Abstract

The effects of long-period climate change and fluctuations of climate factors in the recent decades on the Scots pine (Pinus sylvestris) growing in the Kerzshenskii State Nature Biosphere Reserve (the Nizhny Novgorod region) are considered. It is found that the amount of precipitation forming phytocenoses water availability is the most important climatic factor limiting the pine growth and development. A competition between the linear and radial pine increments for the water resource, which directly depends on the amount of precipitation, is identified. The direct response of the radial to linear increment is found, because these are the height tree growth and the crown development that induce the successful stem diameter formation. It is noted that due to the widespread occurrence and variety of environmental impact signals, Pinus sylvestris is an optimum object for the environmental monitoring of forest ecosystems, which makes its further investigation in a changing climate essential.

伏尔加河地区降水对北方林分生长的影响

摘要

近几十年来长期气候变化和气候因子波动对苏格兰松树（Pinus sylvestris）生长在Kerzshenskii国家自然生物圈保护区（下诺夫哥罗德州）中。发现形成沉淀的植物素水的可用性是限制松树生长和发育的最重要的气候因素。确定了水资源的线性和径向松树增量之间的竞争，该竞争直接取决于降水量。发现了径向对线性增量的直接响应，因为这些是引起成功的茎杆直径形成的身高树的生长和冠的发育。应当指出，由于环境影响信号的广泛发生和变化，樟子松 是对森林生态系统进行环境监测的最佳对象，这使得在不断变化的气候中进行进一步研究变得至关重要。
