Abstract:

采用SF-300热脉冲树干液流仪,分析比较了准噶尔盆地南缘人工种植和原生条件下,梭梭树干液流及其土壤水分的变化,建立了人工种植梭梭树干液流速率与气象因子的最优回归方程。结果表明人工种植梭梭日累积液流量过程线呈近似“S”型,与土壤含水率具有极显著的相关性;液流速率日变化多呈双峰型,昼夜变化明显,对气温的时滞约1h;原生梭梭耗水特征相对稳定,日累积液流量过程线近似直线型,与土壤含水率无相关性,液流速率日变化多呈多峰型,无明显日过程。观测期人工梭梭单位面积液流通量平均为0.240L/(cm2.d),是原生梭梭的1.5倍;降雨后人工和原生梭梭液流速率峰值分别比降雨前提前3h和30min。
