黄河下游两岸的泛滥平原区(黄、淮、海平原)耕地面积的二亿四千万亩,是我国主要的早作农业区。发展该地区的农业生产对于落实毛主席“深挖洞,广积粮,不称霸”的指示,“扭转南粮北调”有十分重要意义。干旱、内涝、盐碱(旱、涝、碱)是限制平原区农业生产发展的主要自然因素。旱涝交错,涝碱相随,旱、涝、碱灾害经常发生,使农业生产很不稳定。
The floodplain area (Yellow, Huai and Hai Plain) of 240 million mu of arable land along both sides of the lower Yellow River is China’s major early agricultural area. The development of agricultural production in the region is of great significance to the implementation of Chairman Mao’s “deep digging, extensive grain rationing and no hegemony” directive and “reversing the south grain north transfer”. Droughts, waterlogging, salinization (drought, waterlogging and alkali) are the main natural factors that limit the development of agricultural production in the plain areas. Droughts and floods staggered, waterlogging and alkali, drought, waterlogging, alkali disasters often occur, so that agricultural production is very unstable.
