Multiple Nuclei Model

The multiple nuclei model was proposed in 1945 by C. Harris and E. Ullman. The model shows thahttp://www.blogger.com/img/gl.photo.gift cities may grow from not on CBD, but from several independent growth poles (nuclei).

The model shows that some urban functions exist in pockets because of the advantages of a particular site.

Hoyt's Sector Model

Hoyt developed the Burgess model, suggesting that urban settlements' land uses are modified by their relative accessibility to transport routes.He expanded on Burgess' five zones, adding another three, including outlying business districts and dormitory suburbs.

The Hoyt model was developed in 1939 by economist Homer Hoyt.

Burgess Concentric Zone Model

The Burgess Concentric Zone Model was created in the 1920s by American geographer E.W. Burgess.

Burgess divided cities into 5 key zones, with the CBD in the centre. he suggested that a city would develop its land use in all directions around the CBD.

Auckland can be modeled by the Burgess model.

Deforestation

Amazon Land Use

The Amazon has much mineral wealth, so mining is a key land use. Mining for ores such as iron occurs in open cast mines in areas where the mineral is found in a sufficient quantity. The forest is cleared and machinery is brought in to excavate, causing changes to natural ecosystems and pollution of the forest environment.

Varzea cultivation is a type of farming that takes place on the fertile floodplains of many rivers. As silt is regularly deposited on the varzea, the soils are very fertile. This means farmers can grow crops such as manioc and herd cattle here when water levels aren't too high.

The natural beauty of the Amazon rainforest and the unique biota found there have made this region an increasing important area for ecotourism. Visitors from places such as the USA and Germany enjoy admiring the scenery and learning about the customs of the native people. As a result, infrastructure development occurs and tourists facilities are built (eg - the Tropical Hotel in Manaus).

Human Use of the SIHC - Tourism

Tourism is a key use of the SIHC, based on the natural beauty of the landscapes in this region.

The relief and climate of the Southern Alps makes it ideal for skiing. The cold winter temperatures and snow in the Alps has resulted in the development of several top class skiing facilities, such as Coronet Peak and Treble Cone.

The glaciers to the west of the Alps, such as Fox and Franz Josef are also a popular tourist attraction, with people from all over the world coming to see them. Some tourists choose to fly over them in helicopters to admire the view.

Tramping is another popular recreational activity that attracts tourists from all over the world. There are many tracks in and around the Alps (eg- the tracks in Mt Aspiring National Park) that people come to walk and admire the natural beauty of the landscape.

Skiing has changed the environment in many ways. Ski resorts and facilities such as chairlifts have been built on the many ski fields. Queenstown has recently built an international airport allow siiers to fly directly to Queenstown. Some slopes have been re-contoured by blasting to improve skiing, altering the relief of the area.

The glaciers have resulted in the building of accommodation and facilities for tourists within the landscape, such as the Fox Glacier Tourist Park.

Tramping within the region has led to the development of tracks through the land. These can alter the physical environment and change the land's appearance. Rubbish left b y trampers can also change the land's appearance (visual pollution).

Volcanic Landscape - Maui, Hawaii

Climate - Maui's climate is warm and moist. Showers are common although usually short. High rainfall is contributed to by the volcanic mountains that make up the island, as trade winds blow moisture in from the sea and drive it up the slopes to cool and condense.

Soils - Soil is fertile, volcanic and often moist due to tropical showers, consisting largely of ash erupted from the island's two volcanoes. The free-draining soil is useful for farming, and is made use of for growing sugarcane and pineapples.

Relief - The landscape is made up of steep sided volcanic mountains which have been eroded by wind and rain. Step ravines run down the sides, directing water down to the flat plain and shoreline below.

Vegetation - The vegetation is largely tropical due to the high rainfall and warm, stable temperatures. At high altitudes, mosses and grasses grow up the sides of the volcanic hills.
