摘要
为了科学制定木兰林区内华北落叶松的经营规划,通过分析18株华北落叶松年轮宽值,建立林区华北落叶松标准年表,研究木兰围场地区月平均气温和月总降水量对华北落叶松生长的影响,结果表明:在木兰林区,3、5、6、7、8月份气温与华北落叶松生长呈极显著或显著负相关,其中华北落叶松年轮指数在当年5-7月与气温达到-0.574的极显著负相关,表明月平均气温对其有极显著限制作用;在当年7月,华北落叶松年轮指数与降水量达到0.320的极显著正相关,表明月降水量对华北落叶松生长具有显著促进作用。
For the sake of scientific business planning of Larix principis-rupprechtii Mayr in Mulan forest area, the influence of the average annual temperature and monthly total rainfall of Mulan forest area on its radial growth were studied by its annual ring width analysis of 18 strains from Mulan forest area to establish its standard chronology. The results showed a very significant negative correlation between Larix principis-rupprechtii tree-ring index and the air temperature reaching -0. 574 in 5 -7 month, which indicated the monthly average temperature had significant constraints on its function. But its tree-ring index showed a very significant positive correlation with 0. 320 rainfall in July, which indicated that monthly rainfall had a significant role in promoting the radial growth of Larix principis-rupprechtii.
