| 摘要: |
| 【目的】秸秆、有机肥、生物炭等众多有机物料被广泛应用于农业实际生产之中，改良土壤结构是其主要效用之一。在此基础上，定量评价改良效果成为当前国内外的研究热点。【方法】本文对不同有机物料对土壤结构的改良效应及其定量化评价方法进行了归纳和评述。【结果】在低温干旱地带，有机肥和聚丙烯酰胺对土壤结构的改良效果较好；在气候多变以及高温潮湿地区，秸秆的改良效果更优；生物炭适用于改良粗质土壤结构；木本泥炭适用于改良细质土壤结构；为多尺度、定量化地评价有机改良剂对土壤结构特性的影响，土壤原状结构的无损获取技术以及相对应的数字图像处理方法成为了当下和未来的主要研究手段。【结论】在今后的研究中应当根据土壤的理化性质合理选择改良物料，通过多学科交叉对各尺度的土壤物理结构进行优化，对未来研究土壤结构的新方法等作了展望。 |

| Abstract: |
| 【Objective】 Straw, organic fertilizer, biochar, and many other organic materials are widely used in agricultural production. Improving soil structure is one of its main effects. On this basis, quantitative evaluation of improvement effect has become one of the research hotspots at home and abroad. 【Method】This paper summarized and commented on the improvement effects of different organic materials on soil structure and their quantitative evaluation methods. 【Result】In low-temperature and arid areas, organic fertilizer and polyacrylamide have a better improvement effect on soil structure, while in areas with changeable climate and high temperature and humidity, the improvement effect of straw is better. Biochar is suitable for improving the structure of coarse soil, while woody peat is suitable for improving the structure of fine soil. In order to quantitatively evaluate the influence of organic amendments on soil structure characteristics in a multi-scale, the non-destructive acquisition technology of soil undisturbed structure and the corresponding digital image processing method have become the main research means at present and in the future. 【Conclusion】 In the future research, we should reasonably select improved materials according to the physical and chemical properties of soil, optimize the soil physical structure of each scale through multi-disciplinary intersection, and look forward to the new methods of studying soil structure. |
