黄淮海平原盐碱地治理与农业生态环境变迁——以河北省黑龙港及运东地区为例

The Control of Saline-alkali Field in Huanghuai River Plain and the Transition of Agro-ecological Environment——The Case of Heilonggang and the Far East of Yunhe River in Hebei Province

新中国成立后,河北省黑龙港及运东地区,在调查分析盐碱地形成发展规律的基础上,开展了大规模的治碱活动,使该区发生了深刻变化。由低产到高产,由吃返销粮到为国家提供商品粮,进而成为河北省的棉粮基地,农业生产的重点开发区。其成功经验,推动了黄淮海平原盐碱地综合治理,为扭转我国南粮北调和长期粮食短缺做出了贡献,为世界各国治碱防灾提供了借鉴。

Since the founding of New China,the large-scale activities in controlling saline-alkali field in Heilonggang and the East of Yunhe River has taken place,which brought profound changes to the area based on the investigation and analysis on the formation and development rule.The area becomes a main base to produce grain and cotton,and the major area for agricultural product after experiencing lower productivity to higher productivity,from receiving state-purchased grain to offering grain for the country.The successful experience facilitates the comprehensive control of saline-alkali in Huanghuai River Plain and contributes to the grain redistribution between the south and the north in China and to the solution for the problem of grain shortage.It also provides a good example for the world to control natural disasters and saline-alkali problem.
