Abstract

In the practice of water control in the past dynasties in China, plain systemic thought runs through it. In Gaoyou, Jiangsu Province, the Li Canal connects Gaoyou Lake and Gaoyou Irrigation District through hydraulic facilities such as gates and dams on the east and west embankments. It realizes the deployment of water between "Lake-Canal-Irrigation District" system and takes into account irrigation and water transport. "Lake-Canal-Irrigation District" system is an open and complex system, from water storage, water transfer, water transportation, water distribution to irrigation, it is an organic whole coordinated operation, achieving dynamic balance. The "Lake-Canal-Irrigation District" system is connected, which promotes regional biodiversity and interprets the concept of sustainable development of "the harmony between man and nature". The "Lake-Canal-Irrigation District" system solves the imbalance in the spatial and temporal distribution of water resources and improves the utilization efficiency of water resources. The systematic ancient water control projects have been enduring for a long time. Although they have evolved and developed, the basic layout structure and the principles of organization have been implemented throughout.
