Using poly lactic acid solution, NaCl particles and Fe3O4 powder as raw material, the preparation can be used for magnetic porous biological scaffold materials for tissue engineering, and the magnetic properties of materials, was used to analyze the microstructure and XRD diffraction. The results show that, this process can not only the formation of porous structure, but also effectively coated magnetic powder materials, keep the good magnetic properties.%采用聚乳酸溶液、NaCl粒子和Fe3O4粉末为原料，制备了可用于组织工程的磁性多孔生物支架材料，并对材料的磁性能、微观结构和XRD衍射进行了分析。结果表明，该工艺不仅可以形成多孔结构，还能有效包裹磁性粉末材料，保留了良好的磁性能。
