| 摘 要： | 利用圆盘入渗仪测量6种处理（无生物结皮、生物结皮、长芒草、长芒草＋生物结皮、柠条、柠条＋生物结皮）下水分的入渗特征,并进行对比分析。结果表明：①无论有、无植被,生物结皮的存在都会阻碍水分的入渗,无生物结皮的稳定入渗速率和累积入渗量均大于有生物结皮;植被的存在,加剧了生物结皮的阻水性。②Kostiakov模型对无结皮、长...

| Abstract: | In this study,the disc infiltrometers were used to measure soil water infiltration under 6 kinds of treatments(the regions where there was no microbiotic crust,there was microbiotic crust,Stipa bungeana grows,S.bungeana grows with microbiotic crust,Korshinsk peashrub grows,K.peashrub grows with microbiotic crust),and the measured data were compared and analyzed.The results are as follows:(1) Microbiotic crust impeded soil water infiltration whether there was vegetation or not,and the stable infiltration rat... |
