由于特殊的地理环境及季风环流等因素．使四川盆中老旱区存在着降水偏少和降雨不适时的不利条件，加之风化剥蚀流失使不少旱坡地始终处于幼龄化的发育阶段。而人口增长造成的过度垦殖，又加剧了水土流失的严重程度，因此蓄水、改上、发展电能为基础的节水灌溉技术才是制旱的有效途径。 Due to special geographical environment and monsoon circulation and other factors. As a result, there are some unfavorable conditions when the precipitation is low and the rainfall is not suitable for the dry and arid areas in the Sichuan Basin. In addition, the erosion and erosion loss make many dry slopes always in an early stage of development. However, over-cultivation caused by population growth aggravates the severity of water and soil loss. Therefore, water-saving irrigation technology based on electricity storage and alteration and development of electric energy is an effective way to drought relief.
