- [目的]阐明黄土高原长期退耕还林(草)对土壤水文物理性质的影响,有利于完善黄土高原土壤水文研究,为黄土高原后续生态恢复提供理论依据。[方法]通过采样分析和原位双环入渗试验,针对不同植被恢复类型的土壤有机质、容重、孔隙度、含水量以及入渗性能等土壤水文物理性质进行了分析。[结果]植被恢复对土壤物理性质影响显著(p<0.05),造成的变化在0—40 cm土层表现得最为明显,有机质、孔隙度和>0.25 mm水稳性团聚体含量显著增加,容重显著降低。退耕还林(草)增强了土壤的入渗能力,相较于农地,绥德和神木草地的初始入渗分别增加了50%和31%; 绥德和神木地区的草地、灌木、林地的稳定入渗速率分别增加了76%,11%,19%和53%,128%和58%。土壤稳定入渗和平均入渗与容重呈显著负相关关系(p<0.05),与总孔隙度、毛管孔隙度(p<0.05)和有机质含量(p<0.01)呈显著正相关。[结论]植被恢复对土壤水文物理性质影响显著,土壤入渗性能显著提高,有机质含量、容重和孔隙度对入渗性能有显著影响。
- Abstract:
- [Objective] Elucidating the influence of long-term returning farmland to forest, shrubland, and grassland on soil hydrophysical properties on the Loess Plateau is conducive to improving soil hydrology research and providing a theoretical basis for the subsequent ecological restoration of the Loess Plateau. [Methods] Through sampling analysis and double-ring infiltrometer test, the soil hydrophysical properties such as soil organic matter, bulk density, porosity, soil moisture and infiltration capacity of different vegetation restoration types were analyzed. [Results] Vegetation restoration had a significant impact on soil physical properties(p<0.05), and the resulting changes were most obvious in the 0—40 cm soil layer. The content of organic matter, porosity and the stability of water-stable aggregates significant increased, the soil bulk density decreased significantly. Converting farmland to forest, shrubland, and grassland enhanced soil infiltration capacity. Compared with farmland, the initial infiltration of Suide and Shenmu grassland increased by 50% and 31%, respectively; the stable infiltration rates of grassland, shrubs and forest in Suide area increased by 76%, 11% and 19%, respectively; those in Shenmu area increased by 53%, 128% and 58%, respectively. Soil stable infiltration and average infiltration were significantly negatively correlated with bulk density(p<0.05), and significantly positively correlated with total porosity, capillary porosity(p<0.05)and organic matter content(p<0.05). [Conclusion] Vegetation restoration has a significant effect on soil hydrophysical properties, soil infiltration performance has been significantly improved, and organic matter content, bulk density and porosity have significant effects on infiltration performance.
