“…Its most important climatic feature is the pronounced seasonal temperatures and precipitation changes [37], with an average annual precipitation of 111 mm~876 mm and an average temperature of − net primary productivity in grasslands but increases water yield and soil conversion [28,29]. Meanwhile, precipitation had a greater positive effect on vegetation carbon sequestration than that of temperature [30]. The response of vegetated ecosystems to climate change is a complex systemic process that exhibits specific values of spatial variation.…”

Exploring the responses of ecosystem services to climate change is an essential prerequisite for understanding the global climate change impact on terrestrial ecosystems and their modeling. This study first evaluated the ecosystem services including net primary productivity (NPP), soil conservation (SC) and water yield (WY), and climate factors including precipitation, temperature, and solar radiation from 2000 to 2020 on the Loess Plateau, and then analyzed their relationships and threshold effects. The results found that precipitation in the region had significantly increased since 2000 while solar radiation decreased; mean annual temperature however did not change significantly. NPP and SC showed an increasing trend while WY showed a decreasing trend. The most significant climate factor affecting ESs was precipitation. With the increase of precipitation, all three types of ecosystem services showed a significant increasing trend, but the facilitating effect for NPP and WY began to be weakened when precipitation reached the thresholds of 490 mm and 600 mm, respectively. This occurred because in regions with already sufficient precipitation to support NPP there is limited capacity for NPP to increase compared to areas of arid grasslands. In these regions, high vegetation cover leads to increased evapotranspiration which reduces the positive influence of increasing precipitation on WY. The results can offer a reference for the level of ecological restoration success.

“…The regional carbon storage in the subtropical China's forest area accounts for about 65% of the national total carbon stock (Li et al, 2003). The impact of regional ecosystem on environment and the response of regional ecosystem to climate change have been hot topics (Li et al, 2015;Yuan et al, 2017;Guo et al, 2020;Ji et al, 2022). However, few studies have specifically addressed the impacts of drought on vegetation productivity in the subtropical China, even though drought occurred frequently and have greatly affected the vegetation productivity (Zhang et al, 2017).…”

Drought is one of the main factors limiting forest productivity, and thus greatly affects the carbon sink capacity of forests. Here we first chose two drought indices including standardized precipitation evapotranspiration index (SPEI) and self-calibrating Palmer drought severity index (scPDSI) to reflect and analyze the spatiotemporal patterns of drought in the subtropical China. Then, the validated CASA (Carnegie-Amer-Stanford Approach) model was applied to estimate forest net primary productivity (NPP) and further quantify the contributions of drought events and their characteristics on forest NPP. The results showed that drought events during 2000–2015 have resulted in a mean decline of forest NPP of 7.2%. Moderate or severe drought events reduced NPP more significantly than extremely severe drought events. In addition, there was 1–2 years of lagging in the NPP responses to drought, and the lagging time varied with forest types. Our study suggests that forest managers and local governments should pay more attention to the places with moderate and severe drought events, and take measures to avoid NPP decline within the 2 years after drought. Our study also provides data support for further identifying the contribution of drought to ecosystem carbon fluxes in the subtropical China.
