Although there were different influences on these soil enzymes for different metals, it was difficult to find a special soil enzyme to index a single heavy metal pollution in soil. Also, little was known about the interwork of heavey metals, soil enzymes and soil conditions. Therefore, lots of research will be needed to accomplish the foundation of enzymes indexes for assessing heavy metals pollution in soil.

虽然不同重金属元素对土壤酶活性的影响差异较大，但很难用某一专有土壤酶来反映特定重金属的污染，而且关于酶系统与重金属以及土壤自身和外界环境因素的相互作用机制尚不清楚，所以土壤重金属酶学指标的建立还需做大量的研究工作。

系统划分了大孔隙类型；描述了大孔隙形态；通过对土壤切片图像数字化处理和分析，获得了描述大孔隙特征的两个基本指标：大孔隙度和周长，并对大孔隙进行了定量化地描述；比较了各土类之间大孔隙的形态差异，从土壤发生学的角度对其原因进行了分析；研究了地带性差异、土壤层次和土地利用方式对大孔隙特征的影响；阐明了小尺度范围大孔隙的空间分布特征；结合Br〓标记优先水流穿透曲线分析了大孔隙的连通性和弯曲性，探讨大孔隙形态指标评价大孔隙优先水流作用强弱的可行性。

The chemistry behavior research of wollastonite indicated that the silicon-potassium fertilizer has a chemical active in organic acid.The factors affecting manurial effect of silicon-potassium fertilizer are not only soil pH and desilicification,but also content and type of organ in the soil.Wollastonite chemistry behavior indicates that silicic acid can be dissolved out from silicon-potassium fertilizer in chlorhydric acid solution if pH of solution is not smaller than 2. The drop of apparent density,increase of DBP sorptive rate and specific surface for leavings indicate that hydrated silicon oxide is polyporous,and those mineralogic feature presignify that silicon-potassium fertilizer has a role of conservation of both Moisture and Fertility and improving soil structure.After active ingredient releasing,silicon-potassium fertilizer leaves half the substance (non-active ingredient)in soil.

熟料单矿物在酸溶液中的化学行为研究表明，硅钾肥矿物在有机弱酸中的化学活性较好，影响硅钾肥肥效发挥的因素是土壤pH值和土壤的去硅化程度，还有土壤有机质的含量与种类；硅灰石在盐酸溶液中化学行为表明，在反应体系pH不小于2的情况下，硅钾肥矿物大量溶出硅酸根组分；溶解残余物表观密度降低、DBP吸着率和比表面积增加表明水合二氧化硅是以多孔形式存在，为硅钾肥具有保水保肥、改良土壤结构的提供了矿物学依据。
