脱硫废弃物对碱化土壤改良效果的评价方法研究

Research on Evaluation Method on the Modified Effect of Desulphurization Gypsum on Alkali Soil

我国碱化土壤改良的面积不断增加,但是缺乏全面评价碱化土壤改良效果的方法。根据国内外研究现状,从脱硫废弃物成分测定、土壤质量评价以及农作物安全性评价3个方面对碱化土壤改良效果进行了分析研究,提出了一种评价脱硫废弃物应用于碱化土壤改良效果的方法体系,以期为碱化土壤改良效果评价的定量化和改良工程的评价提供参考。

For the increasing reclamation area of alkaline soil in China and the lack of a comprehensive evaluation method,an evaluation system was presented which was as an example of the alkaline soil improved by a desulfurization waste.According to the existing research status,improvement effects of alkaline soil were summarized from three aspects of the desulfurization waste composition analysis,evaluation of soil quality and crop safety evaluation,then quantitative evaluation of improvement effect of alkali soil was implemented,in order to provide the reference for agricultural production,improvement of project evaluation and the agricultural environmental protection.
