近代黄河三角洲的滨海盐渍土及其开发利用

Seaside Saline Soil of Neo-Delta of Yellow River and its Exploita tion and Utilization

近代黄河三角洲属近百年来的新成陆地，面积约６７．５×１０４ｈｍ２，大部分为滨海氯化物盐渍土，其中滨海盐土的面积约占６３．７％，土壤盐渍化危害 十分严重．盐渍土资源合理开发利用的途径是实施区域性的分区划类，建成相应的小麦、水 稻、棉花、畜产品及滩涂养殖业等不同类型的生产基地；大力增加土地投入，改善农业装备 ；开展必要的基础与应用科学研究，发展可持续农业．

Neo-Delta of Yellow River is land come into being within recent several hundreds years. The area is about 67.5×104hm2. The soil was seaside chloride saline soil. The seaside saline soil is about 63.7% in area and the salination is serious. Regional subareas and classifications are the reasonable routines for exploitation and utilization of saline soil re- sources. Corresponding production base, such as wheat, rice, cotton, livestock and seaside aquiculture, should be estab- lished. Land input and agricultural equipments should be improved. It's necessary to study of basic and applied science, and develop the sustain able agriculture.
