At that time, Phoenix was called Huzdo or Phoenix. The former means "hot place" in Navajo, and the latter is West Apache. Phoenix is located on both sides of Ganyan River all year round. It covers an area of 839 square kilometers and has a population of about 1.57 million. This is a prehistoric cultural site. Established in 188 1. 189 1 year railway. 19 12 was designated as the state capital. 19 1 1 year to build Roosevelt dam and reservoir and develop irrigated agriculture. After the Second World War, cities developed rapidly and industries rose. The economy is dominated by manufacturing, followed by agriculture, mining, logging and tourism. Salter Valley produces cotton, vegetables and fruits, which is the main irrigated agricultural area. Quanzhou industrial center, the industry has aluminum smelting, cotton ginning, aircraft parts, computers and so on. Here is the intersection of national highway and interstate highway, with convenient railway and air transportation. Tourism is mainly based on winter shelter and recuperation, including desert botanical garden, Papago Park and ancient Indian ruins. There are several universities, such as Phoenix College, Grand Canyon College and Arizona State University. The main buildings are the State Capitol and the Phoenix Civic Square.

[Edit this paragraph] History
▲ Native American period
Around 700 AD, the Indian Huohuokan civilization developed in the area where Phoenix is located today. They dug an irrigation canal about 65,438+035 miles (265,438+07 kilometers) and turned it into cultivated land. Some irrigation canals are located in the same place as the Hayden-Rhodes aqueduct in today's Central Arizona Project Canal.
It is believed that from 1300 to 1450, drought and fierce floods led to the disappearance of Hohokam civilization. There are also views that their extinction is related to the invasion of Pima people living near Yanhe River and Gila River and Tohono Odham people in southern Arizona.
Although Spanish and Mexican explorers already know where Phoenix is now, their influence is limited to southern Arizona. At that time, the Yanhe river basin area still maintained its original appearance. The local Akimel O 'odham people, considered as descendants of Hohokam, have long lived along the Gila River and are adjacent to the Tohono O 'odham people and Maricopa people.
▲ Before the city was built
1867, Jack Swaling Road in Fort Weicon passes through here. When resting at the foot of Baiguan Mountain, I found this place very suitable for farming. Except for less precipitation and no irrigation facilities, the terrain and climate are ideal. On the basis of the former site of Huohokan civilization, a series of new irrigation canals in Swelling have effectively solved the irrigation problem. As a result, a new settlement gradually formed about 4 miles (6 kilometers) east of today's Phoenix. Not far from the southeast is Hayden Ferry, which later developed into today's Tempe.
Swell originally named this place Swelling's Mill, and later renamed it Hell Mill and Mill City. Now it's called the East Phoenix. Swelling, an American veteran, had hoped to name this place Stone Wall in memory of General Jackson, and some people suggested naming it Salina. But neither of these names is suitable for the name of the settlement, so Lord Darrell Dupa finally named this place Phoenix, which means a city reborn from the ruins.
Yawapai County, which was in charge of the Phoenix area at that time, officially named the area Phoenix, and established the constituency 1868 on May 4th. The first post office in Phoenix officially opened on June 5th, 1868, and Jack Swelling became the first postmaster. With the continuous expansion of the city scale, the establishment of offices has been put on the agenda. 1870,101On October 20th, the residents' assembly decided to buy a 320-mu (1.3 square kilometer) office, which is now the location of the downtown business district. 1871February 12, Phoenix broke away from Yawapai County and established the sixth local council in Arizona, namely maricopa county. In the same year, the county held its first election, and Tom barnum was elected as the county magistrate. Barnum's two competitors, John A. Chenowth and Jim Favorite, had a gun battle in the election, and Favorite was killed in the gun battle, so Chenowth withdrew from the election [5].
1870, a lot of land was sold at an average price of $48. 187 1 year, the first hall and the store started business respectively. On September 5th, 1872, public schools opened in CCBA court for the first time. 1873, a primary school was built on Central Avenue (now Central Avenue). In the same year165438+1October 19, Florence Land Management Bureau registered the land in Phoenix; 1872 February 15, Prescott Land Management Bureau issued the first official announcement. 1874 10 in April, President hiram grant signed the public land holding certificate in the area where Phoenix is now located. The value of the entire Phoenix CCBA is $550, while the downtown price is $7 to 1 1 per movie. Soon after, a telegraph office, sixteen salons, four dance halls and two banks opened respectively.
▲ After the city is completed,
188 1 year, Phoenix has formed the initial government and office system. 1 1 The local Council passed the Phoenix Charter Act and decided to establish a mayor-parliamentary government. 1881on February 25th, John C. Fremont signed the bill as the local governor. At that time, the population of Phoenix was about 2,500. On March 3rd, 188 1, Phoenix held its first election. Judge John T. Alsap defeated James D. Monihon and was elected as the first mayor by 127 to 107. 1888 At the beginning of the year, the municipal government moved into the new town hall, which is located in the current bus hub in the city center. It is also the temporary office of Arizona local government after it moved from Prescott to Phoenix in 1889.
1880s, the construction of railway became the first opportunity for Phoenix's economic development. Since then, a large number of goods have entered Phoenix by railway, and Phoenix has also become a commodity distribution center for obtaining things. 1888165438+1On October 4th, the Phoenix Chamber of Commerce was established.
189 1 year, the railway runs through,191year, the Roosevelt dam and reservoir were built, and the irrigated agriculture in this state rose. Followed by the development of nearby metal mines. 1893, Fenghuang also built a tram system to replace the previous carriage line.
▲ 20th century
1902, President theodore roosevelt signed the National Reclamation Act, which allowed the construction of dams on rivers in the west for reclamation. Phoenix residents benefited from the bill, and on February 7 1903, the Yanhe River Utilization Association was established to manage water resources and generate electricity. At present, this institution still exists and becomes a part of Yanhe development project. 1912 February 14, during President william howard taft's administration, Arizona officially joined the United States, and Phoenix became the capital of Arizona.
19 13, the political system of phoenix changed from mayor-parliamentary system to parliamentary system-manager system, becoming one of the earliest cities in the United States to carry out political system reform.
In World War II, Phoenix quickly changed from a logistics center to a new industrial city relying on military industry. Luke Field Air Base, Williams Field Air Base, Falcon Field Base and Haider Training Base have brought many new people to Phoenix.
After World War II, the industry developed rapidly and the urban population surged. A fire in 1947 destroyed almost all trams, so Phoenix is faced with a dilemma of rebuilding the tram system or adopting buses. Finally, Phoenix decided to develop public transportation system until private cars became the main form of urban transportation.
In the 1950 s, more than100,000 people lived in Phoenix, and thousands more lived in communities around the city. At that time, Phoenix had about 65,438+048 miles (238 kilometers) of built roads and 65,438+063 miles (262 kilometers) of dirt roads.
The population of the western, northern and surrounding areas of Phoenix increased rapidly in the late 20th century and early 20th century.
[Edit this paragraph] Geography
Phoenix is located at 33 31'42 "north latitude and112 4' 35" (33.528370,-12.076300) gr/kloc-west longitude. Phoenix is located in central Arizona, which is also called Salt Valley or Sun Valley. The average elevation of Phoenix is 1, 1 17 feet (340 meters), and it borders the Sonoran Desert in the south.
The salt river runs through Phoenix from east to west. Unless the upstream dam opens to release water, the salt river will almost dry up. Tempe City has built two rubber dams, so Phoenix has an artificial lake, commonly known as Tempe Lake. When the upstream dam discharges water, the rubber dam can completely deflate to achieve the purpose of flood discharge.
Phoenix is surrounded by mcdowell Mountain in the north, White Tank Mountain in the west, Superstition Mountain in the east and Sierra Estella Mountain in the south. There are Phoenix Mountain and Nanshan Mountain in the city. As of 2005, the western and northern boundaries of the Greater Phoenix area have exceeded the above range, while the southern part has been connected with Binar County. According to the US Census Bureau, the current area of Phoenix is 475. 1 square mile (1 230.5 square kilometer), including 474.9 square miles (1 229.9 square kilometer) of land and 0.2 square mile (0.6 square kilometer) of water.
The official name of Metropolitan Statistical Area (MSA) is Phoenix-Mesa-Scottsdale Statistical Area, which is the 13 largest city in the United States. The data of 2000 census is 325 1876, including maricopa county and Binar counties. Other cities in MSA include Mesa, Scottsdale, Glendale, Tempe, Chandler, Gilbert and Pioria. It also includes other small communities, such as Cave Creek, Queen Creek, Buckeye, Goodyear, Fountain Hills, Litchfield Park, Anthem, Sun Lakes, Sun City, Sun City West, Avondale, Surprise, El Mirage and Tolleson. Ahwatukee community is also a part of Phoenix, but it is almost completely separated from the rest of Phoenix by Nanshan.
Like most other places in Arizona, there is no daylight saving time in Phoenix. 1973, Governor Jack Williams proposed to the U.S. Congress that energy consumption at night would increase because the frequency of using refrigerators at night was higher than that in the early hours of standard time. He also pointed out that if daylight saving time is adopted, more lighting equipment will be used in the early morning, and it is not safe for children to go to school before dawn. The only place in Arizona where daylight saving time is used is the Navajo Nation in the north, because it can be synchronized with the tribes in other states.
▲ climate
Phoenix has a dry climate, and the annual average temperature ranks first among major cities in the United States. Worldwide, only some cities near the Persian Gulf, such as Riyadh in Saudi Arabia and Baghdad in Iraq, have higher annual average temperatures than Phoenix. On average, the temperature in Phoenix exceeds 100 degrees Fahrenheit (38 degrees Celsius) for 89 days every year, almost all the time from June to September. 1On June 26th, 990, the temperature in Phoenix reached 122 degrees Fahrenheit (50 degrees Celsius), the hottest day since meteorological records began [14]. The lowest temperature at night in summer often exceeds 80 degrees Fahrenheit (27 degrees Celsius), the average temperature at night in July is 83 degrees Fahrenheit (28.3 degrees Celsius), and in August it is 84 degrees Fahrenheit (28.8 degrees Celsius). The highest and lowest temperature in history is 96 degrees Fahrenheit (36 degrees Celsius), which appeared on July 15, 2003.
The dry desert air makes the climate in early summer acceptable, but the water vapor brought by the monsoon around July will greatly increase the humidity in the air and make people feel stuffy. In most cases, the winter in Phoenix is warmer.
Phoenix can receive sunlight on average 85% of the time, but the rainfall is less. The average annual total precipitation of Phoenix Tiangang International Airport is 8.3 inches (265,438+00 mm). The maximum precipitation is in March, about 1.07 inch (27mm). The smallest in May is about 0.09 inch (2 mm). Although thunderstorms can occur all year round, most of them occur from July to mid-September, accompanied by humid air blowing from California Bay. Thunderstorms may be accompanied by hail, and even in rare cases, tornadoes. When the winter storm moves inland from the Pacific Ocean, it may cause heavy rain, but this is not common. It is often foggy in winter.
Generally speaking, in Phoenix, there are only five days in a year, and the weather temperature will drop below 0 degrees Celsius [16]. Long-term statistics show that the first frost usually appears in 12, 15, and the final frost appears in 1. However, these data may not fully summarize the situation of the whole city, and the climate changes greatly with impassable terrain and altitude. Generally speaking, frost can be seen on the edge of the city, but it is difficult to see winter frost near the airport. The earliest first frost appeared in 1946 1 1.3, and the latest final frost appeared in1.945 on April 4th. The historical lowest temperature in Phoenix appeared on 19 13 65438+200310.7, which was 16 degrees Fahrenheit (-8.8 degrees Celsius).
It seldom snows in the Phoenix area. The first recorded snowfall occurred at 1896, and the snowfall exceeding 0. 1 inch (0.25 cm) only happened next. The maximum snowfall occurred in 1 937,65438+1October 20th to 65438+1October 2nd1,and the snowfall reached1to 4 inches (2 to10cm). The snow didn't melt completely until four days later. In addition, 1933 1 on October 20th, there was a snowfall of1inch (2.5cm). 0.5 inch (1 cm) snowfall occurred on February 2, 939. The last heavy snowfall occurred from 1 February 20th, 990 to1February 20th, with a snowfall of 0.4 inches (1cm). In addition, snowfall occurred in1917 March 12,1919 June 165438+ 10/28 October and10. On June 27th, 2007, snow fell in most parts of Phoenix, including Mesa and Tempe, which caused the temperature to drop by 20 degrees Fahrenheit.
