| 摘 要： | 对柞本林同偿同层次叶片净光合强度和呼吸强度日变化的定位观测表明，林下幼树净光合强度日变化为单峰曲线，林冠中部和下部为双峰曲线，林冠表面为多峰曲线，各层次光合强度差异显著；呼吸强度各层次无显著差别。

| Abstract: | Based on field and orientation. this paper analysed net photosythesis and respiration intensity's diurnal changes the leaves of understory in oak forest show single peak curve. those in the middle and bottom of canopy show binomial peak curve and these in canopy cover show multi -peak curve. All of them have remarkable difference. But respiration intensity of four layers hasn't. These results will be prepared to further study energeties. |
