Vegetation dynamics and environmental variation in Kamchatka

我们建立了几个永久的地块1公顷的森林动态研究在堪察加半岛。我们进行了树木大小（茎直径，树高），位置的地块和物理环境，如光照强度和温度的测量。云杉幼苗在树冠下而不是在林隙中定植。因此，在温带和热带森林中众所周知的林隙更新动态在堪察加半岛森林中不起作用。这是我们在堪察加发现的新现象。我们假设这是因为堪察加半岛的强光胁迫、低温、低降水等恶劣环境。我们还进行了调查，在Koryto冰川重建过去的气候变化（温度，降水）在堪察加半岛的森林动态进行比较。我们发现，森林火灾发生更频繁的降水量较低的年份。森林火灾对森林动态和气候变化的影响也被调查，通过使用模拟模型。

We established several permanent plots of 1 ha for studying forest dynamics in Kamchatka. We carried out measurements of tree sizes (stem diameter, tree height), positions in the plots and physical environments such as light intensity and temperature. Picea seedlings established under the tree crown but not in gaps. Therefore, gap regeneration dynamics, which is a well known phenomenon in temperate and tropical forests, does not work in the forests of Kamchatka. This is a new phenomenon we found in Kamchatka. We hypothesize that this is because of severe environments such as high light stress, low temperature, low precipitation, in Kamchatka. We also carried out investigations in the Koryto glacier for reconstructing past climate change (temperature, precipitation) in Kamchatka for comparison with forest dynamics. We found that forest fire occurs more frequently in years with lower precipitation. Effects of forest fires on forest dynamics and climate change have also bee investigated by using simulation models.
