    Himalayas as a global hot spot of springtime stratospheric intrusions:Insight from isotopic signatures in sulfate aerosols

    查看更多>>摘要：Downward transport of stratospheric air into the troposphere(identified as stratospheric intrusions)could potentially modify the radiation budget and chemical of the Earth's surface atmosphere.As the highest and largest plateau on earth,the Tibetan Plateau including the Himalayas couples to global climate,and has attracted widespread attention due to rapid warming and cryospheric shrinking.Previous studies recognized strong stratospheric intrusions in the Himalayas but are poorly understood due to limited direct evidences and the complexity of the meteorological dynamics of the third pole.Cosmogenic 35S is a radioactive isotope predomi-nately produced in the lower stratosphere and has been demonstrated as a sensitive chemical tracer to detect stratospherically sourced air mass in the planetary boundary layer.Here,we report 6-month(April-September 2018)observation of 35S in atmospheric sulfate aerosols(35SO42-)collected from a remote site in the Himalayas to reveal the stratospheric intrusion phenomenon as well as its potential impacts in this region.Throughout the sampling campaign,the 35SO42-concentrations show an average of 1,070±980 atoms/m3.In springtime,the average is 1,620±730 atoms/m3,significantly higher than the global existing data measured so far.The sig-nificant enrichments of 35SO42-measured in this study verified the hypothesis that the Himalayas is a global hot spot of stratospheric intrusions,especially during the springtime as a consequence of its unique geology and atmospheric couplings.In combined with the ancillary evidences,e.g.,oxygen-17 anomaly in sulfate and modeling results,we found that the stratospheric intrusions have a profound impact on the surface ozone concentrations over the study region,and potentially have the ability to constrain how the mechanisms of sulfate oxidation are affected by a change in plateau atmospheric properties and conditions.This study provides new observational constraints on stratospheric intrusions in the Himalayas,which would further provide additional information for a deeper understanding on the environment and climatic changes over the Tibetan Plateau.

    A novel diurnal and seasonal variation analysis of BTEX in Bengaluru urban area

    查看更多>>摘要：In the urban atmosphere of Bengaluru,various volatile organic compounds(VOCs),particularly Benzene,Toluene,Ethylbenzene,and Xylene(BTEX),have shown an increasing trend in concentration.The present research was conducted during summer and monsoon seasons,focusing on Kadubeesanahalli,a high-traffic area within the Bengaluru Metropolitan City.Hourly sample data was collected using a BTEX analyzer(Model GC955-600)and subsequently transformed into daily,monthly,and seasonal values.The study revealed distinct patterns in benzene concentrations.Benzene levels were lowest during the early morning hours,specifically from 1:00 a.m.to 7:00 a.m..Concentrations then increased from 7:00 a.m.to 9:00 a.m.and again from 4:00 p.m.to 11:00 p.m.,corresponding to the morning and evening peak traffic hours.However,between 10:00 a.m.and 4:00 p.m.,the concentration decreased due to reduced traffic levels.These diurnal variations in benzene concentration are influenced by meteorological parameters.Comparing the two seasons,higher concentrations of Benzene,Ethyl-Benzene,and MP-xylene were observed during the summer season.This increase is attributed to the elevated temperatures during summer,which promote the vaporization of BTEX compounds.Conversely,lower BTEX concentrations were recorded during the monsoon season due to the wet deposition process.The observed positive correlation(r＞0.5)among BTEX parameters strongly suggests a common source,most likely originating from vehicular emissions.

    Biological soil crusts and their potential applications in the sand land over Qinghai-Tibet Plateau

    查看更多>>摘要：The Qinghai-Tibet Plateau is now experiencing ecological degradation risks as a result of climate change and human activities.The alpine grassland ecology in permafrost zones is fragile and susceptible to deterioration due to its high altitude,low temperature,and limited oxygen,which complicates the repair of damaged land.Bio-logical soil crusts(BSCs)are crucial for land restoration in plateau regions because they can thrive in harsh conditions and have environmentally beneficial traits.Inoculated biological soil crust(IBSC)has shown success in low-altitude desert regions,but may not be easily duplicated to the plateau environment.Therefore,it is essential to do a comprehensive and multifaceted analysis of the basic theoretical comprehension and practical application of BSCs on the Tibetan Plateau.This review article aims to provide a brief summary of the ecological significance and the mechanisms related to the creation,growth,and progression of BSCs.It discusses the techniques used for cultivating BSCs in laboratories and using them in the field,focusing on the Qinghai-Tibet Plateau circumstance.We thoroughly discussed the potential and the required paths for further studies.This study may be used as a basis for selecting suitable microbial strains and accompanying supplemental actions for implementing IBSCs in the Qinghai-Tibet Plateau.

    Impacts of multi-scenario land use change on ecosystem services and ecological security pattern:A case study of the Yellow River Delta

    查看更多>>摘要：The Yellow River Delta(YRD),a critical economic zone along China's eastern coast,also functions as a vital ecological reserve in the lower Yellow River.Amidst rapid industrialization and urbanization,the region has witnessed significant land use/cover changes(LUCC),impacting ecosystem services(ES)and ecological security patterns(ESP).Investigating LUCCs effects on ES and ESP in the YRD is crucial for ecological security and sus-tainable development.This study utilized the PLUS model to simulate 2030 land use scenarios,including natural development(NDS),economic development(EDS),and ecological protection scenarios(EPS).Subsequently,the In VEST model and circuit theory were applied to assess ES and ESP under varying LUCC scenarios from 2010 to 2030.Findings indicate:(1)Notable LUCC from 2010 to 2030,marked by decreasing cropland and increasing construction land and water bodies.(2)From 2010 to 2020,improvements were observed in carbon storage,water yield,soil retention,and habitat quality,whereas 2020-2030 saw increases in water yield and soil retention but declines in habitat quality and carbon storage.Among the scenarios,EPS showed superior performance in all four ES.(3)Between 2010 and 2030,ecological sources,corridors,and pinchpoints expanded,displaying sig-nificant spatial heterogeneity.The EPS scenario yielded the most substantial increases in ecological sources,corridors,and pinchpoints,totaling 582.89 km2,645.03 km2,and 64.43 km2,respectively.This study highlights the importance of EPS,offering insightful scientific guidance for the YRD's sustainable development.
