[Objective] To determine the technology requirements for an exclusive project of gully erosion control in a mollisol areas of Northeast China

the gully erosion control practices and models were investigated and summarized

in order to provide technical support for gully erosion control in the mollisol areas in Northeast China.[Methods] Sky and Earth integration and on-site investigation methods were used to obtain the morphological characteristic parameters

image data

and spatial information of gullies controlled by different periods. The gully erosion control practices and models and their effects were investigated.[Results] The gully erosion control practices in the mollisol areas of Northeast China were composed of three types:gully head protection

such as willow falling and stone masonry; gully bed stabilization practices

such as willow watercourse and gabion check dams; and arbors and shrubs providing mixed gully bank protection. The limitations of the existing control practices were identified and improved. The models of gully erosion control were divided into four categories:engineering assisted by vegetation

vegetation assisted by engineering

vegetation

and reclamation.[Conclusion] The current control methods of gully erosion in the mollisol areas of Northeast China achieved remarkable effects

forming mature control models and diversified control practices. However

the phenomena of unjustified models and inappropriate practices existed

and construction quality control and conservation after gully erosion control should be emphasized.
