Abstract Native pastures in Uruguay grasslands are the main resource for livestock extensive farming. Remote sensing data of Net Aerial Primary Production is a useful tool to enhance knowledge about grasslands dynamics and behaviour. The pasture productivity on grasslands is highly affected by climate and droughts episodes impacts directly on secondary productivity of livestock systems. Using remote sensing data, a harmonic sinusoidal model affected by a "climate coefficient" is proposed to generate prospective scenarios and to study an implementation of the Safe stocking rate concept. This information can be use in extension activity to help farmers to adapt their systems to native grass dynamics on the adaptive management paradigm.

乌拉圭原生草原净空中初级生产模型及其在安全放养率概念中的应用

摘要 乌拉圭草原的原生牧场是畜牧业粗放养殖的主要资源。净空中初级生产的遥感数据是增强对草地动态和行为知识的有用工具。草原上的牧场生产力受气候影响很大，干旱事件直接影响畜牧系统的次级生产力。使用遥感数据，提出了受“气候系数”影响的谐波正弦模型，以生成预期情景并研究安全库存率概念的实施。该信息可用于推广活动，以帮助农民根据适应性管理范式使他们的系统适应本地草的动态。
