Abstract:

A thorough analysis of the spatiotemporal patterns and relationships between water conservation functions and human activities in arid and semi-arid regions is a necessary prerequisite for the scientific implementation of regional ecological restoration and water resource management. Employing a combination of the Human Footprint and InVEST models, quantitative assessments were conducted on the intensity of human activities and water conservation functions in the Hexi region. Additionally, spatial relationships between human activities and water conservation in the Hexi region were analyzed using bivariate Moran's I and other methods.The research findings indicate that there has been a trend of increasing human activity levels from 2010 to 2020, with an overall pattern showing higher activity in the southeast and lower activity in the northwest. The average water conservation capacity per unit area during the period from 2010 to 2020 was 8.64 mm. It showed an upward trend from 2010 to 2015 but declined from 2015 to 2020. The overall spatial distribution displayed a pattern of higher conservation capacity in the south and lower in the north. The bivariate Moran's I index for 2010, 2015, and 2020 were 0.292, 0.277, and 0.348, respectively, indicating a significant positive spatial correlation between human activities and water conservation service functions.
