The ability to quantify vt. 定量,表示份量,称量 plant root water use is essential for sound健全的,可靠的,合理的management policies政策,方针,策略with regards to顾及,考虑both production U生产;U产量;C产品,作品and the environmental impacts of the soil plant system.
测量植物根系中的水分这一应用对于制定正确完善的政策是非常必要的。这样制定出的政策不仅可以考虑到产量还可以考虑到对土壤体系环境的影响。
The macroscopic” 肉眼可见的root water uptake吸收models incorporating合并者,法人创立者dynamic 动力的, 动态的, 有活力的 and non-uniform root distribution分布, 分发, 分配, 散布 and water uptake capabilities have been used in various cultivated crop ecosystems. 生态系统

However, the use of these models in rangelands牧场 , and other native ecosystems where many plant species coexist, faces a major difficulty due to the lack of accurate and site-specific特定场地root distribution and rooting depth data. 数据
然而这种模型在牧场中的应用和与当地种类繁多的植物生态系统共存面临着一个主要的困难，这是由于缺乏精确的和特定的根部分配和根系长度数据

然而在牧场中， 在精确的土壤水分动态下我们可以更好的了解整个生态过程。 例如光合作用、碳汇、氮的矿化作用饲料生产和利用
One of the most important progresses made using the macroscopic root uptake models perhaps is the concept观念, 概念, 想法of the water stress compensation, 补偿, 赔偿, 赔偿金in which the water stress-caused reduction in root water uptake from on part of the root zone can be compensated补偿, 赔偿, 付报酬through the enhanced uptake from another part of the root zone with a better water availability. 有效, 有用, 有益,可得到的人
Experimental evidence has shown that including the water stress compensation can significantly improve the predicted soil water contents , especially for the lower part of the root zone, under various weather conditions for cultivated crop ecosystems.
实验数据已经显示 包括在各种各样的天气条件下种植作物的生态系统中，水压补偿可以显著提高土壤中的水含量特别是根的下半部分，
In this paper, we tested the possibility of modeling the root distribution , soil water flow and plant
Water uptake based on field measured data of soil water content, soil hydraulic characteristics and leaf area index on rangelands under moderate grazing, with an emphasis given to the evaluation of model performance and predictions in relation to different choices of soil physical and root distribution parameters, and in particular, to the situations with and without the water stress compensation mechanism.
