- Abstract:
- Chromolaena odorata is one of the main invasive alien weeds in southwest of China. Vegetation replacement restoration is one of the dominant methods to control the C.odorata invasion. However, there was less study on the changes of soil water storage ability in different restoration years. The method of space instead of time was employed to analyze the variations of soil physical property and water storage ability in different restoration years and discuss the effect of different vegetation restoration years on soil water storage ability in C.odorata invasive habitat along karst area in Guangxi. The results showed that the soil physical property was clearly improved during the vegetation restoration process, which showed that the soil bulk density in C.odorata invasive habitat decreased gradually and soil porosity increased with restoration years; soil non-capillary porosity was significantly affected by the vegetation restoration years, however, the soil capillary porosity was less affected; the soil water storage ability was significantly improved following the restoration. Soil non-capillary water-holding capacity and water saturated water content increased with the restoration years, which were higher by 174.9% and 11.6%, respectively, in habitat after 10 years’ restoration than those in CK, while the capillary water-holding capacity was relatively less affected by the ecological restoration and had no significant variation during the restoration process. In conclusion, the vegetation restoration could significantly improve the soil water conservation property in C.odorata invasive habitat of karst area, which reduced the soil erosion and improved the vegetation recovery, and provided important technical and theoretic references for invasive habitats restoration.
