Characteristics of soil moisture under different vegetation coverage in Horqin Sandy Land, northern China

Abstract: Vegetation restoration as an effective sand fixation measure has made great achievements in China. However, soil water conditions deteriorate with the development and maturity of sand-fixing vegetation. In this study, we investigated the relationship between soil water content (SWC) and vegetation coverage (VC) at different portion (top, middle and bottom) on ten sand dunes during the growing season (April to October) in Horqin Sandy Land, northern China. We analyzed the temporal and spatial variation characte… Show more

“…5), the habitat illumination and soil moisture in forest community were decreasing during the study period according to direction of biplot arrows. Obviously, it was caused by undergrowth development, causing changes in et al, 2016b; Yang et al, 2018). At the same time, anthropogenically maintained conditions of Plot2 did not differ significantly between study years (Fig.…”

“…This could be due to the increased rate of soil moisture depletion, reduced infiltration rate [82], and loss of incoming rain through surface runoff [73] over the summer growing season. According to Yang et al [83], rainfall storage occurred in April and May (months in spring) because of soil water consumed over the wet months from June to mid-September (summer season) and recovery of soil water from late September to October (months of the autumn season). Consequently, the contribution of summer rainfall to soil moisture storage is limited; therefore, this could partly be the reason for the low correlation between ASM and summer rainfall in the UBNB.…”

“…In the control area, the soil was extremely droughty and poor, and the vegetation cover was also the lowest. The soil moisture and nutrients conditions are the preconditions that regulate the plant growth on the sand dune [36]. The soil moisture and nutrient conditions were improved greatly in the sandbag area.…”
