发展高扬程灌溉绿洲农业是宁夏中部干旱带生态建设与经济发展的根本出路。宁夏大型扬水工程从1975年建设以来,经过30多年的开发建设,全区共有各类扬水工程763处,泵站近1400座,其中大中型扬水13处,总装机容量42.29万千瓦,开发土地面积10.39万公顷,发展灌溉面积7.23万公顷。由于扬黄灌区部分土壤母质含盐量较高、土体中不透水层的存在以及独特的地质地貌条件,特别是水资源的不合理利用,在种植利用时间较短的情况下,土地次生盐渍化面积越来越大,目前全灌区土壤盐 Developing High-elevation Irrigation Oasis Agriculture is the Fundamental Way Out for the Ecological Construction and Economic Development of Arid Zone in Central Ningxia. Since its construction in 1975, after more than 30 years of development and construction, Ningxia large-scale pumping project has a total of 763 pumping stations of various types and nearly 1400 pumping stations, of which 13 are large and medium-sized pumping stations with a total installed capacity of 422,900 kilowatts. The land area for development 103,900 hectares, the development of irrigation area 72,300 hectares. Due to the high salinity of some soil parent materials, the impermeable layer in the soil and the unique geological and geomorphological conditions, especially the irrational use of water resources in the Yellow River Irrigation Area, in the case of short planting and utilization time, The area of ​​salinization is getting larger and larger. At present, soil salt in the whole irrigation area
