防护林在维护干旱区绿洲稳定与风沙灾害防治过程中扮演着十分关键的作用.多枝柽柳(Tama-rix ramosissima)是典型的耐贫瘠多年旱生灌木,是防护林重要的乡土物种之一,而多枝柽柳的蒸腾耗水量和该地区可利用水资源间的平衡决定了其生存和生长状态.文中利用包裹式茎流计于2020年5-10月对多枝柽柳树干液流进行监测,并同步对环境因子进行测量.结果表明:监测期间,多枝柽柳的累计树干液流量为75.43 kg,日均树干液流量为523.8g·d-1,且具有明显的季节性特征;多枝柽柳树干液流速率分别与光合有效辐射、气温和饱和水汽压差呈显著正相关(P＜0.001),与浅层土壤含水量(0-40cm)和中层土壤含水量(40-160cm)无显著...

The shelterbelt forest between oases and desert plays a vital role in preventing aeolian disasters and desertification in arid regions.Tamarix ramosissima(T.ramosissima),a typical perennial and native xerophyte shrub in Northwest China,grows naturally and is widely used in constructing artificial shelterbelt forests.The balance between water consumption and the availability of water determines the survival and growth of T.ramosissima.And global climate change will further increase the pressure on water resources in this region.In this paper,the...
