摘要:
通过测定川西北高山/亚高山区6种典型土壤类型(亚高山草甸土、高原草甸土、暗棕壤、棕壤、黄棕壤、褐土)不同土层深度有机碳含量、容重、孔隙度、持水蓄水及渗透性能,揭示了6种土壤类型孔隙度及水文效应差异及在垂直空间的变化规律,建立了6种土壤类型渗透速率与时间关系的渗透模型。结果表明:(1)0-100 cm 土层6种土壤类型有机碳含量均值表现为:高原草甸土>亚高山草甸土>褐土>棕壤>黄棕壤>暗棕壤;不同土壤类型有机碳含量在相同土层差异显著(P < 0.05 ),同一土壤类型随土层加深而减小;容重在0.87-1.79 g cm-3之间,随土层加深容重增加;总孔隙度在37.6-55.81%。(2)0-100 cm土层自然贮水量、最大持水量、非毛管持水量平均值亚高山草甸土最高;田间持水量、涵蓄降水量黄棕壤最高;随土层加深最大持水量、毛管持水量、非毛管水量、田间持水量、涵蓄降水量增加。(3)6种土壤类型均表现为初渗速率大于稳渗速率,土壤类型间差异显著,渗透速率与时间呈幂函数关系,接近于考斯加柯夫公式。综上表明:土壤类型的差异对孔隙特征和水文效应产生了一定影响,结果可为川西北地区不同土壤类型背景下生态环境恢复重建、生态系统水源涵养功能评价提供理论依据。(图2 表5 参26)
Abstract:
This paper reveals that the differences of porosity, hydrological effect characteristic and the change law variation at spatial scales of 6 soil types (cinnamon soil, yellow brown soil, brown soil, dark brown soil, plateau meadow soil, subalpine meadow soil) in northwestern Sichuan Alpine and Subalpine Mountains. By measuring soil organic carbon content, bulk density, porosity, water storage and water permeability in different soil types and different depths, and setting up the model of soil infiltration rate and time. The results showed that: (1) Average organic carbon content of 6 soil types in 0-100 soil layer was as follows: plateau meadow soil > subalpine meadow soil > cinnamon soil > brown soil > yellow brown soil > dark brown soil; In the same soil layer, organic carbon content of 6 soil types was significantly different, and decreased with depth. The bulk density of 6 soil types was 0.87-1.79 g cm-3, which increased with depth. The total porosity of different soil types was 37.6-55.81%. (2) N atural water storage, maximum water holding capacity and non-capillary water holding capacity of subalpine meadow soil were the highest in 0-100 cm soil layer. field water capacity, available soil water storage of yellow brown soil were the highest. The maximum moisture capacity, capillary water holding capacity, non-capillary water holding capacity, field water capacity and available soil water storage increase with depth. (3) According to the water infiltration model in this study, 6 soil types show that the initial infiltration rate was greater than the stable infiltration rate, and the relationship between infiltration rate and time could be described by the power function, which was close to the Kostiakov’s equation. The difference of soil types has a certain influence on porosity and hydrological effects , these results could provide theoretical basis for the restoration and reconstruction of ecological environment and evaluation of water conservation function of ecological system in different soil types in Northwest Sichuan.
