    Biological crust in sand and dust storm source areas of Asia and its impact on dust emission

    Revealing climatic impacts on the temporal and spatial variation in vegetation activity across China:Sensitivity and contribution

    查看更多>>摘要：Relative weakness in sensitivity and contribution integration,especially lack of specific indicators at spatial and temporal scales,may hinder the formation of systematic knowledge for climate change impact on vegetation activity.Considering the interannual variability and periods difference,we investigated the ecosystem sensitivity to hydrothermal conditions and the contribution of individual climatic factors to vegetation activity on spatiotemporal scales during the period of 1980s-2013 in China.We ran simulations of the Common Land Model (CoLM) to obtain the photosynthetic rate,and used the satellite-derived Normalized Difference Vegetation Index (NDVI),to which we applied a temporal sensitivity analysis,the slope change ratio of accumulative quantity (SCRAQ),and geographical detectors.We show that the discrepancy be-tween warming and precipitation variation contributed to vegetation activity was more notable than the ecosystem sensitivity to hydrothermal conditions,regardless of which temporal and spatial scale was considered.The sensitivity of vegetation activity to hydrothermal variation in most parts of northeastern and western China was higher than elsewhere,and the contribution of warming to vegetation dynamics was relatively high in the Inner Mongolian Plateau and Tibetan Plateau (＞60％),where the contribution of warming to the vegetation distribution was also greater than elsewhere in China.Conversely,the contribution of precipitation variation to vegetation dynamics was comparatively greater in northwestern China and subtropical and tropical regions (＞55 ％).The spatiotemporal contribution of precipitation variation to vegetation activity differed between regions,especially on the Tibetan Plateau and in subtropical and tropical regions.Moreover,both the temporal and spatial sensitivities to climate change were weak in the subtropical and tropical regions,where the contribution of climatic factors to vegetation dis-tribution was also small.Overall,temperature sensitivity and its contribution to vegetation activity were positively associated in most regions.However,the regions where precipitation contributed substantially to vegetation activity were not necessarily also highly sensitive to changes in precipitation within the range of variation explored.

    Climate change and its association with the expansion of vectors and vector-borne diseases in the Hindu Kush Himalayan region:A systematic synthesis of the literature

    查看更多>>摘要：Observed weather and projected climate change suggest an increase in the transmission of vector-borne diseases (VBDs) in the Hindu Kush Himalayan(HKH) region.In this study,we systematically explore the literature for empiric associations between the climate variables and specific VBDs and their vectors in the HKH region.We conducted a systematic synthesis of the published literature on climate variables,VBDs and vectors in the HKH region until the 8th of December 2020.The majority of studies show significant positive associations of VBDs with climatic factors,such as temperature,precipitation,relative humidity,etc.This systematic review allowed us to identify the most significant variables to be considered for evidence-based trend estimates of the effects of climate change on VBDs and their vectors in the HKH region.This evidence-based trend was set into the context of climate change as well as the observed expansion of VBDs and disease vectors in the HKH region.The geographic range of VBDs expanded into previously considered non-endemic areas of highlands (mountains) in the HKH region.Based on scarce,but clear evidence of a positive relationship of most climate variables and VBDs and the observed climatic changes,we strongly recommend an expansion of vector control and surveillance programmes in areas of the HKH region that were previously considered to be non-endemic.

    Cryospheric water regime by its functions and services in China

    430-443页
    查看更多>>摘要：The terrestrial cryosphere functions to provide critical freshwater and serve societies and ecosystems,driving nature's contributions to people(NCP).This becomes increasingly important for the oasis areas in Northwest China.The cryospheric meltwater is in demand to support the economy and reduce poverty,accompanied by growing requirements to protect the environment.We intend to investigate the contributions of cryospheric meltwater by analyzing the spatial functions and services pertinent to provisioning meltwater in China.Based on the currently available datasets during the 2000s of glaciers,snow cover,and permafrost,spatial clustering was utilized to analyze the contributions at the third-level basin scale.Further assessment is carried out for the exposure of primary,secondary,and tertiary industrial sectors to cryospheric meltwater,which reflects the spatiality of potential services that cryospheric meltwater may provide.In results,we spatially cluster the contribution of cryospheric meltwater into six function zones and twenty-seven sub-zones,in association with the degree of their reliance on glaciers,snow cover,and permafrost.Considering the sector's exposure,we further spatially cluster the contribution areas into eleven service zones concerning the potential service of cryospheric meltwater.Generally,the cryosphere contributes approximately 8.3％ of the total water resource in China,with function zones mainly distributed in northeastern China,Qinghai-Tibet Plateau (QTP),and other arid regions of Northwest China with various significance.The overall contribution ratios of the glacier,snow cover,and permafrost to cryospheric meltwater are about 35.6％,56.5％,and 7.9％,respectively.By looking into the service zones,the cryospheric meltwater mainly contributes to the primary industry in Northwest China and QTP,even though it has less significant effects on all other industrial sectors,while the services to the ecosystem are mainly located in QTP and high mountain regions.The results offer an overarching view on the contributions of cryospheric meltwater in China.
