Question

Почему широколиственные породы деревьев не растут за Уралом (в Сибири), а появляются только на юге Дальнего Востока?

Answer 1

Широколиственные леса в Сибири не растут из-за высокой континентальности климата:

1. Большая амплитуда температур в году
2. Длительные низкие зимние температуры (их широколиственные породы не переносят)
3. Небольшое количество осадков

Answer 2

Why Broadleaf Tree Species Do Not Grow Beyond the Urals (in Siberia) and Only Appear in the Southern Far East?

The absence of broadleaf tree species beyond the Urals in Siberia and their presence only in the southern Far East can be attributed to several factors.

Climate and Environmental Conditions: The primary reason for the absence of broadleaf tree species beyond the Urals in Siberia is the harsh climate and environmental conditions. The Siberian region is characterized by a continental climate with long, cold winters and short, cool summers. This climate is not conducive to the growth of broadleaf tree species, which typically thrive in milder and more temperate climates. The southern Far East, on the other hand, experiences a more moderate climate, which is more suitable for the growth of broadleaf trees.

Geographical Factors: The geographical features of the Siberian region, including its vast expanses of taiga and boreal forests, also contribute to the absence of broadleaf tree species. The dominance of coniferous trees in these regions is a result of the adaptation of these species to the prevailing environmental conditions, including cold temperatures and acidic soils.

Historical and Evolutionary Factors: The historical and evolutionary development of plant species in these regions also plays a role. The geological history of Siberia and the Far East, including past glaciations and tectonic movements, has influenced the distribution of plant species. Over time, the unique environmental conditions and historical factors have shaped the flora of these regions, leading to the prevalence of coniferous trees in Siberia and the appearance of broadleaf tree species in the southern Far East.

In summary, the absence of broadleaf tree species beyond the Urals in Siberia and their presence only in the southern Far East can be attributed to the harsh climate and environmental conditions, geographical factors, and historical and evolutionary influences. These factors have collectively shaped the distribution of tree species in these regions.
