粉煤灰碱法提铝的副产物-蛋白石(SiO_(2)·nH_(2)O,非晶质二氧化硅)具有很强的吸附性,是土壤中的次生/黏土矿物。将蛋白石与沙粒复配形成团聚体应用于沙漠化土壤修复,是一种前景广阔的大规模生态化处置方式。然而,由于无机矿物质的缺乏,该团聚体与自然土壤团聚体仍有差距。本文通过短期土培实验,研究了石灰石(CaCO_(3))、脱硫石膏(CaSO_(4)·2H_(2)O)、磷酸钙(Ca_(3)(PO_(4))_(2))、赤铁矿(Fe_(2)O_(3))、三水铝石(Al(OH)_(3))等无机矿物改良剂对团聚体形成、稳定以及孔隙特征的影响,并阐述了其内在的吸附机理。结果表明,五种改良剂中,只有石膏可有效降低团聚体的pH,且石膏对提升团聚体的保水效果最为显著,但石膏会增大电导率。改良剂均能促进团聚体的形成,提高机械稳定性,石膏、CaCO_(3)、Fe_(2)O_(3)有利于提高团聚体的水稳性。XRD/SEM/FT-IR/XPS等分析表明,无机矿物与沙子/蛋白石发生吸附作用,团聚体表面形成了有利于团聚体生成的无机矿物界面层。与CK相比,改良后的大团聚体(>0.25 mm)以孔径15 nm介孔的数量。总之,作为土壤“骨架”的无机矿物有效改善了蛋白石/沙粒团聚体的物理结构,加速了团聚体的形成。因此,脱硫石膏优化了大聚集体的形成和稳定性。经脱硫石膏改良的团聚体可作为类土壤基质,加速退化的沙漠化土壤的生态重建。

According to the target threat assessment in battlefield, a threat assessment method based on a combination of membership cloud and particle swarm optimization was proposed. This method can on one hand adjust weights automatically according to the overall distribution of the indexes’ value by utilizing particle swarm to optimize the weight, and on the other hand, establish a cloud model based on threat sequencing, as to make the assessment process fully take the fuzziness and randomness of threat information into account. Finally, a three-layer index system is built to test the method and the validity and rationality is verified.
