“…The Representative Concentration Pathways (RCPs) mentioned in the Fifth International Coupled Model Comparison Program were used to study soil conservation. Climate-induced changes in precipitation could offset the soil and water conservation promoted by vegetation growth (Liu et al, 2021). Moreover, the variation trend of SCS under different emission scenarios was consistent with the change rule of rainfall and temperature, and the maximum increase was observed under high-emission scenarios (Feng et al, 2020).…”

Land use pattern optimization is an effective approach for sustaining soil conservation service (SCS) under the influence of climate change and anthropogenic activities across the Loess Plateau of China. However, current studies establish ecological protection scenarios (EPSs) for land-use optimization based on the transfer matrix of EPS alone, which ignores the important role of scientific intervention by human beings on land-use patterns. To fill this knowledge gap, the Wuding River watershed was employed as the research object, and land use under three EPSs was simulated according to the transfer matrix, dry-wet zoning, slope, and soil and water loss zoning. The quantity of SCS and its spatial flow and benefit under different climate scenarios were then simulated and compared with those under natural development scenarios (NDSs). SCS was found to decrease due to the expansion of urban areas and agriculture under the NDSs and increase under the EPSs relative to the NDSs. In addition, under the EPSs, SCS restricted to dry-wet zoning exhibited no significant advantage over those without additional constraints. However, when complex constraints, such as dry-wet zoning, slope, and soil and water loss zoning, were combined, SCS was significantly improved in areas with large topographic fluctuations. Further, compared with that in 2000–2020, the benefit of SCS in future scenarios displayed an increasing trend in the direction of the mainstream. Owing to the cumulative benefit, when the spatial flow of the SCS upstream decreases with urban expansion, the benefit for the downstream area, which is provided by land-use optimization, will decrease. Overall, our findings provide a framework for land use optimization by incorporating ecosystem service flow, ultimately facilitating land management, ecological restoration, and soil erosion prevention.

“…The direct impact of natural factors on forest ecological functions was evident in the wide variability of vegetation types, forest biomass, community structure, and naturalness concerning temperature, precipitation, and elevation. The water and thermal resources in the YRB exhibited a decrease from south to north, with more pronounced characteristics as more in the southeast and less in the northwest [40]. We found it becomes evident that annual precipitation and average temperature across counties showed an upward trend during 2004-2018.…”

“…To capture the influence of factors on FEF under different spatial and temporal conditions, we used the Geographic temporal weighted regression (GTWR). GTWR integrates the temporal and spatial information into the weighting matrix, and explores the heterogeneity of driving factors in the temporal and spatial dimensions [40]. It can also be used to handle panel data, leading to results closer to the actual situation.…”

Human activities (e.g., exploitation, utilization, and conservation) exert substantial impact on forest ecological functions (FEF). The human influence on FEF significantly varies across developmental stages, which are attributed to the temporal and spatial in nature. This study evaluates some notable FEF indices (FEFI) in the 448 counties within the Yellow River basin (YRB) using panel data from the Seventh to Ninth National Forest Inventory. Data analysis involves employing the residual trends, geographical and temporal weighted regression. Results indicate that, firstly, the overall forest ecological function in the YRB is moderate to inferior, with superior FEF in counties endowed with more natural forest resources. Afforestation demonstrates a short-term improvement, but its effectiveness diminishes over time. Secondly, the positive spatial correlation is stronger among counties, characterized by both high-high and low-low agglomeration effects. Scattered planting, simple stand structure, and concentrated harvesting of forests at the identical stand ages hinder the formation of complex and large-scale FEF agglomerations. Thirdly, significant spatial-temporal differences exist in the impact of human activities on FEF. In the upper reaches of the basin, increased vegetation coverage through agricultural and forestry production benefited FEF, however, some over-exploitation of forests and grasslands is observed there. In the middle reaches, the economic development, expanding population and the greening activities help to improve FEF effectively, but excessive water using in agricultural production brought more difficulties to FEF improvement. In the lower reaches of the basin, improved wastelands and forest protection positively influence FEF. This study recommends that county governments should prioritize forest management with multi-species and multi-layered complex forests. Each county should define its position in regional development and ecological protection, considering the potential impacts on neighboring regions. This holistic approach promotes more effective integrated regional management.
