  "abstract": "<p>In alpine region of Loess Plateau, by using Li-6400 portable photosynthesis system, light response of gas exchange parameters in&nbsp;<em>S. argentea&nbsp;</em>and&nbsp;<em>H. rhamnoides</em>&nbsp;seedlings under different soil moisture conditions was analyzed. The results showed that&nbsp;<em>Pn</em>,&nbsp;<em>Tr&nbsp;</em>and&nbsp;<em>WUE</em>&nbsp;of the two shrub species were both increased with an increase of the&nbsp;<em>PAR</em>. With continued increase of the&nbsp;<em>PAR</em>,&nbsp;<em>Pn</em>&nbsp;and&nbsp;<em>WUE</em>&nbsp;of&nbsp;<em>S. argentea</em>&nbsp;and<em>&nbsp;H. rhamnoides&nbsp;</em>seedlings declined but&nbsp;<em>Tr</em>&nbsp;still increased. With the increase of soil water content (<em>SWC</em>),&nbsp;<em>Pn</em>,&nbsp;<em>Tr</em>&nbsp;of both two shrub species increased, while&nbsp;<em>WUE</em>&nbsp;increased first, then declined after arriving at the maximum under mild water stress condition (W2). When&nbsp;<em>SWC&nbsp;</em>was in the same, light compensation point (<em>LCP</em>) of&nbsp;<em>S. argentea</em>&nbsp;was lower than that of&nbsp;<em>H. rhamnoides</em>&nbsp;obviously, light saturation point (<em>LSP</em>) and efficiency of light energy utilization of&nbsp;<em>S. argentea</em>&nbsp;were higher than those of&nbsp;<em>H. rhamnoides</em>, and the apparent quantum yield (<em>&alpha;</em>) in the leaves of&nbsp;<em>S. argentea&nbsp;</em>was higher than that of&nbsp;<em>H. rhamnoides</em>. So compared with&nbsp;<em>H. rhamnoides</em>, photosynthetic capacity of&nbsp;<em>S. argentea</em>&nbsp;was stronger at low&nbsp;<em>PAR</em>. Contrastive analysis indicated that under severe water stress condition (W4)<em>H. rhamnoides</em>&nbsp;was easier to be stressed by high&nbsp;<em>PAR</em>. The capacity utilization ratio of low&nbsp;<em>PAR&nbsp;</em>and&nbsp;<em>WUE</em>&nbsp;in&nbsp;<em>S. argentea&nbsp;</em>was higher than that of&nbsp;<em>H. rhamnoides</em>. Thus, it is concluded that the drought-tolerant productivity of&nbsp;<em>S. argentea&nbsp;</em>seedlings was stronger than that of&nbsp;<em>H. rhamnoides</em> seedlings.</p>",
