Spatially integrated estimates of landscape water fluxes at several contrasting sites.

林地将大量的水(80%的降雨量)排放到大气中，这些水从集水区流失。澳大利亚的年降雨量和季节降雨量都有很大变化。水和集水区管理者需要估计有多少水流出，特别是随着气候和土地利用做法的变化，因为这决定了有多少水可供饮用、用于采矿、林业、灌溉和用于生态系统健康目的。该项目首次将闪烁法用于比较空间平均用水量与开发用于预测景观用水量的模型相结合。通过使用4个不同的生态系统，我们将对植被用水的控制有一个深刻的理解。

Woodlands transpire large amounts (> 80 % of rainfall) of water into the atmosphere and this water is lost from the catchment. Australia experiences large annual and seasonal variations in rainfall. Water and catchment managers need to estimate how much water is transpired, especially as climate and land-use practices change, as this determines how much water is available for drinking, use in mining, forestry, irrigation, and for ecosystem health purposes. This project is the first to combine the use of scintillometry to compare spatially averaged rates of water use with development of a model to predict landscape water use. By using 4 contrasting ecosystems we shall provide a deep understanding of the controls of vegetation water use.
