee for farmland irrigation. At the same time, in order to effectively manage and maintain these water conservancy facilities, the government has also set up a number of special agencies, such as the "Water Resources Department" and the "Tado Office," which are responsible for supervising and guiding water conservancy work in various localities. Through the efforts of science and technology and system, the irrigation of farmland in the Eastern Jin Dynasty has achieved remarkable results, which has played a positive role in promoting the social and economic development at that time, stabilizing the state power and meeting the people's living needs.
Although the farmland irrigation technology and management level at that time were quite advanced, due to various reasons (such as natural disasters, war damage, etc.), these achievements have not been fully inherited and developed. This has also become a regret for the water conservancy cause in ancient China, and at the same time, it has also left us with a valuable lesson today - only by continuous exploration and innovation can we maintain a leading position in farmland irrigation technology to better serve modern agricultural production and the needs of the people.
