water uptake ratio.xlsx

The ratio of water absorbed by a theoretical plant canopy with a tree rooting distribution or a grass rooting distribution. The ratio is the ratio of total water absorbed across three growing seasons. The ratio was calculated for soils where 10%, 50% or 90% of the roots in the soil had a 'tree-shaped' rooting distribution. Results are shown for four sites in Kruger National Park that represent a two-way factorial combination of mesic (750 mm precipitation), dry (450 mm precipitation), sand, or clay soil conditions.

本数据集旨在计算具备树木根系分布或草本根系分布的理论植物冠层的吸水量比值。该比值为两类冠层在三个完整生长季内的总吸水量之比。计算针对土壤中10%、50%或90%的根系呈‘树状’分布的情形开展。研究结果展示了克鲁格国家公园内四个样地的相关数据，这四个样地覆盖了水分条件（中生生境：年降水量750mm；干旱生境：年降水量450mm）与土壤类型（砂土、黏土）的双因素全因子组合。
