黄河后套灌区的土壤盐渍化,已成为发展农业生产的严重障碍。为了解灌区内土壤盐渍化的发生发展规律,因地制宜地采取改良措施,我们选择了杭锦后旗三道桥乡的和平渠(支渠)灌域,做了大比例尺土壤水文地质调查。调查区位于后套灌区的西部,杨家河(干渠)中下游的西侧。灌域内的地形、土质、盐渍化和生产情况,对于后套灌区中西部来说是具有代表性的。
Soil salinization in the irrigation areas after the Yellow River has become a serious obstacle to the development of agricultural production. In order to understand the occurrence and development of soil salinization in the irrigation area and take improvement measures according to local conditions, we chose the Heikou drainage area in Sandaqiao of Hangjinhou Banner and conducted a large-scale survey of soil hydrogeology. The investigation area is located in the western part of Houzao Irrigation District and west of the middle and lower reaches of Yangjiahe (Main Canal). The topography, soil quality, salinization and production in the irrigated area are representative of the central and western China after the irrigated area.
