Relationship Between Plant Community Characteristics and Soil Water Storage Along Typical Grassland Succession in Loess Hilly Region
[Objective] To identify the relationships between plant community characteristics and soil water storage following natural vegetation restoration after farmland abandonment
in order to provide a reference for vegetation restoration on the Loess Plateau. [Methods] Samples were collected in plots with different natural restoration years (3
8
13
46
66 and 89 a)
to quantify the changes in soil water (0-100 cm) and ecological characteristics such as plant biomass and plant diversity in the Yunwu Mountain in Guyuan City
the Ningxia Hui Autonomous Region. [Results] With the succession of grassland
the plant community coverage
biomass and species diversity index increased dramatically at the early successional stages (before 13 a)
and then gradually stabilized. Soil water content showed an increasing trend along the vegetation restoration years. The succession of vegetation communities had no significant effect on soil water storage in the 0-40 cm soil depths
but in the later stage of succession
the water content below 40 cm depths showed an obvious decreasing trend. Vegetation biomass and species diversity index were positively correlated with soil water content at 0-10 cm depths. [Conclusion] Soil water in the topsoil played a positive role in the variations of plant biomass and species diversity induced by vegetation restoration. However
the increase of the root biomass in the deep soil increased the consumption of soil water storage
especially in the later successional stage.
