“…The larger the slope was, the more easily it caused soil and water movement, forming accumulation and loss, while a smaller slope can inhibit water production in the basin to a certain extent and play the role of soil and water conservation [46]. Temperature was negatively correlated with ESs, which was consistent with the research results of [47]. Temperature affects water yield and its coverage to a certain extent, and then affects ESs.…”

Uncovering the trade-offs and synergy relationship of multiple ecosystem services (ESs) is important for scientific ecosystem management and the improvement of ecological service functions. In this study, we investigated the spatiotemporal changes of four typical ES types (i.e., water yield (WY), carbon storage (CS), soil conservation (SC), and habitat quality (HQ)) from 2001 to 2020 in the Han River Basin (HRB). Meanwhile, the trade-offs and synergies between paired ESs and the socioecological drivers of these ESs were further explored. The results showed that grassland, cropland, and bare land decreased by 12,141.3 km2, 624.09 km2, and 22.1 km2 during the study period, respectively, which can be attributed to their conversion to forests in the HRB. Temporally, the WY, CS, and SC all showed a continuously increasing trend. Spatially, WY and HQ exhibited bipolar clustering characteristics, with WY exhibiting low-value clustering in the upstream and high-value clustering in the downstream, while CS showed the clustering characteristics of a scattered distribution of cold and hot spots from 2001 to 2020. The spatial patterns of aggregation locations in CS and HQ were relatively similar, with clusters of higher ES values mainly distributed in the western and central regions and clusters of lower ES values mainly located in the eastern and southeastern regions, while the aggregation of WY was spatially concentrated. Overall, the CS showed a significant positive correlation with HQ, but a significant negative correlation with WY. Spatially, WY and HQ, CS, and SC showed a substantial trade-off relationship in the northwest and southeast parts of the study area, while HQ, CS, and SC mainly exhibited a synergistic relationship in most parts of the study area. Slope and temperature had high influencing factor coefficients on multiple ESs; the mixed effect of terrain and natural factors was significantly greater than the impact of a single factor on ESs, and terrain factors played an essential role in the changes in ESs. The findings can provide technical and theoretical support for integrated scientific ecosystem management and sustainable development at the local scale.

“…These differences were mainly because the estimation of water conservation in our study considered rainfall interception in the rainy season and the regulation of runoff in the dry season. Accordingly, the water balance and canopy interception residual methods that we applied are frequently used to determine the quantity of a certain functional layer or time scale of the forest water conservation function [14,20]. In the rainy season, the water conservation amount for retaining floodwaters in bamboo forests was 469 ± 37 mm, which was higher than that in tea plantations (402 ± 19 mm), indicating that bamboo forests had a higher rainwater interception capacity.…”

“…Moreover, the estimation results of different methods vary greatly and are not comparable [19,21,22]. Meanwhile, the optimization and improvement of water conservation functions based on the above evaluation results are inevitably limited [20,23]. Hence, developing comprehensive evaluation and quantification methods for forest water conservation is an urgent requirement.…”

The rapid expansion of tea plantations (Camellia sinensis), which replace local natural forests, decreases the water conservation function in the headwater region and threatens regional water security. However, studies focusing on the comprehensive evaluation and improvement of the water conservation function of natural forests and tea plantations are lacking. In this study, we developed a comprehensive evaluation method for the water conservation function by investigating, monitoring, and conducting process model simulations of 221 tea plantation and natural forest (bamboo forest) samples obtained in the field. We also quantified the trade-off between water conservation and carbon sequestration. The results showed that the tea plantations had lower annual water conservation than the bamboo forests. Slope was the most critical influential variable affecting water conservation in tea plantations. Strict control should be exercised in the development of steep slopes above 20° for tea plantations, to enhance the regional water conservation capacity. Water conservation in bamboo forests increased to the maximum level at a planting density (SD) of approximately 2500–2700 tree/ha and then decreased quickly. The optimal SD values of bamboo forests were 2500, 2600, and 2650 trees/ha at slopes of 10°, 15°, and 20°, respectively, which can maintain higher water conservation and adequate carbon sequestration. Overall, water conservation and carbon sequestration increased by approximately 22.6% and 13.7%, respectively, compared with the average values for bamboo forests. However, at slopes >20°, a strong trade-off was observed between water conservation and carbon sequestration, and competing ecosystem services accompanied those, which were hard to balance and which resulted here in disproportionate water conservation at the cost of carbon sequestration loss.

“…Furthermore, in areas where grassland degradation is prevalent, including the alpine meadows and grasslands of the Tibetan Plateau, converting cropland and barren land to grassland has been a priority (Dong et al, 2022; Zeng et al, 2022). This conversion helps restore the ecological functions of grasslands, such as providing habitat for livestock and wildlife, boosting local economies, and providing water security (Li, Zhang, et al, 2021; Liu et al, 2022; Wang & Gong, 2022). In addition, the GFGP has influenced the spatial distribution and connectivity of different land cover types.…”

A deeper understanding of the interactions between ecosystem services (ESs) and the drivers of the landscape patterns behind them is critical to how ecological restoration projects in ecologically sensitive and fragile areas are planned and managed. However, few studies have explored the response patterns of ESs to changes in landscape patterns from a geospatial perspective. This study aimed to reveal the relationship between key ESs and landscape pattern responses at spatial scales and to propose the optimization of ecological restoration measures in response to ES trade‐offs problem. The InVEST and CASA models were used to assess the spatial and temporal characteristics of five key ESs in the Beichuan River Basin since the completion of the National Grain to Green Program (2000–2020), selected five key factors are as below: habitat quality (HQ); net primary productivity (NPP); water supply (WS); soil conservation (SC); and water conservation (WC). Geographically weighted regression (GWR) models were used to reveal the trade‐offs and synergies between ESs and the driving mechanisms of landscape patterns from a geospatial perspective. The results showed that landscape connectivity in the study area improved and landscape fragmentation decreased during 2000–2020, accompanied by the increase in HQ, SC, and WC, while NPP and WS decreased. The trade‐offs between ESs appeared mainly between NPP and other ESs, with the NPP–WS pair trade‐off being the strongest. Spearman correlation analysis, geographic detectors, and GWR revealed that the dominant landscape pattern indices affecting ESs showed good agreement. The interaction of the two landscape pattern indices had stronger explanatory power for the variation in ESs than any single landscape pattern index. The patch density index, as the most important landscape pattern index affecting NPP and WS, should be the primary consideration in future landscape planning to reconcile the contradiction between WS and NPP. Because of the inherent spatial heterogeneity of ESs and landscape patterns, analyzing their response relationships from a geospatial perspective can provide scientific guidance to decision‐makers.
