黄河内蒙后套冲积平原,北依狼山,南临黄河,西起乌兰布和沙漠之边缘,东抵乌拉山之西端,总面积约1280万亩,呈扇面形展布,是我国著名的大型灌区之一。后套灌区,在全面发展农林牧付渔业等方面,有着极大的潜力。但土壤盐碱化的存在和发展,却成为发挥这种潜力的巨大障碍。在全面地进行土壤改良分区和综合治理过程中,虽然已经做了大量的有效的工作,但仍有许多悬而未决的问题,必须从时间上和空间上对水盐运行规律搞清之后,才能得以妥善解决.笔者综合前人的调查研究成果、群众的经验,和自己的工作实践,从后套灌区的地
The Inner Mongolia Autonomous Region follows the alluvial plain in the north, followed by the Langshan in the north, the Yellow River in the south, the edge of the Ulan Buh Desert in the west, and the western end of the Wulashan in the east. The total area is about 12.8 million mu and is fan-shaped spreading. One of the major irrigation districts. After the irrigation area, in the full development of agriculture, forestry, animal husbandry and fishery, etc., has great potential. However, the existence and development of soil salinization have become a huge obstacle to realizing this potential. In a comprehensive process of soil improvement zoning and integrated management, although a great deal of effective work has been done, there are still many outstanding issues that must be solved in time and space to clarify the operation rules of water and salt Solve.The author combines the results of previous research, the masses of the experience, and their own work practices, from the area after the set of irrigation
