砒砂岩与沙复配土体中碳库组分的研究方向

Research Direction of Carbon Pool Components in Soft Rock and Sand Remixed Soil

指出了砒砂岩与沙单独存在时均为自然界两种风化产物,且利用有效性较低,然而利用两者的互补性将其按照一定比例进行复配"成土"可以实现资源的再利用。长期以来通过人为的耕作施肥和再利用,已经使"复配土"质量有了一定的提升,为了长期实现可持续利用及生态效应,介绍了"复配土"的新研究方向。主要从砒砂岩与沙复配的背景、碳库组分和碳库矿化的基础、碳库管理指数和土壤质量的评价等内容进行了阐述,以期为提高"复配土"质量提供参考。

When arsenic-sandstone and sand exist separately,they are two kinds of weathering products in nature,and their utilization efficiency is relatively low.However,the use of their complementarity to"remixed soil"can realize the reuse of resources.The long-term fertilization and reuse of man-made farming has already improved the quality of"remixed soil".In order to achieve sustainable use and ecological effects for a long time,this paper mainly introduces the new research direction of"remixed soil".This paper mainly elaborated the background of soft rock and sand complexed,the basis of carbon pool components and carbon pool mineralization,the carbon pool management index and the evaluation of soil quality,in order to provide reference for improving the quality of"remixed soil".
