摘　　要：为了探讨"以渔治碱"模式在盐碱地治理方面的成效及其作用机制,以甘肃省景泰县盐碱地为试验区,采用水产养殖治碱技术比较了砂型土壤和壤性土壤的治碱效果。通过定期监测和分析养鱼前后不同类型土壤和水体中水质参数的变化,研究水产养殖对该地区盐碱迁移的影响。结果表明,采用水产养殖模式在一定程度上可改良盐碱区的土壤环境,沙型土壤的盐碱治理效果优于壤性土壤,养殖期间产生的氨氮也并未呈现出一直升高的趋势,未对当地造成二次污染。本研究结果为"以渔治碱"模式在西北地区的应用和推广提供一定的理论依据及技术支撑。To study the effect and mechanism of"using aquaculture to curb alkali saline-area"model on the saline-alkali land, the saline-alkali land in Jingtai County was used as test field, the solodization effect of aquaculture technology on sandy saline-alkali soil and loam saline-alkali soil was compared. The effects of aquaculture on saline and alkali migration were studied by regularly monitoring and analyzing the changes of water quality parameters in different types of soil and water before and after fish culture. The results showed that the aquaculture model could improve the soil environment of saline and alkaline areas to some extent, and the control effect on sandy soil was better than that on loam soil. In addition, the ammonia nitrogen produced during the cultivation did not show an upward trend, which indicated that it did not cause secondary pollution to the local area. The results of this study provided theoretical and technical support for the application and promotion of"using aquaculture to curb alkali saline-area"model in northwest China.
