What is the main terrain of Jiayuguan?

Located in the middle of Hexi Corridor in Gansu Province, on the western edge of Jiuquan Basin, with Qilian Mountain in the south and Mazong Mountain in the north, it is a city named after Jiayuguan, the starting point of the western end of Wan Li Great Wall in Ming Dynasty. The north-south boundary of the city lies between Manjusri Mountain and Yushugou Mountain. Between the two mountains is a canyon 15 km long, which is the "first pass in Hexi" and a battleground for military strategists. The terrain inclines from southwest to northeast, with an average elevation of 1500- 1800 meters, and Manjusri Mountain is 2228 meters above sea level. Montenegro is the highest peak in the city, with an altitude of 2799 meters.

Jiayuguan City was built in the fifth year of Hongwu in Ming Dynasty (A.D. 1372), with a history of more than 600 years. At first, we only talked about cities, and there were no buildings. Later, it was built in the Ming Dynasty. At that time, the construction of Jiayuguan consumed a lot of manpower and material resources. It was really not easy to build such a magnificent Guancheng under the condition of poor ancient building equipment. Then, we deduced some touching stories, such as building bricks, transporting stones on ice, goats carrying bricks and hitting stones. Jiayuguan, an ancient city in the past, has now developed into a new city in the northwest: majestic blast furnaces point to the blue sky, huge buildings are scattered, rows of poplars block the sun, steel cities are shining in front of us, and the gliding base is unprecedented ... The Great Wall of Wan Li, which symbolizes the spirit of the Chinese nation, starts from Shanhaiguan in the east and reaches Jiayuguan in the west. At this point, I finally drew a beautiful and solid full stop here.

From 65438 to 0958, with the construction of jiuquan iron and steel Company, a national key project in the First Five-Year Plan, it gradually developed into a new industrial city, an open city for tourism, and the largest iron and steel joint enterprise base in northwest China, and was known as the "Northwest Steel City". The city is 40 kilometers long from east to west and 35 kilometers wide from north to south, with a total area of 2935 square kilometers. The urban area is 60 square kilometers, and 27 square kilometers have been built. The city has jurisdiction over six sub-district offices in Wuyi, Xinhua, Qianjin, Shengli, Jianshe and Jingtieshan mining areas, and three townships in Jiayuguan, Xincheng and Manjusri. The total population is 6.5438+0.3 million. There are Han nationality, Hui nationality, Mongolian nationality, Tibetan nationality, Manchu nationality, Dongxiang nationality, Yugur nationality, Korean nationality, Zhuang nationality, Tu nationality, Baoan nationality and Uygur nationality 12, among which ethnic minorities account for 3. 47% of the total population. Jiayuguan is a city dominated by immigrants, with residents from various provinces and regions in China, mostly from Shandong and Northeast China.

Industry, tourism and agriculture are the three pillars of Jiayuguan's economic development. There are more than 80 industrial enterprises above villages and towns in the city, including Jiuquan Iron and Steel Company, the largest iron and steel joint venture in northwest China.

Jiayuguan City is an important tourist city on the ancient Silk Road. There are the famous Jiayuguan Gate Tower, the first pier of Wan Li Great Wall, the hanging Great Wall, the Fengdun site of Ming Great Wall, the Great Wall Museum, the mural tomb of Wei and Jin Dynasties in Xincheng, the Qiyi Glacier, the desert Gobi scenery and the Manjusri Mountain Grottoes.
