萨迦古代灌溉系统的工程技术特征及现代启示OA

The ancient irrigation system of Sakya is a representative water conservancy engineering heritage in the high-cold environment of the Qinghai-Xizang Plateau.This paper combines historical literature and engineering analysis methods to systematically analyze its composition structure,operation mechanism,and comprehensive benefits.Research shows that this irrigation system has established a complete technical system through channel network,reservoir group,and gate control:the channels adopt a three-level layout and apply local anti-seepage technology,and the hydraulic structure design is scientific and reasonable,The reservoir takes advantage of the strong sunlight conditions on the plateau to raise the water temperature and enhances the anti-seepage performance with the help of a composite structure.At the management level,with the Chongqu River water gate as the core and combined with the three-level co-governance model led by the community,seasonal regulation of water resources has been achieved.This system not only effectively enhances agricultural productivity and promotes the development of settlements,but also forms an adaptive governance model that integrates technology,system,and culture.The ecological wisdom and governance experience it contains have a significant reference value for modern high-altitude areas in addressing water resource challenges.
