Abstract
The response of the indexed series of linear increments of Scots pine Pinus sylvestris L., 1753 (class Pinopsida, order Pinales, family Pinaceae) to the current and preceding growing season precipitation in different biotopes of the Kerzhenskii state nature biosphere reserve and Polar Circle reserve is analyzed. For both reserves, a higher (but more stable in magnitude) variability of the increments as compared to wet and dry biotopes over the period of long-term observations is shown for fresh habitats. The results indicate availability of moisture resources in fresh biotopes in both reserves at the stages of renewal bud formation in the previous growing season and internode growth in the current year. Both for wet and dry habitats of the Kerzhenskii reserve, a positive correlation between the increments and total precipitation during the phenophase of internode growth and renewal bud formation is found. The climatic signal obtained in these types of the Kerzhenskii reserve habitats indicates that the lack of moisture is a limiting factor for the pine growth at the key stages of crown development. At the same time, no significant dependences on the amount of precipitation in the current and previous growing seasons were found either for dry or wet habitats of the Polar Circle reserve. The ecosystems of the White Sea coast are characterized by excessive moisture, and even dry biotopes in these ecological and geographical conditions receive sufficient amount of precipitation for the pine growth.

生长季节气候因素对中伏尔加地区和白海沿岸苏格兰松增量的影响
摘要
1753 年赤松Pinus sylvestris L. ( Pinopsida 类, Pinales 目 , Pinaceae )线性增量指数系列的响应) 对 Kerzhenskii 州自然生物圈保护区和 Polar Circle 保护区不同生物群落当前和前一个生长季节的降水进行了分析。对于这两个保护区，在长期观察期间，与干湿生物群落相比，新鲜栖息地的增量变异性更高（但幅度更稳定）。结果表明，在前一个生长季节的更新芽形成阶段和当年的节间生长阶段，两个储备中新鲜生物群落中水分资源的可用性。对于 Kerzhenskii 保护区的干湿生境，在节间生长和更新芽形成的物候期，增量与总降水量之间存在正相关关系。在这些类型的 Kerzhenskii 保护区栖息地中获得的气候信号表明，在树冠发育的关键阶段，缺乏水分是松树生长的限制因素。同时，在极地圈保护区的干燥或潮湿栖息地中，没有发现对当前和以前生长季节降水量的显着依赖性。白海沿岸生态系统的特点是水分过多，即使是在这些生态和地理条件下的干燥生物群落也能获得足够的降水量以供松树生长。在极地圈保护区的干燥或潮湿栖息地中，没有发现对当前和以前生长季节降水量的显着依赖性。白海沿岸生态系统的特点是水分过多，即使是在这些生态和地理条件下的干燥生物群落也能获得足够的降水量以供松树生长。在极地圈保护区的干燥或潮湿栖息地中，没有发现对当前和以前生长季节降水量的显着依赖性。白海沿岸生态系统的特点是水分过多，即使是在这些生态和地理条件下的干燥生物群落也能获得足够的降水量以供松树生长。
