To better understand the mechanism of Gravity Irrigation and water resource allocation and provide the background for future systematic managements within the Ziquejie Terrace, large amounts of observational data were collected and processed. The nonlinear autonomic regulation theory and the groundwater reservoir on the same slope position theory have been applied to model the water supply-demand balance model for groundwater irrigation.
Based on the formation of the primitive gravity irrigation system of Ziquejie Terrace and comprehensive consideration of the local background of history and culture, a reasonable division of functional zones of the scenic spot has been proposed: the core scenic zones, the protection zones and buffering zones (i.e., protection through coordination).
Based on the result of functional zoning, the key factors that influence the primitive gravity irrigation system have been analyzed. In consultation processes of local farmers, researchers and the local government the related measures have been proposed and targets identified. The core zone should remain its primitive landscape without constructions. All protection measures must be non-engineering and adapted to the natural environment. Any construction that interrupts the overall landscape of the terrace should be reformed or dismantled. In protection zones, any facility that is irrelevant to the protection, management or development of the terrace should be forbidden. In buffering zones, any projects that have the potentials to damage the terrace environment should be prohibited.
