Geography of Macau

From Wikipedia, the free encyclopedia

Macau is a city on the southern coast of China. It is located at the south of Guangdong Province, on the tip of the peninsula formed by the Zhujiang (Pearl River) estuary on the east and the Xijiang (West River) on the west. Macau is situated sixty kilometers west of Hong Kong and 145 kilometers southwest of Guangzhou, the capital of Guangdong Province. It is immediately adjacent to the Zhuhai Special Economic Zone.

The region comprises the Macau Peninsula and the islands of Taipa and Coloane. Macau was once an island but gradually a connecting sandbar turned into a narrow isthmus. Land reclamation in the 17th century made Macau into a peninsula, and a barrier gate was built to mark the separation between the peninsula and the mainland. Pre-colonial records show that Macau totaled only 2.78 km² but began to increase as a result of Portuguese settlement. Land growth has accelerated since the last quarter of the 20th century, from 15 square kilometers in 1972 to 16.1 square kilometers in 1983 to 21.3 square kilometers in 1994. Macau's size has gradually increased as result of continued land reclamation, especially on Taipa and Coloane. In 2000, the total land area was approximately 23.6 km². There is a 0.34-kilometer-long border between Macau and mainland China and a forty-kilometer-long coastline.

[edit] Location, Size, Border, and Coastline

Location: Eastern Asia, bordering the South China Sea and China

Geographic coordinates: 22°10′N 113°33′E

Area:
total: 21 km²
land: 21 km²
water: 0 km²

Land boundaries:
total: 0.34 km
border city: Zhuhai, Guangdong Province 0.34 km
Coastline: 40 km
Maritime claims: not specified

[edit] Topography

Terrain: generally flat
Elevation extremes:
lowest point: South China Sea 0 m
highest point: Coloane Alto 174 m

Macau has generally flat terrain resulting from extensive land reclamation, but numerous steep hills mark the original natural land mass. The modern high-rise skyline of Macau obscures much of the hilly landscape. The Macau skyline both defines and obscures its topography.

The Macao Peninsula is narrow in shape but varies in terrain:

The East Ocean Watching Hill, West Ocean Watching Hill, Persimmon Hill, Lotus Hill, Luosi Hill and Qingzhou Hill are famous scenic spots in Macao. The Persimmon Hill used to be a fortress surrounded by stone walls. The fortress, which resembles an imposing European castle, is now a tourist attraction. Standing on the Persimmon Hill, one gains a panoramic view of both Macao and the nearby Zhuhai.

The West Ocean Watching Hill, a tranquil scenic spot, is noted for the cathedral and the bishop's mansion on its top. Viewed from the Nanxi Bay in the distance, particularly against the evening glow, the cathedral and the mansion stand in their full splendor. From the top of the Persimmon Hill, one sees the Nanxi Bay and the high rise buildings there as well as the sea and the sea - spanning bridge.

[edit] Climate

Subtropical; marine with cool winters, warm summers.

The climate is subtropical and is hot and humid, with an average year-round temperature of 25°C and temperatures exceeding 30°C from June to September. Temperatures rarely fall below 14°C (the average for January and February). There is about 2,030 millimeters of rainfall annually.

Macau is exposed to tropical storms originating from the southern Pacific Ocean during the summer. Major destruction occurred in September 1874, when a devastating typhoon hit Macau and high seas swept across the low-lying area of the peninsula.

Prevailing winds and weather types change follow the monsoon pattern. It is warm and moist when the southeast and southwest winds coming from Pacific Ocean, and typhoons are relatively common during summertime; and is dry and slightly cold when the north winds coming from Siberia or the northern part of Mainland China.

During the transition period from northeast monsoon to southwest monsoon (March and April), the weather is moist and foggy. It is Macau's spring season. Summer is from May to September, when the southeast and southwest monsoon prevailing. It is rather hot and rainy. The weather in autumn (the end of September and October) is sunny and warm, when the southwest monsoon withdrawing gradually and the northeast monsoon advancing south. Winter is from November to February next year, when the northeast monsoon prevailing.

[edit] Natural Resources

Negligible. In the past, large amounts of granite were extracted from Macau's hills for use as building material.

[edit] Fresh Water

Relying on the water supply of Xijiang River, Macau is at present suffering its worst ever crisis of salinity in freshwater during this year's dry season which takes place in late winter and early spring time. The salinity level of freshwater has recently aggrandized far above the standard set up by the World Health Organization or WHO. By the end of 2007, Macau will be able to solve the problem of tap-water supply with relatively high level of salinity after the completion of the Ping Gang project. This project is aimed at shift the intake of raw-water on the Xijiang River 20 km upstream in order to give a wide berth to the salt tide in the province of Guangdong.

[edit] Land Use

No arable land, pastures, forest, or woodland. Because of this deficiency, Macau's people traditionally have looked to the sea for their livelihood.

arable land: 0%
permanent crops: 2%
permanent pastures: 0%
forests and woodland: 0%
other: 98% (1998 est.)

[edit] Environmental Factors

Dense urban environment.

Geography - note: essentially urban; one causeway and two bridges connect the two islands of Coloane and Taipa to the peninsula on mainland
