摘要：采用低碱度硫铝酸盐水泥（L-SAC）配制L-SAC水泥土，对其力学性能和植生性能进行了研究。结果显示，随着L-SAC掺入比例的增加，L-SAC水泥土的抗压强度、粘聚力、抗冲刷性能均会得到不同幅度的提高。通过测量8种耐高碱植物在L-SAC掺入比例为8%时配制的L-SAC水泥土中的株高发现，L-SAC水泥土具有良好的植生性能，高羊茅等5种植物均可作为L-SAC植生水泥土的先锋植物。通过分析掺入添加剂的L-SAC植生水泥土的物理力学性能和植生性能，确定了润智生态改良剂等3种可用改性剂。

Abstract：L-SAC cement soil was prepared with low alkalinity sulphoaluminate cement（L-SAC），and its mechanical properties and vegetation properties were studied. The test results show that the compressive strength，cohesion and erosion resistance of L-SAC cement soil will be improved by different degrees with the increase of L-SAC mixing proportion. By measuring the plant height of eight high alkali resistant plants in L-SAC cement soil prepared with 8% L-SAC，the results show that the L-SAC cement soil prepared with 8% L-SAC has good vegetation performance. The five species including Bermudagrass can be used as the pioneer plants of L-SAC planting cement soil. By analyzing the physical and mechanical properties and planting properties of L-SAC planting cement soil mixed with additives，three modifiers including Runzhi ecological modifier are determined.
