The influence of LUCC on water demand in the north slope of Tianshan Mountain

This paper analyzes the spatial distribution and change of domestic water in the economic belt of the northern slope of Tianshan Mountains, understands the influence of LUCC process on domestic water, and provides a scientific basis for sustainable utilization and management of domestic water in arid areas. In this paper, the conventional linear fitting method is used to analyze the temporal and spatial change trend of domestic water use and the impact of land use change on it in 1989-2017 in the northern slope of Tianshan economic belt. The results show that from 1990 to 2018, the area of urban and rural industrial and mining residential areas increased by 1734km², the population increased by 158.58 × 10⁴, the total domestic water consumption increased from 125 × 10⁶m³ in 1989 to 398 × 10⁶m³ in 2017, and the per capita domestic water consumption also increased rapidly, especially in urban areas. The spatial difference between per capita domestic water consumption and total domestic water consumption in the whole year is obvious. It can be seen that the LUCC process has an important impact on the change of domestic water consumption.
