How to evaluate the documentary Hexi Corridor?

I'm from Jiayuguan, and my hometown is Wuwei. My father has been traveling in Hexi Corridor for a long time. I am familiar with this piece of music. To tell the truth, I can see the different characteristics of Hexi Corridor. Gobi, snow-capped mountains, grasslands and deserts are all very touching. The whole documentary tells a good story about the whole history, but the development after liberation is not well described or described. The state has not paid attention to it for a long time, and the provincial government has not acted. This is not big. The long-term development of the western region is almost out of reach with Gansu. The whole Hexi Corridor is simply divided into three cities: Wuwei, Zhangye and Jiuquan. These three cities have the largest population, large scale and high level, but agriculture has been the mainstay since ancient times, with less cultivated land per capita and some lack of water resources. Since liberation, the development has been quite slow and the progress has not been great. Agriculture is rough and crazy, and it is irrigated by the snow water diversion canal in Qilian Mountain. Due to the large amount of evaporation, it is not fully utilized and the water resources are insufficient.

For example, my hometown Wuwei, according to the previous generation, the nearby mountains are still green, but they have been bare since I can remember. Over-exploitation of Shiyang River, an important river in Wuwei, has significantly reduced water resources and destroyed ecology. The most direct impact is the collapse of the ecosystem in Minqin area in the lower reaches of Shiyang River, and the desertification is serious. More than a decade ago, when there was a strong wind in Minqin, sandstorms could blow to Beijing. Since the frequent occurrence of sandstorms in Beijing, the central government has begun to pay attention to it, focusing on the management of Minqin. At present, the struggle between man and desert is still very severe. After talking about the three agricultural cities, let's talk about the three industrial cities mentioned in the documentary, Yumen Petroleum, Jiayuguan Iron and Steel and Jinchang Nickel, which are all derived from Jiuquan and Wuwei, and are the only development of Hexi Corridor after the founding of the People's Republic of China. The present situation is that Jinchuan Company has the best development, but the wine is just unsustainable and Yumen is gone. Yumen is gone, which is the result of relying solely on heavy mining industry, single development form and serious dependence on resources. The documentary describes Yumen because he is the cradle of China's oil industry. But now that the oil is gone, the excavation is completed. As a result, Yumen Petroleum Administration Bureau100000 employees and their families moved out of Yumen as a whole, Yumen disappeared and there was no city. The original site is a dead city. Jiayuguan was established on the basis of jiuquan iron and steel Limited Liability Company located in the west. There is no technology, just producing crude steel coils. Everyone knows the current steel market. Jinchang is the best, but nickel will be dug in the future. The present of Yumen may be the future of Jiayuguan and Jinchang.
