Shuitu Baochi Xuebao, 2021 以黄土丘陵区3种典型植被群落（白羊草、铁杆蒿和杠柳）为研究对象，并以退耕1年的撂荒地作为对照（CK），采用原位染色示踪和实验室分析相结合，对比分析不同植被群落斑块格局下的土壤优先流特征，探究植物根系、土壤理化性质对优先流的影响。结果表明：相较CK，植被恢复提高了优先流发育程度；对于各植被斑块，铁杆蒿植被斑块具有最高的染色面积比（45.62%）、最大染色深度（30.30 cm）、优先流比（39.76%）和长度指数（475.90%），杠柳次之，白羊草最小；而对于同一植被群落，除白羊草群落外 ...

Shuitu Baochi Xuebao, 2022 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 ...
