在吕梁山南段云丘山，以橿子栎为主要研究对象，采用野外调查和室内实验相结合的方法，对比叶面积(SLA)、叶面积(LA)、叶干物质含量(LDMC)、叶长宽比(L/W)、叶绿素含量(Chl)以及叶氮含量等有代表性的指标进行分析.结果表明：(1)随着海拔梯度的增加，橿子栎 L/W、Chl、SLA、LA、单位面积的叶氮含量(N area )、单位重量的叶氮含量(N mass )、叶饱和鲜重和叶干重均呈先上升后下降的趋势，在海拔1180 m 处有最大值；LDMC 与海拔呈显著负相关(P ＜0．05)；(2)橿子栎 LA 与 SLA 和 N mass 呈极显著正相关关系(P ＜0．01)，与 LDMC 呈显著负相关关系(P ＜0．05)，与 N area呈极显著负相关关系(P ＜0．01)；(3)橿子栎叶片 SLA与 L/W 呈显著正相关(P ＜0．05)，与 N mass 呈极显著正相关关系(P ＜0．01)，橿子栎叶片 SLA 与 LDMC 和N area呈显著负相关关系(P ＜0．05)；(4)橿子栎 LDMC 与 N area 呈显著正相关(P ＜0．05).通过对云丘山景区橿子栎叶片性状随海拔变化规律的研究，可以探索橿子栎叶片性状与海拔梯度变化的关系以及最适生长环境，从而为景区橿子栎林的保护和抚育提供理论依据，为合理开发橿子栎林资源提供基础资料.

Combining field investigation and indoor experiments of Quercus baronii in Yunqiu scenic spot of south Lüliang Mountain,some representative indicators such as specific leaf area (SLA),leaf area (LA),leaf dry matter content (LDMC),leaf aspect ratio (L/W),chlorophyll content (Chl),and leaf nitrogen content were performed and analyzed.The results were as follows:(1)As elevation gradient rises up,Q.baronii aspect ratio,Chlorophyll,SLA, LA,N area ,N mas ,saturated fresh and dry weight,all of their indicators had a first-increase-and-then-decrease trend and their peak value appeared at the altitude of 1 180 m;however,LDMC had a significant negative correlation (P <0.05) with the elevation gradient;(2)The LA of Q.baronii was significantly positively correlated with SLA and N mas (P<0.01),negtively with leaf dry matter (P <0.05),but obviously negatively with N area (P <0.01);(3)The leaf SLA of Q.baronii had a positive correlation with leaf length-width ratio (P <0.01)and an obvious positive correlation with Nmas (P <0.01),while significantly positively correlated with LDMC and N mas (P <0.05);(4)LDMC of Q. baronii was significantly positively correlated with N area (P <0.05);This paper studied the correlation between leaf character factor of Q.baronii and the altitudinal as well as the most suitable growth condition for Q.baronii by ob-serving the variation regulations of Q.baronii with different elevations in Yunqiu Mountain scenic spot.Accordingly,this result could provide a theoretical support for protecting and cultivating Q.baronii and a basis for exploiting and utilizing Q.baronii resource scientifically.
