中文摘要:
      土壤水热因子是影响作物生长发育的重要因子,尤其是在黄土高原自然植被恢复过程中。通过对黄土高原不同自然植被恢复阶段的土壤水分和温度的长期监测,研究植被恢复过程中土壤温度和水分的动态变化及其相关性。结果表明:8-10月草地群落的土壤温度显著高于其他群落,11月辽东栎林群落的土壤温度显著高于其他群落,随着植被恢复,土壤温度变化的范围和峰值均有不同程度的减小,土壤水分有所减少,但并不影响土壤水分随时间变化的总体趋势,不同植被恢复阶段土壤温度和水分呈显著负相关,植被恢复过程中土壤水分有一定的时间稳定性。研究结果可为黄土高原自然植被恢复的有效管理和可持续发展提供科学参考。
英文摘要:
      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.
