| Abstract: | Soil hydrothermal factor is an important factor affecting the growth and development of crops, especially during the natural vegetation restoration on the Loess Plateau. The dynamic changes and correlations of soil temperature and water in the process of vegetation restoration were studied through long-term monitoring of soil water and temperature in different stages of natural vegetation restoration in the Loess Plateau. The results showed that soil temperature in the grassland community from August to October is significantly higher than other communities, and it is significantly higher in Quercus liaotungens community in November, with the vegetation restoration, the range and the peak of soil temperature decreased with different degree, soil water content decreased but it does not affect the overall varying trend over time, soil temperature and soil water content have significantly negative correlation in the different stages of vegetation restoration, and the soil water content has a certain time stability during the restoration process. The research results provide scientific reference for the effective management and sustainable development of natural vegetation restoration on the Loess Plateau. |
