“…We set urban, cropland, and crop/natural vegetation mosaics as threat factors and the decay laws of these threat factors are linear. Relevant parameters referred to the Tibetan Plateau research of Hou et al ( 2020 ) and were slightly adjusted according to the classification system of MCD12Q1 (see Table S1 for details). For instance, according to the classification system of MCD12Q1, there are some mixed land cover types, such as crop/natural vegetation mosaics and mixed forests.…”

“…Considering that climate fluctuations take a long period to be stabilized, the study with short-term periods may limit their value. Besides, most of the studies had a coarse scale (e.g., basin or larger), and only a few had a finer resolution (e.g., pixel scale) (Hao et al 2017a , b ; Hou et al 2020 ; Shen et al 2020 ). Coarse-scale studies overlook important information that may be essential for management.…”

Context Climate change has imposed tremendous impacts on ecosystem services. Recent attempts to quantify such impacts mainly focused on a basin or larger scale, or used limited time periods that largely ignore observations of long-term trends at a fine resolution, thereby affecting the recognition of climate change’s effect on ecosystem services. Objectives This study conducts a detailed and spatially explicit recognition of climate change’s effect on ecosystem services and provides an intuitive map for decision-making and climate change adaptation planning. Methods We used long-term time series of ecosystem service assessments and various future climate scenarios to quantify the sensitivity and future exposure of ecosystem services to climate change on the Tibetan Plateau. Results Carbon sequestration (CS) and habitat quality experience significant growth, while water retention did not show any trend. Sensitivity patterns of these ecosystem services vary largely. For CS, more than half of the pixels showed a positive sensitivity to climate change, even though the degree of sensitivity is not high. There is substantial spatial heterogeneity in the exposure of ecosystem services to future climate changes, and high levels of future climate change increase the intensity of exposure. Conclusions This study illustrates the complex spatial association between ecosystem services and climatic drivers, and these findings can help optimize local response strategies in the context of global warming. For example, the existing protected areas have notable conservation gaps for disturbance of future climate change on ecosystem services, especially in the southeastern part of the study area.

“…In constructing the LUESP, this study, through combing the existing research, thinks that the future research should focus on the coordination between different land‐use functions and integrate the multifunctional trade‐off concept into the regulation of land‐use ecological security. The research shows that there are complex trade‐offs and synergies between land‐use functions (Hou et al, 2021), and the multifunctional trade‐off/synergy analysis of land use can identify the multifunctional mechanism, select and optimize the functions types of land use, and further become an important basis for land‐use regulation decision‐making (Ma, 2020).…”

Ecological land is constantly modified by agriculture and construction, which leads to soil erosion, land degradation, soil pollution flood disasters, and many other land ecological security problems, threatening sustainable development. Few studies have been made to construct a land‐use ecological security pattern (LUESP) aimed at achieving urban expansion, food security, and ecological security from the perspective of land‐use needs. This study seeks to provide decision makers with the choice of multi‐scenario LUESPs by simulating the LUESP under different scenarios, offering a reasonable land‐use ecological security regulation strategy. In this paper, the ecological security evaluation method was used to identify key ecological space of a study area and the scenario analysis method was used to set up three security scenarios: ideal security (IS) scenario, satisfactory security (SS) scenario, and bottom‐line security (BS) scenario, thereby constructing the constrained cellular automata (CA) model of the LUESP and simulating the LUESPs under three security scenarios for Xingguo County, China. The results showed that the LUESP construction land index and arable land index did not exceed the total amount of the General Plan of Land Use in Xingguo County under the three security scenarios. Moreover, both key ecological space loss and landscape fragmentation degree were greatly reduced, the ecological patches tend to cluster, and the anti‐jamming ability of the landscape pattern was enhanced. The ranking of LUESPs under three security scenarios was as follows: BS scenario > SS scenario > IS scenario. These results implied that the LUESPs met the demand for land in Xingguo County for ecological security, food security, and economic development, while space occupied is different under three security scenarios. The decision makers can adopt appropriate land‐use ecological security regulation strategies according to the future development plans of the region.

“…The Qinghai-Tibet Plateau is an important geographical region with unique but fragile ecosystems in which key landscape services should be assessed quantitatively for regional sustainability. Hence, Hou et al (2021) explored the relationships of multiple landscape services within this particular region in order to identify the associated key influencing factors considering specific landscape gradients. Subsequently, according to the trade-offs and synergies of landscape services, sustainable management guidelines were further proposed in a climate change and national policy context.…”
