Abstract Changes in the intensity of East Asian summer monsoon (EASM) are critical for regulating regional hydrology, ecology, and human civilization, especially vicinity limit (SML). However, detailed spatial variations SML mainland China over past 2000 years uncertain due to lack high-resolution paleoclimate archives. As a result, accurate location during transition from Medieval Warm Period (MWP) Little Ice Age (LIA), as well its impacts on ecology society, poorly understood. Here, we...
Effective management of municipal solid waste (MSW) is essential for the conservation ecosystems in Qinghai-Tibetan Plateau (QTP). Considering landfill major method MSW management, factors influencing groundwater contamination near sites QTP were studied, based on field investigations, environmental impact assessment, and meteorological hydrogeological analyses. Results indicated that was contaminated heavily by nitrate (PI = 7.5), particularly without an anti-seepage system, followed...
Global warming is a significant challenge, and carbon stocks in terrestrial ecosystems are crucial for reducing the greenhouse effect increasing sinks. A study was conducted Zhengzhou City from 2000 to 2020 using Landsat image spectral reflectance analyze changes stock. Environmental variables such as surface moisture, salinity, vegetation index, brightness, soil texture were constructed. Multiple linear regression (MLR), support vector machine (SVR), random forest (RFR), long short-term...
The westerly jet (WJ) in the upper troposphere, an important atmospheric circulation system, is critical for influencing global climate by changes of its north-south migration and intensity. However, variations during Holocene across Eurasian North America are not well evaluated, which restricts our understanding change those regions. Using general model experiments, here we simulate WJ over past 10ka to show intensity position responding astronomical insolation. Our results suggest that...
Vegetation indexes have been widely used to qualitatively and quantitatively evaluate vegetation cover its growth vigor. To further extend the study of indexes, this paper proposes spatial temporal distribution characteristics specific driving mechanisms based on example Yunnan Province, China, also adds prediction methods indexes. This data region’s normalized index (NDVI), three meteorological factors, eight social factors from 1998 2019. The dynamic change in mechanism NDVI were studied...
Abstract Biomass burning (BB) fractions estimated with the aethalometer model differ from 0 even for pure aerosols fossil fuel (FF) combustion. We used black carbon (BC) partially‐coated non‐absorbing materials to represent typical FF aerosols, and BB were determined model. Thus, are that incorrectly attributed aerosols. The BC morphology mixing state have significant effects on estimation of fractions. For freshly emitted BC, do not deviate significantly 0, fraction is generally in range...
As an important ecological security barrier in China, the environment of Tibet has aroused widespread concern domestically and overseas. Landfills are a major solid waste treatment approach but also cause severe environmental pollution. To date, there no studies related to pollution risk landfills Tibetan areas. This study investigated levels, risk, health possible sources eight heavy metals soils around landfill site Lhasa, Tibet. The results indicated that concentrations soil were...
The Tibet Autonomous Region (TAR) is located in the mid-latitude and high-cold regions, ecological environment most areas fragile. Studying its surface vegetation coverage can identify ecosystem’s development trends provide a specific contribution to global environmental change. normalized difference index (NDVI) better reflect of vegetation. Therefore, based on remote sensing data with resolution 1 km2, air temperature, precipitation, other same period study area from 1998 2019, this paper...
Abstract The East Asian winter monsoon (EAWM) is a crucial climate system in Asia, with significant social and economic impacts. Orbital‐scale variability of the EAWM during Holocene its associated mechanisms, however, are still not fully understood. Based on high‐resolution transient simulation by coupled model, we present here continuous evolution response to orbital forcing. Our simulated springtime variations, consistent grain size records loess, exhibit an obvious strengthening trend...
The atmosphere over the ocean is an important research field that involves multiple aspects such as climate change, atmospheric pollution, weather forecasting, and marine ecosystems. It of great significance for global sustainable development. Satellites provide a wide range measurements aerosol optical properties are very to study characteristics ocean. In this study, depth (AOD) data from seventeen AERONET (Aerosol Robotic Network) stations were used benchmark comprehensively evaluate...
Abstract. Methods based on the absorption Ångström exponent (AAE) are widely used to estimate by brown carbon (BrC), and estimated BrC can be significantly different from 0, even for pure black (BC). However, few studies have systematically quantified effects of BC microphysical properties. Moreover, conditions under which AAE-based methods applicable still unclear. In this work, we models partially coated with non-absorbing materials calculate total absorption. Since is entirely due BC,...
Fine particulate matter (PM2.5) pollution’s passive effects on public health have attracted a great deal of attention. Extensive studies tried to uncover the impacts external drivers PM2.5 pollution variation; however, topography’s remain poorly understood. Using annual high-resolution concentration estimates for PM2.5, this paper quantitatively disentangled geographical topography in China and quantified mountain blocking dispersion macro scale. The results show that, China, plains...
Regional land-use change is the leading cause of ecosystem carbon stock change; it essential to investigate response LUCC achieve strategic goal “double carbon” in a region. This paper proposes residual network algorithm, Residual Multi-module Fusion Network (R-MFNet), address problems blurred feature boundary information, low classification accuracy, and high noise, which are often encountered traditional methods. The algorithm uses an R-ASPP module expand receptive field map extract...
In the process of agricultural development in arid and semi-arid areas, carbon fixation capacity vegetation can be affected to different degrees, but research on its driving factors is lacking. Consequently, this paper focuses Weiku Oasis Xinjiang as area, which estimated with chemical equation a photochemical reaction, using methods such linear system models Geodetector analyze relationship between cropland expansion characteristics from 1990 2020. The influence land-use changes space...
