| Abstract/Contents: | "Water is the decisive factor for vegetation growth in loess hilly ravine area, and check dams play very important roles in ditches with serious soil erosion. The difference in the vegetation coverage, land utilization and soil moisture between the ditches with or without check dam were investigated in the northwest of Zhuanglang County, Pingliang, Gansu Province, using GF-2 remote sensing images and field survey data, and based on Arc Map 10.5 and eCognition 9.0, ENVI 5.3 software platforms. Our results showed that fractional vegetation coverage of the ditches with check dam was 2.17% higher than that of the ditches without check dam. For the ditches with check dam, forest coverage accounted for 31.82% of the total area; while the ditches without check dam was primarily covered by grassland, accounting for 27.53% of the total area. The land utilization area in the ditches with check dam followed the order of forestland > grassland > other land > water area and land for water conservancy facilities; while it followed the order of grassland > Forestland > other land for the ditches without check dam. The soil moisture content of the ditches with check dam increased along the soil depth, but it showed the opposite trend for the ditches without check dam. At soil depth of 180? 200 cm, the soil moisture of the ditches with check dam was significantly higher than that without check dam, which was attributable to higher vegetation coverage. Silt dams in the controlled area of loess gully area could improve the quality and coverage of vegetation. The land utilization of the ditches with check dam channel could be improved due to higher soil moisture, which would play significant roles in controlling soil erosion and improving the ecological environment." |
