The impoundment of dams can significantly alter shorelines, hydrological
regime, sediment and nutrient cycle. With the completion of Chushandian
reservoir dam, land use types around the reservoir have been profoundly
affected by flooding. As yet, the characteristics of soil properties on
different land use types in new built reservoir have not been fully
elaborated. In this work, we investigated the variation of soil physical
and chemical properties at distance scale for different land use types
after short-term inundating. Soil physical properties, chemical
properties, soil particle structure were determined. This study reported
that short-term inundating had impacts on soil physical and chemical
properties of different land use types. Our results indicated that the
soil physical and chemical properties at 0 m site of each land use types
may be mainly affected by the nutrient status of overlying water. The
soil TN, TC of all land use types decreased gradually with the increase
of distance from river bank, among which the contents of TN and TC at W2
were significantly higher than those at other sites. Compared with
woodland, both abandoned cropland and grass land showed the phenomenon
of soil particle loss and nutrient leaching. The characteristics of low
NH4-N and high NO3-N were observed in the woodland after flooding, which
may be related to denitrification. The main influencing factor is soil
microbial activity at W20. The main influencing factor is soil nutrient
status At W2. And at abandoned cropland and grassland, the main
influencing factor is soil physical properties. The response of
different land use types to short-term flooding may be mainly related to
the degree of vegetation coverage. Abandoned cropland showed stronger
resilience, while grassland showed stronger tolerance. The present study
suggested that early and timing restoration will be an effective way to
repair the riparian habitat.
