Plant root soil fixation technology plays an important role in preventing and controlling soil landslides.In order to deeply understand the interaction mechanism of plant roots and soil,based on existing research results,VOSviewer software was used to conduct keyword cluster analysis of the literature in the field of plant roots soil consolidation from 2000 to 2023,and the commonly used methods for plant roots soil consolidation test research were obtained.Root soil composite shear test,root tensile test,root configuration test and in-situ pullout test,and the applicability and application of the four test methods were classified and summarized.The research progress of each test method was reviewed in detail,and the effects of root parameters,soil properties and environmental conditions on soil consolidation were summarized.Future research needs to optimize the test method to more accurately simulate the forces on the root-soil complex under actual conditions to improve the accuracy and representativeness of the test research conclusions.
