摘要： 在改良盐碱地的措施中，60年代在山东禹城和河南封丘采用“井灌井排”的方法，70年代在我国北方部分地区采用“抽咸换淡”的方法。在上述两种方法的基础上，80年代末期，根据禹城市北丘洼的具体条件，采用了“强排强灌”的方法改良重盐碱地。后一种改良方法的特点是周期短，效果显着，当年改良当年可以有收益。改良后的土地人工生态系统的稳定性可以通过一年四季种植作物、灌溉、施肥和中耕松土等农业措施，长期维持。

Abstract: Well irrigation and well drainage" was adopted to ameliorate saline-alkaline land in the 1960’s in Feng Qiu and Yucheng, and "pumping saline-water and suppling fresh water" was used to improve saline-alkaline land in the 1960’s in the northern part of China.On the bases of the specific conditions in Bei Qiu in Yucheng City, we adopted a method of intensive pumping and irrigation to ameliorate saline-alkaline land. The improvement is distinct, and the treatment period is shorter.After intensive pumping and irrigation, the ecological conditions can be long maintained by spreading manure, intertilling and loosening the soil, covering with crops at all seasons, salt content in the cultivated layer is less than 0. 2%, and crops grow very well for 4 years.It is clear that irrigation can leach salt of soil, spreading manure and nitertilling-loosenning the soil can improve root condition. Pumping saline water and Levelling of land can strengthen the improving effect.

Key words: intensive pumping and irrigation, desalination, artificail ecological system stability
