“…Previous studies have shown that climate warming has greatly increased the evaporation in TP. Therefore, the increase of air temperature can promote vegetation growth, on the other hand, it may also suppress the growth of some vegetation, and human disturbance such as overgrazing will lead to grassland degradation [26,27]. Therefore, areas with increasing trend and significantly increasing trend of NDVI in meadows and grasslands are reducing, which is opposite to the overall variation trend.…”

The fragile alpine vegetation in the Tibetan Plateau (TP) is very sensitive to environmental changes, making TP one of the hotspots for studying the response of vegetation to climate change. Existing studies lack detailed description of the response of vegetation to different climatic factors using the method of multiple nested time series analysis and the method of grey correlation analysis. In this paper, based on the Normalized Difference Vegetation Index (NDVI) of TP in the growing season calculated from the MOD09A1 data product of Moderate-resolution Imaging Spectroradiometer (MODIS), the method of multiple nested time series analysis is adopted to study the variation trends of NDVI in recent 17 years, and the lag time of NDVI to climate change is analyzed using the method of Grey Relational Analysis (GRA). Finally, the characteristics of temporal and spatial differences of NDVI to different climate factors are summarized. The results indicate that: (1) the spatial distribution of NDVI values in the growing season shows a trend of decreasing from east to west, and from north to south, with a change rate of −0.13/10° E and −0.30/10° N, respectively. (2) From 2001 to 2017, the NDVI in the TP shows a slight trend of increase, with a growth rate of 0.01/10a. (3) The lag time of NDVI to air temperature is not obvious, while the NDVI response lags behind cumulative precipitation by zero to one month, relative humidity by two months, and sunshine duration by three months. (4) The effects of different climatic factors on NDVI are significantly different with the increase of the study period.

“…Many researchers believe that the effects of hydrothermal conditions on the vegetation growth in TP are mutual. Studying the response of NDVI and climatic factors in the vegetation growing season in TP should include the study of hydrothermal factors [25,26,27].…”

“…In theory, caterpillar fungus should be able to shift its range upward in response to changing climate ( 41 , 42 ), but it is unknown whether all of the necessary elements of the ecosystem—including edaphic conditions, vegetation, caterpillar species, and the fungus itself—will respond in the same ways and at the same pace to climate change, nor how these climate responses may interact with habitat degradation or other factors ( 60 , 61 ). Evidence that vegetation on the Tibetan Plateau did not shift upward in response to climate warming from 2000 to 2014 ( 62 ) suggests that a lag in creation of a new suitable habitat may prohibit caterpillar fungus from simply “moving up the mountain” as climatic conditions change.…”

SignificanceGlobal demand for species used in traditional medicine is increasing among wealthy urban consumers. This growing trade provides livelihood opportunities for harvesters, but also risks causing resource overexploitation. A dearth of reliable data hinders assessments of whether these species are declining, and why. We investigate these issues for Himalayan caterpillar fungus—one of the world’s most expensive medicinal species—by integrating local harvesters’ knowledge of production trends with ecological modeling. We find that harvesters increasingly attribute declining production to overexploitation, while models indicate that climate warming is also contributing to this decline. Our results underscore the “double whammy” threatening highly valuable species, and demonstrate the complementarity of different knowledge systems for assessing the sustainability of the medicinal resource trade.

“…The seasonal distribution of precipitation is uneven, with most precipitation concentrated in the period June to September. There is a decreasing trend in precipitation from the southeast to the northwest of the plateau 50 . Known as the "Roof of the World" and "Third Pole", the QTP is also an area that is sensitive to global climate change, showing increasing warming and humidification in recent decades 51 .…”

The Qinghai-Tibet Plateau (QTP) supplies many ecosystem services (ESs) that maintain local and global pan-Asian populations and ecosystems. The effects of climate change on ES provision in the QTP will have far-reaching impacts on the region and the many downstream ecosystems and countries that depend on ESs from the "Third Pole". This study undertook a systematic assessment of ES provision, trade-offs and synergies between four ESs (raw material provision, water yield, soil retention, and carbon storage) under future climate scenarios (representative concentration pathway). The results show that: (1) the total amount of the four ESs on the QTP is predicted to increase from 1980 to 2100 for three climate change scenarios. (2) The spatial pattern of ESs on the QTP will not change significantly in the future, and the grassland and forest ESs in the central and southern regions are predicted to increase significantly. (3) The synergistic interactions among ESs were generally consistent at three spatial scales (10 km (pixel), county and watershed scales), but with more significant synergistic effects at the watershed scale. This demonstrates the necessity for the examination of scale-dependent ES dynamics and interactions. This study will supply a reference for further research on long-term ES assessments, especially the dynamic ES changes and the spatial scale dependency of the ES interactions, and provide evidence-based strategies for formulating ecosystem management on the QTP under climate change.
