摘要:
植物类型及土壤营养元素含量等因素随植物群落演替而发生规律性变化,并影响植物根-土复合体抗剪强度。本文选择黄河源区高寒草地,开展植物根-土复合体直接剪切试验及土壤营养元素含量测试,分析区内不同植物群落根-土复合体抗剪强度与土壤营养元素分布之间的关系。结果表明:区内草地沿剖面线方向分布4种植物群落类型,即:高山嵩草-矮嵩草群落、高山嵩草-异针茅-垂穗披碱草群落、青藏苔草+藏嵩草群落和藏嵩草群落; 土壤营养元素含量总体表现出由边坡高海拔位置向低海拔位置逐渐增大的变化特征,有机质含量在坡顶相对最小为59.48 g·kg-1,在坡底最大可达178.13 g·kg-1,增加值为117.65 g·kg-1; 植物根-土复合体黏聚力c值随边坡海拔降低而逐渐增大,即坡顶位置为21.70 kPa,至一级阶地位置达到最大为34.87 kPa; 进一步研究表明,区内根-土复合体抗剪强度与营养元素含量间存在一定程度相关关系,即营养元素含量相对较高位置处其植物根系相对较发达且密集分布,其根-土复合体抗剪强度亦相对较大。研究结果对于科学有效地防治黄河源区高寒草地水土流失、浅层滑坡等现象,具有理论研究价值。
