摘要
土壤水分分布的时间稳定性对揭示边坡的水文过程至关重要,但在工程边坡的生态修复过程中却很少考虑到这一点。本研究通过引入时间稳定性分析,评估了不同植被的生态修复对土壤水分分布的影响。首先,构建了草地和灌木覆盖的生态模型边坡,以探讨 0 ∼ 100 cm 深度的土壤水分分布。然后分析了生态坡土壤水分的空间变异性和相关性。通过时间稳定性指数探讨了不同时期空间分布模式的相似性。最后,获得并讨论了各生态坡土壤水分的代表性位置。结果表明,土壤水分分布主要受植被和降雨的影响。不同植被的生态坡地的空间分布模式相似性不同。由于水文效应的不同。在仙人掌覆盖下,坡面土壤水分的空间分布在时间上的相似性较低,而在木兰覆盖下则较好。从相对差异和时间稳定指数来看,最佳代表点大多分布在坡顶,其次是坡中。该研究为合理设计土壤含水量监测点提供了理论依据,也为工程边坡的生态修复提供了指导。
Experiment study on temporal stability of soil moisture content in ecological slopes under different vegetation covers
Temporal stability of soil moisture distribution is crucial to revealing the hydrological process of slope, but rarely accounted for during ecological restoration for engineering slopes. In this study, the effects of ecological restoration with different vegetations on soil moisture distribution were assessed by introducing temporal stability analysis. First, the ecological model slopes with grass and shrub covers were constructed to explore soil moisture distribution at the depth of 0 ∼ 100 cm. Then the spatial variability and correlation of soil moisture in ecological slope were analyzed. The similarity of the spatial distribution patterns among different periods were explored by temporal stability indices. Finally, the representative locations of soil moisture for each ecological slope were obtained and discussed. The results showed that soil moisture distribution was largely influenced by vegetation and rainfall. The similarity of spatial distribution patterns in ecological slopes with different vegetations differed from each other. Due to the difference in hydrological effects. The spatial distribution of soil moisture in slope was less similar in time under Cynodon dactylon cover, while it was better under Multiflora magnolia. Based on relative difference and time stability index, most of best representative locations were distributed at the top of the slope, followed by the middle of the slope. The study provides a theoretical basis for the rational monitoring point design of soil moisture content and a guide for the ecological restoration of engineering slopes.
