Altitudinal zonation

From Perupedia

Jump to: navigation, search

Altitudinal zonation or Altitudinal variation is the creation of zones to explain the different characteristic climates at different elevations. The different zones can support different vegetation, agriculture, etc. As one moves to higher elevation points one enters different altitudinal zones. Founded by a geographer named Alexander von Humboldt. Humboldt is also credited with Environmental Lapse Rate - the measure of how many degrees temperature drops as you move to higher elevation. By his delineation (in 1817) of "isothermal lines", he at once suggested the idea and devised the means of comparing the climatic conditions of various countries.

Introduction

Saturated adiabatic lapse rate is usually near +4.9 °C/1,000 m (+2.7 °F/1,000 ft or +1.51°C/1,000 ft) at temperatures above freezing. [1]

In the altitudes between 3,400 meters (11,000 feet) and 4,500 meters (15,000 feet) some of the most extreme examples of adaptations can be found. At altitudes below 3,400 meters (12,000 feet) the daily temperature fluctuations are less extreme, the average daily temperature steadily increases, and the growth forms and ecology of the Dendroseneico reflect the increased influence of biotic factors (such as competition for light) over abiotic factors (such as nightly frost). [26]

Jade Dragon Snow Mountain, 13 peaks

It is the glacier nearest of the Equator on the North Hemisphere. The landmarks 4,506 m and 4,680 m at the end of the glacier can be achieved through the cable car from Ganhaizi (tibetan for dry lake, a grassland with conifers at 3,400 m). The mountain desert begins around 4,000 m. The Three Parallel Rivers of Yunnan (Unesco World Heritage Site) encompasses the watershed areas of the Yangtse (Jinsha), Mekong (Lan Cang) and Salween (Nujiang) rivers and is the joint of the Palearctic ecozone and the Indomalaya ecozone.
