GU Guanghe, FAN Haoming, WANG Yansong, et al. Morphologies Characteristics and Driving Factors of Gullies in Black Soil Region of Northeast China[J]. Bulletin of Soiland Water Conservation, 2015, 35(3): 30-33. DOI: 10.13961/j.cnki.stbctb.2015.03.013.
[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.
