Analysis on the characteristics and causes of natural landscape in Xinjiang.

The geographical location and topographical features of Xinjiang lead to the climate in Xinjiang being characterized by drought, which in turn leads to the formation of a desert-dominated natural landscape in Xinjiang, which shows that the natural environment is a whole, and various factors restrict and influence each other. At the same time, human beings are the product of natural environment, and environmental characteristics will also affect human activities. The arid natural environment leads to the population and cities mainly distributed in oases and inland rivers with abundant water resources, and at the same time, some excessive human behaviors will also destroy the ecology and lead to environmental deterioration. Human beings and the environment should live in harmony and develop together.

The melons and fruits in Xinjiang are especially sweet and brightly colored. This is because Xinjiang has enough heat in summer. Because of the lack of clouds and precipitation in the air, the daytime light is strong, which is beneficial to the coloring of fruits and vegetables, and at the same time, the photosynthesis is strong during the day, which can accumulate a lot of sugar. At night, the temperature drops rapidly, the temperature is low, and the respiration of crops is weak, which also reduces the consumption of sugar accumulated during the day. Therefore, due to the large temperature difference between day and night, fruits and vegetables in Xinjiang are particularly sweet. Similarly, Xinjiang has become an important long-staple cotton producing area in China because of its rich light and heat resources, scarce precipitation and relatively stable irrigation water sources.

The stable irrigation water source benefits from the ancient water diversion project in Xinjiang-Karejing. (Look at the picture) The water in Karez comes from the area with rich groundwater in the foothills. At the foot of the mountain, due to the infiltration of mountain meltwater, groundwater is rich. Smart people in Xinjiang started from the foothills, dug shafts along the sloping terrain, and then dredged and excavated underground culverts by vertical propulsion, leading the gurgling spring water to the edge of the basin, thus maintaining the survival of the oasis. Because the canal is below the surface, it effectively avoids a lot of evaporation caused by climate drought, makes full and effective use of limited water resources, and enables Xinjiang people to thrive on the edge of this vast desert.
