<h2 class="text-center">3.草地产草量估算方法</h2>
<p>可实地测量获得,活利用植被指数遥感数据与实测产草量建立的经验公式获得,也可以基于生态模型模拟的植被净初级生产力(NPP)数据计算获得:</p>

式中:<p></p>
<ul>
<li>GY -- 草地产草量(g/m<sup>2</sup>);</li>
<li>NPP -- 植被初级生产力(g/m<sup>2</sup>);</li>
<li>A<sub>NPP</sub> -- 草地植被地上部分生产力(g/m<sup>2</sup>);</li>
<li>B<sub>NPP</sub> -- 草地植被地下部分生产力(g/m<sup>2</sup>);</li>
<li>BGB -- 草地植被地下部分(根系)生物量(g/m<sup>2</sup>);</li>
<li>liveBGB -- 活根系生物量占总根系生物量的比例(%);</li>
