冀北山地油松、落叶松径向生长对气象因子的响应
|
摘要
为探索冀北山地油松与落叶松径向生长与气象因子的关系,选取承德围场地区立地条件相似的油松与落叶松2个样本作为研究对象,研究二者的生长规律,并结合该地区降水与气温2个主要气象因子,研究气象因子对油松、落叶松径向生长的影响。结果表明:1)冀北山地油松、落叶松2个树种生长与气温和降水都有较为显著的相关性,其中2、3月份的气温与油松径向生长呈显著正相关,而6月份则呈显著负相关;2)上年12月份的降水与其显著负相关,当年6月的降水与其显著正相关;3)落叶松方面,2、5、6月这3个月份的气温与落叶松径向生长呈显著负相关,上一年11月、当年的3、8、9月的气温与落叶松径向生长呈正相关,但不显著;4)该地区降水与落叶松径向生长总体呈正相关,其中3、5、6、7月份的降水与落叶松径向生长呈显著正相关;5)松径向生长与上一年12月份至当年4月份的气温总体呈正相关,与5—10月份的气温整体呈负相关,与上一年10—12月份的降水呈负相关,与当年4—10月份降水呈正相关;6)落叶松对气象因子响应程度略大于油松,落叶松与降水因子整体呈正相关,与气温呈负相关,说明该区域内气温是落叶松径向生长的限制因素。
In order to explore the relationship between the radial growth and meteorological factors of Pinus tabulaeformis and Larix gmelinii in mountainous areas of northern Hebei Province, two samples of P. tabulaeformis and L. gmelinii with similar site conditions in Chengde Weichang area were selected as research objects to study their growth laws. And the effects of meteorological factors on the radial growth of P. tabulaeformis and L. gmelinii were studied by combining precipitation and air temperature in this area. The results are as follows: 1) There was a significant correlation between the growth of the two tree species and the temperature and precipitation. The temperature in February and March had a significant positive correlation with the radial growth of P. tabulaeformis, but a significant negative correlation in June. 2) The index of annual ring of P.tabulaeformis had a significant negative correlation with the precipitation in December of last year, the index was a significantly correlated with precipitation in June of that year; 3) For larch, the temperatures in February, May and June of this year were negatively correlated with the radial growth of larch; The temperature in November of last year, March, August and September of this year were positively correlated with the radial growth of larch, but not significantly. 4) The precipitation in this area was positively correlated with the radial growth of larch, and the precipitations in March, May, June and July were positively correlated with the radial growth of larch. 5) The radial growth of P. tabulaeformis was positively correlated with the temperature from last December to April of that year, and negatively correlated with the temperature from May to October, and negatively correlated with the precipitation from October to December of the previous year, and positively correlated with the precipitation from April to October of that year. 6) Larch has a slightly greater response to meteorological factors than P. tabulaeformis. Larch was positively correlated with precipitation factors as a whole, and was negatively correlated with air temperature, indicating that air temperature was the limiting factor for the radial growth of Larch in this region.
