Question

Human Adaptation of tropical monsoon region?In brief

Answer 1

Human's Activities in Tropical Rainforest

The natural environment influences man's use of tropical rainforest. The impact of human's activities to the natural environment is also very vital. They counteract to modify the natural environment.

A. Possibilities influence man's use of tropical rainforest

(1) The climate of tropical rainforest

The temperatures of tropical rainforest are high, the annual temperature range is under 3℃ in inland and 1℃ on the coast. The sun is always high in the sky. It reflects the lack of seasonal change. There is a long-growing season. Moreover, the annual rainfall usually exceeds 2000 mm and most afternoons it has heavy shower. This is due to the convergence of the trade winds at the ITCZ (Inter-tropical Convergence Zone). It forces the warm, moist air to rise in strong convection currents. Tropical rainforest has high solar radiation, all-year growing seasons, heavy rainfall, and a constant moisture budget surplus. The leaf litter is decayed rapidly and the nutrients are recycled between the biosphere and soil.

(2) Shifting agriculture

The vegetation influences the man's use of tropical rainforest. Humans find that it is not sufficiency place for them to have activities. So they cut and burn the trees to obtain the new land. The practice of shifting farming involves five steps. Firstly, the farmers select a site where is an area of gently sloping land and well-drained surface is preferred since too much water retention will cause root crops to not in the ground.


B. Impact of human activities to the natural environment

The impact of human's activities to the natural environment is very large, because it may influence in the atmosphere, the hydrosphere, the lithosphere and the biosphere.

Because of the population explosion, it intensifies all types of human activities in the tropical rainforest (TRF). Extended and large areas of TRF are used. It increases the scale and rate of deforestation in order to create the new land for the human beings. Therefore, the negative impact on the TRF ecosystem is found.

(i) Human impact on atmosphere.

Because of the burn and slash farming, human disturbs carbon and oxygen balance in the atmosphere. Originally, plants may release oxygen and absorb carbon dioxide. However, after the process of deforestation, it reduces the production of oxygen and marines oxygen depletion by burning
