豫东惠北灌区位于黄河下游南岸的开封、杞县间,北依黄河,南抵惠济河,西与黄汴河毗连,东以圈章河为界,总面积约91.6万亩。历来旱涝盐碱灾害链锁发生,盐碱危害尤甚,轻者作物减产,林木萎黄,重者土地荒芜,林木死亡。我们于1963年通过实地调查,将本区盐渍土的分布特点及其形成的自然因素,作一综合性的论述,根据地区的差异性,提出六个改造利用区,供有关单位参考。
Huibei Irrigation District in East Henan Province is located in the lower reaches of the Yellow River in the southern bank of Kaifeng, Qi County, according to the Yellow River in the north, the Huiji River to the west, the West and the Huangpi River adjoining the East Circle Capital River for a community with a total area of about 91.6 hectares. Salinization has always been a chain of calamities and disasters, salt and alkali hazards particularly, the light crop production, forest chlorosis, severe land shortage, forest deaths. In 1963, we conducted a survey on the spot to make a comprehensive discussion of the distribution characteristics of saline soil and the natural factors that formed in this area. Based on the regional differences, we proposed six transformation and utilization areas for the reference of relevant units.
