- Abstract:
- [Objective]The objectives of this study are to explore the effects of different vegetation restoration patterns on soil physical properties in the reservoir riparian zone, and to provide a scientific basis for the study of vegetation-soil feeding and ecological reconstruction in the reservoir riparian zone. [Methods]The natural restoration and artificial restoration of vegetation in the riparian zone of the Heilongtan Reservoir were taken as the research object, soil samples with different altitude gradients and soil depths were collected. The physical properties of soil bulk density, total porosity, mechanical stability aggregates and other physical properties were compared and analyzed by core method and dry sieve method, respectively. [Results]There were significant differences in soil physical properties between artificial restoration and natural restoration vegetation in the 0—20 cm soil layer(p<0.05), in which the soil bulk density of artificial restoration vegetation was 16.97% lower than that of natural restoration vegetation, while the total porosity, saturated water holding capacity and moisture content of soil increased by 35.00%, 58.45% and 117.63%, respectively, compared with that of natural restoration vegetation. The content of >5 mm mechanical aggregates in soil under artificial restoration vegetation was significantly higher than that under natural restoration vegetation. Multivariate ANOVA showed that the interaction between restoration pattern and water level elevation had the most obvious impact on soil physical properties than other interactions. Redundancy analysis and correlation analysis showed that the restoration pattern was the main controlling factor for the spatial differentiation of soil physical properties in the riparian zone of the Heilongtan Reservoir. [Conclusion]Artificial vegetation restoration can effectively improve soil physical properties, and it is suggested to carry out artificial vegetation restoration reasonably in the riparian zone of the Heilongtan Reservoir to improve soil quality.
