通过封山育林、种草植树、林草截雨、土壤储水,因地制宜修建梯田,以山坡上众多的渗水为灌溉水源,以土壤孔隙、岩石裂隙和田边微型毛沟输水,构成了紫鹊界梯田漫山遍坡的灌溉系统。总结了紫鹊界梯田纳雨储水原理,分别为特有的山峰气候和地形雨为梯田补充水源、植被接纳雨水和土壤储水形成天然水库、土壤中的输水网络、山坡细沟与田间毛渠结合形成田间灌溉系统、精耕细作与利用田间蓄水以及合理调度取水用水等。还总结了紫鹊界梯田封山育林、精筑田埂和科学设置泄洪沟等水土保持方法。 Terraced fields were built by closed hillsides afforestation, planting trees and grasses, cutting grass and trees, storing soil and water, and constructing terraces according to local conditions. With many seepage water on hillsides as irrigation water source, water from soil pores, rock fissures, All over the slope of the irrigation system. Summed up the magpie terraces nanjiang water storage principle, respectively, for the unique peak climate and terrain rain terraced fields to add water, vegetation to receive rain and soil water storage to form a natural reservoir, the soil water network, hillside rill and field hair Drainage combined to form a field irrigation system, intensive and make use of field water storage and reasonable water intake and so on. Also summed up the purple magpie terraces closing hillsides to facilitate afforestation, fine Zhuo Tian Jian and set flood discharge and other water and soil conservation methods.
