[Objective] To study the effects of different environment factors in black soil region on gullies morphologies. [Methods] The gully morphologies were measured by differential GPS and their morphological parameters were calculated by GIS, then the reasons of different gully morphologies were analyzed. [Results] The length, area and volume of gullies were positive correlation, and the width, the depth and sectional area of gullies were positive correlation too. The gully length, gully area and gully volume in Wuyi watershed were the biggest, the second were in Gaungrong watershed, and the third were in Jixing watershed. In terms of gully width, gully depth and gully sectional area, that of Gaungrong watershed were the biggest, and then were that in Wuyi watershed and Jixing watershed. The content of soil clay and gravel, soil water-holding capacity,and soil thickness had important influences on gullies morphologies, rainfall factors had less important effects. [Conclusion] Terrain factors are the important factors influencing the gully morphologies. With the growth of terrain factor, the length, area and volume of gullies increased significantly, the sectional area of gully was the biggest when the terrain factor was 36.75.
