The carbon storage of terrestrial ecosystems is closely related to global climate change. Therefore, assessing the impact land-use changes on instructive reduce emissions. Taking an arid region in northwest China as example, this paper analyzed from 1980 2015. It used CA-Markov model predict pattern 2020 2050, and sequestration module Integrated Valuation Ecosystem Services Tradeoffs (Invest) mode assess ecosystem over past 35 years next 30 discusses ecosystems. results showed that: (1)...
Abstract. Ecosystems in arid areas are fragile and easily disturbed by various natural human factors. As tracers widely exist nature, stable isotopes can be valuable for studying environmental change the water cycle. From 2015 to 2020, we took Shiyang River basin, which has highest utilization rate of resources most prominent contradiction use, as a typical demonstration basin establish improve isotope hydrology observation system. The data system classified type (precipitation, river water,...
Abstract. The processes of water storage have not been fully understood in different vegetation zones mountainous areas, which is the main obstacle to further understanding hydrological and improving resource assessments. To understand process soil movement (alpine meadow (AM), coniferous forest (CF), mountain grassland (MG) deciduous (DF)) this study monitored temporal spatial dynamics hydrogen- oxygen-stable isotopes precipitation Xiying River basin. results show that order evaporation...
Abstract. In water-scarce arid areas, the water cycle is affected by urban development and natural river changes, urbanization has a profound impact on hydrological system of basin. Through an ecohydrological observation established in Shiyang River basin inland zone, we studied using isotope methods. The results showed that significantly changed process accelerated rainfall-runoff due to increase land area, mean residence time (MRT) fluctuating downward trend from upstream downstream was...
Abstract. Stable isotopes in precipitation can effectively reveal the process of atmospheric water circulation, serving as an effective tool for hydrological and resource research, climate change, ecosystem studies. The scarcity stable isotope data has hindered comprehension regional hydrology, climate, ecology due to discontinuities on a temporal scale unevenness spatial scale. To this end, we collated hydrogen oxygen from 842 stations Eurasia 1961 2022, totalling 51 752 records. across...
Abstract. In recent years, China's terrestrial ecosystems have experienced frequent droughts. How these droughts affected carbon sequestration by the is still unclear. this study, process-based Boreal Ecosystem Productivity Simulator (BEPS) model, driven remotely sensed vegetation parameters, was employed to assess effects of on net ecosystem productivity (NEP) in China from 2000 2011. Droughts differing severity, as indicated a standard precipitation index (SPI), hit extensively 2001, 2006,...
As an important means to cope with global climate change, ecological restoration projects have a huge impact on ecosystem carbon storage functions. Scientifically evaluating the response process and mechanism of basin functions in is beneficial improvement regional ecosystems. Taking Shiyang River Basin (SRB) as example, based perspective "carbon sink–carbon source" mutual transformation, current study utilized InVEST (Integrated Valuation Ecosystem Services Tradeoffs) model analyze...
In arid oasis regions, water resources are severely scarce, with agricultural usage far exceeding that of more humid areas. As a result, assessing non-productive losses in farmland becomes crucial for estimating the requirements reliant on irrigation cultivation. From April 2018 to October 2021, we established an observation system Minqin Oasis farmland. By utilizing hydrogen and oxygen isotopes precipitation, soil water, maize stem xylem quantified loss (FE) infiltration rate (fe) fields....
Abstract Glaciers are of crucial importance for the livelihood local populations, which depend on their meltwater water and energy supplies. For this reason, seasonal variations oxygen‐18 glacial stream sources within a small catchment in south western China were investigated during wet season. The results showed significant difference existed among meltwater, rainwater, ground water, significantly variation precipitation occurred observed period. streamflow Baishui was separated into...
Abstract Studying the spatial distribution pattern of soil organic carbon and its influencing factors is essential for understanding cycle in terrestrial ecosystems. Soil samples from four active layers typical vegetation types (Populus, subalpine shrubs, Picea crassifolia Kom, alpine meadow) upper reaches Shiyang River basin Qilian Mountains were collected to determine content physicochemical properties. The results show following: (1) There are significant differences vertical watershed,...
As one of the most destructive and costly natural disasters, drought has far-reaching negative effects on agriculture, water resources, environment, human life. Scientific understanding propagation from meteorological to hydrological is great significance for accurate forecasting preventing mitigating disasters. The objective this study analyze spatio-temporal variational characteristics associated driving mechanisms in eastern Qilian Mountains using standard precipitation index (SPI),...
The mass-particle size distributions (MSDs) of 9 elements in ground-based aerosol samples from dust storm (DS) and non-dust (N-DS) periods were determined for 12 sites major desert regions northern China. masses the (Al, Fe, K, Mg, Mn, Sc, Si, Sr Ti) atmosphere dominated by local mineral that averaged 270 mg m−3, MSDs approximately log-normal. On basis Al data, < 10 mm particles account ˜84% total mass over deserts. Model-calculated (''100-step'' method) dry deposition velocities (Vd)...
Yangpota Mountain in Zhuanglang County, Loess Plateau Hilly Area. In dry and degraded ecosystems, water scarcity remains the most significant restriction to vegetation restoration ecosystem rehabilitation. Plants cannot directly absorb groundwater Plateau, so soil moisture is very important for growth of plants. Through observation system terraces, we explore influence mechanism terrace construction on moisture. The results show that terraces higher than slope farmland natural surfaces. 0-1...
Abstract Accurately quantifying the evaporation loss of surface water is essential for regional resources management, especially in arid and semi‐arid areas where are already scarce. The long‐term monitoring stable isotopes (δ 18 O δ 2 H) can provide a sensitive indicator by evaporation. In this study, we obtained samples Shiyang River Basin from April to October between 2017 2019. spatial temporal characteristics show trend enrichment summer, depletion spring, deserts mountains. Local...
