“…We found that ESs are mainly low-low spatial matching areas, and are concentrated in the Desert Areas. Therefore, we should protect the ecological environment in the southern Qilian Mountains, strengthen regional ecological management, and maintain the integrity of the ecosystem 40 , 41 . For the core area of Qilian Mountains, we should strengthen the protection of the Qilian Mountains glacier and water conservancy ecological function area in the future.…”

To achieve the best management of the ecosystem and sustainable socioeconomic development, it is crucial to clarify the matching relationship between the supply and demand of ecosystem services (ESs). Four types of ESs were chosen for the Hexi region in this study: food supply, carbon sequestration, water yield, wind erosion control and sediment retention. We assessed the supply–demand and matching relationships of different ESs using the Integrated Valuation of Ecosystem Service and Tradeoffs (InVEST) model, the ESs supply–demand ratio and the four-quadrant model. Moreover, we also analyzed the supply–demand ratio of integrated ESs and their cold spots. The findings suggest that (1) from 2000 to 2020, the average supply of food supply, carbon sequestration, water yield, wind erosion control and sediment retention increased by 44.31 t/km2, 128.44 t/hm2, 14,545.94 m3/km2 and 0.14 kg/m2 respectively, which showed a spatial pattern of “high in the southeast and low in the northwest”. The average demand for food supply and carbon sequestration increased by 1.33 t/km2 and 0.32 t/hm2 respectively, while the average demand for water yield and wind erosion control and sediment retention decreased by 2997.25 m3/km2 and 1.19 kg/km2 respectively. The spatial distribution is consistent with the layout of population density, production and residential areas, and fragile ecological areas. (2) The supply–demand ratio of food supply, carbon sequestration and water yield is greater than 0.095, which is in a state of oversupply, and the supply–demand ratio of wind erosion control and sediment retention is less than 0, which is in a state of shortage; all ESs are mainly in low-low spatial matching areas, mainly concentrated in the desert areas of the northwest in the Hexi region. (3) The supply–demand ratio of integrated ESs increased by 0.024, and the proportion of cold spots and sub-cold spots was more than 50% and concentrated in the northwest, while hot spots and sub-hot spots accounted for only about 16%, mainly distributed in the southern Qilian Mountains and some oasis areas.

“…These studies confirm patterns of human-nature interaction at a particular time (Feng et al 2019, Wu et al 2020b), but studies of human-nature interactions at long time scales and in stages are lacking. Their solution often requires holistic approaches, which can simultaneously incorporate human and natural components, combine modern and palaeoclimatic data (Li et al 2018), and reduce regional and cross-scale environmental impacts (Wei et al 2022), to construct long time series of human and nature evolutionary processes. These approaches thus avoid unintentional impacts on time scale differences.…”

Located in the eastern section of the ancient Silk Road, the Hexi Corridor is a crucial area where eastern and western civilizations met. Previous studies mainly explore human-nature interactions at a particular period, and there is a lack of phased human-nature interaction studies at long time scales. Here we present the relationships and patterns of interaction between humans and nature in the region over the past 10 000 years and distinguish the stages and mechanisms of interaction, which can be divided into three periods in the region. 10 000–4000 a BP is a period of weak interaction when human activities and natural processes are primarily non-interactive. The evolution of culture advances in its way rather than by environmental changes, and those early cultures do not strongly impact the natural environment. During 4000–2000 a BP, climate change becomes the dominant factor in human adaptation, mitigation, and migration in the region, and extreme short-term changes often impact the social system, intensifying the impact of nature on humans. Therefore, it is a strong interaction period (nature domination). From 2000 to 0 a BP, humans dominate environmental change manifested by surface processes, lake evolution, and regional water resource changes. At the same time, environmental change can backfire on humans, causing a series of social crises. Overall, it is a strong interaction period (human domination). We propose a Hexi model, a weak interaction—strong interaction (nature domination)—strong interaction (human domination) model, validated in other regions of the world for long time scale human-nature interactions.
