| 英文摘要 | Alpine treeline is an important ecological boundary, marked by a change in site conditions and plant communities when crossing the forest limit, and tree growth at treeline is strongly constrained by the harsh environment. Finer resolution studies of tree radial variation on short temporal scales can be useful to explore the main physical variables that trigger the radial growth. From 19(th) Oct. 2008 to 25(th) Oct. 2009, we continuously monitored the stem radial variation of Picea meyeri Rebd. Et Wils trees using point dendrometers, at the treeline of Luya Mountains (altitude 2700 m a.s.l.), North China. Our results showed that there were two reverse daily variation patterns in the warm and cold seasons, which were related to the daily transpiration course and daily stem freeze-thaw cycles, respectively. Annual stem radial growth of Picea meyeri was divided into the four distinct periods: 1) spring stem rehydration, 2) summer stem rapid growth, 3) autumn stem dehydration contraction and 4) winter stem stagnation. The stem radial variation of Picea meyeri at the alpine treeline was closely dependent on climate conditions. Soil temperature was the most important factor affecting radial growth, which determined the initiation of radial growth and the cambial activity during the growing season. |
