Abstract: On the basis of the vegetative cement-soil configuration model,in order to investigate the effects of cement, habitat material modifying agent,organic material and organic fertilizer on the vegetation performance of the vegetative cementsoil,the effects of four factors on the vegetation performance of the vegetated cement soil were analyzed through the single-factor proportioning test of cement,habitat material modifying agent,organic material and organic fertilizer. The results showed that each factor had different degrees of influence on the vegetation performance of the vegetative cement-soil,with the increase of cement dosage,the capacity,compactness and pH of the vegetated cement soil gradually increased,with the maximum increase of 7. 4%,51. 6% and 9. 6% respectively,and the porosity gradually decreased,with the maximum decrease of 4. 2%;While the amendment adjusted the pH of the vegetative cement-soil,it contributed to the organic matter content and quick-acting nutrients of the vegetative cement-soil to different degrees,and could effectively improve the biological characteristics of the vegetative cement-soil. The organic materials and organic fertilizers can improve the physical structure of the vegetative cement-soil and enhance the nutrient level of the vegetative cement-soil,thus improving the vegetative properties of the vegetative cement-soil. The results of this study can provide a theoretical basis for the application of ecological slope protection of vegetative cementsoil.
