摘要/Abstract

摘要： 黄土丘陵区坡面尺度生物结皮多是由藻、藓和地衣等以不同比例、不同方式组合的一个复杂群落结构,显著影响水分入渗,但目前混合生物结皮水分入渗与其群落结构之间的关系仍不清楚,妨碍了对坡面尺度生物结皮土壤渗透性的评估。本研究测定了藻结皮、藓结皮及藓结皮盖度分别为<15%、15%～30%、30%～45%、45%～60%、＞60% 5个不同藻藓比例的混合生物结皮的稳定入渗速率,采用主成分分析和通径分析揭示混合生物结皮水分稳定入渗速率的影响因素,明确混合生物结皮水分稳定入渗速率与群落结构之间的关系。结果表明: 藻结皮和藓结皮土壤饱和导水率分别为0.66和2.40 mm·min^-1。藓结皮盖度从<15%到>60%的混合生物结皮的稳定入渗速率为0.80～2.30 mm·min^-1。混合生物结皮水分稳定入渗速率主要与藓结皮盖度和藓结皮改善的土壤孔隙结构密切相关,相关系数分别为0.636(P=0.011)和0.835(P=0.000)。通过藻结皮和藓结皮土壤饱和导水率与盖度加权预测的混合生物结皮水分入渗量(y)与混合生物结皮实测水分入渗量(x)具有极显著相关关系(r=0.945),二者拟合的线性函数为y=0.85x(R²=0.98,P<0.05)。本研究明确了混合生物结皮水分入渗与单一组成生物结皮水分入渗之间的关系,为准确评估该区生物结皮水文过程提供了科学依据。

Abstract: Biological soil crusts (biocrusts) are the mixed community composed of different ratios of cyanobacteria, mosses, and lichens at the slope scale in the Hilly Loess Plateau region. Biocrusts significantly affect water infiltration in this area. The relationship between infiltration rate and community structure of mixed biocrusts is unknown, which would hinder the assessment of soil permeability of biocrusts at the slope scale. We measured the stable infiltration rate of cyanobacteria, moss, and mixed biocrusts with different proportions of cyanobacteria and moss including moss coverage of <15%, 15%-30%, 30%-45%, 45%-60% and >60%, respectively. The principal component analysis and path analysis were used to understand the influencing factors of stable infiltration rate of mixed biocrusts, and to clarify the relationship between the stable infiltration rate and the community structure of mixed biocrusts. The results showed that the saturated hydraulic conductivity of cyanobacteria and moss crusts was 0.66 mm·min^-1 and 2.40 mm·min^-1, respectively. The stable infiltration rates of mixed biocrusts with moss coverage <15% to >60% were 0.80-2.30 mm·min^-1. The stable infiltration rate of mixed biocrusts at the slope scale depended on moss coverage and its improvement on soil pore structure, with the correlation coefficients being 0.636 (P=0.011) and 0.835 (P=0.000) respectively. Herein, the saturated hydraulic conductivity and coverage of cyanobacteria and moss confirmed the weighted prediction of water infiltration volume (y) i.e., a significant correlation (r=0.945) with the measured water infiltration volume (x) of mixed biocrusts. The linear fitting of measured and predicted water infiltration volume of mixed biocrusts was y=0.85x (R²=0.98, P<0.05). This study clarified the relationship between water infiltration of mixed biocrust community composition and individual biocrust composition, which provided a scientific basis for accurately evaluating the hydrological process of biocrusts in this area.
