The effects of heat stress are spatially heterogeneous owing to local variations in climate response, population density, and social conditions. Using global impact models from the Inter-Sectoral Impact Model Intercomparison Project, our analysis shows that frequency intensity events increase, especially tropical regions (geographic perspective) developing countries (national perspective), even with warming held 1.5 °C target. An additional 0.5 increase 2 target leads >15% land area becoming...

Abstract Drought is the most recurrent and destructive hazard in arid semiarid regions will only become more complex under climate change. It vital to characterize various types of drought, investigate potential factors affecting different assess relationship between drought types. In this study, Standardized Precipitation Index Runoff were used meteorological hydrological respectively, characteristics mechanisms 17 catchments on Loess Plateau from 1961 2013. Furthermore, propagation time...

This study focuses on changing trends in precipitation across mainland China during the period 1957–2014. We explore influence of El Niño–Southern Oscillation (ENSO), Pacific Decadal (PDO), and related large-scale atmospheric circulation variables changes precipitation. The number wet days showed statistically significant downward North China, Jianghuai, South Southwest but upward Tibetan Plateau Northwest China. However, very increased regions there was an increase spatial variability a...

Understanding historical and future drought patterns is crucial to acclimation the mitigation of drought. The negative impact China’s droughts on social economy has attracted attention; however, there still no comprehensive or long-term monitoring pattern for droughts. Here we evaluated precipitation temperature simulation capability Coupled Model Intercomparison Project Phase 6 (CMIP6) temporal spatial during 1961–2099 across China. results show that multi-model ensemble mean (MME) more...

Abstract Baseflow is an all‐important replenishment feature of the hydrologic cycle for maintaining surface water in basins across world. Understanding its dynamics and influence climate variability human activities will be beneficial developing sustainable water‐management strategies. In this study, we selected 11 within Loess Plateau (a typical semiarid region China) assessment variations baseflow index ( BFI ; ratio volume to total streamflow volume) during period 1961–2014. We compared...

This paper intends to clarify that the spatial and temporal evolutionary patterns of regional vegetation their relationship with climate form a premise ecological conservation environmental governance, play an important role in maintaining ecosystem balance promoting sustainable development. Based on measured data collected from NDVI remote sensing products meteorological stations, variation Anhui Province 2001 2019 was determined through trend analysis measurement methods involving...

Abstract Tropical cyclones (TCs) are known to bring heavy rainfall, strong winds and severe storm surges simultaneously, resulting in tremendous damage beyond the effects of a single hazard. However, compound impacts TC multi‐hazards remain unexplored macroeconomic assessments. Here, we provide empirical evidence on multi‐hazard economic losses for first time. We used national panel provincial output China over 2000–2020. Our results show that total impact severest can represent up 14 times...

Abstract The frequency and intensity of drought events are increasing with warming climate, which has resulted in worldwide forest mortality. Previous studies have reached a general consensus on the size-dependency resistance to drought, but further understanding at local scale remains ambiguous conflicting evidence. In this study, we assessed impact canopy height broadleaf deciduous southwestern China for 2010 extreme event using linear regression random (RF) model. Drought condition was...

The thermal comfort of different shaded spaces in parks varies noticeably, and it is also a key factor influencing crowd gathering. Longzi Lake Beach Park Zhengzhou was used as study area this research. For analysis, index for three space types (unshaded, semi-shaded, fully-shaded) aggregation were used. results show that during autumn, visitors are sensitive to the spaces, location playing field differs significantly. Air temperature solar radiation two factors influence tourists’ most....

As an important part and the core link of a terrestrial ecosystem, vegetation is main means for human to regulate climate mitigate increase in atmospheric CO2 concentration. The Yangtze River Delta (YRD) region urban agglomeration with strongest comprehensive strength among developing countries (China). In context global change, rapid, comprehensive, detailed understanding spatio-temporal characteristics variation tendency net ecosystem productivity (NEP) its response during rapid...

Monitoring the lake waterbody area in Qinghai–Tibet Plateau (QTP) is significant dealing with global climate change. The latest released Landsat-9 data, which has higher radiation resolution and can be complemented other Landsat data to improve imaging temporal resolution, have great potential for applications extraction. However, no study published on identifying waterbodies lakes large-scale plateau scenes based data. Therefore, we relied Google Earth Engine (GEE) platform selected ten...

Abstract Geological sequestration of carbon dioxide (CO2) is considered an important technology for mitigating the increasing level atmospheric CO2. One most common methods CO2 geological to inject into depleted oil reservoirs, which recovers part remaining that has been unrecovered by simpler recovery (e.g., water injection). Previous studies have shown such CO2-enhanced (CO2-EOR) effectively serves as a method because successful CO2-EOR typically results from efficient displacement...

The monitoring of lake waterbody area in the Qinghai Tibet Plateau (QTP) is great significance to deal with global climate change. As latest generation Landsat series satellites, Landsat-9 data not only have higher radiometric resolution, but also cooperate other satellites greatly improve temporal resolution. It has application potential monitoring. In order explore performance different algorithms for extracting and under large-scale QTP regions, this study relies on Google Earth Engine...

Greenhouse vegetable production in China not only increases farmers’ income, but also the risk of nitrogen losses due to excessive water and fertilizer input. Nitrogen losses, including potent greenhouse gas nitrous oxide (N2O), are driven by content, soil temperature pH; regulated available organic carbon inorganic (N); affected management. Therefore, a process-based model was applied explain complex interaction factors affecting N form N2O, NH3 NO3− from system northeast suburb Beijing,...

Evaptotranspiration (ETc) is a crucial link in the farmland water cycle process. To accurately obtain citrus ETc different slope positions, METRIC, RSEB, and FAO Penman–Monteith (P-M) models were constructed based on unmanned aerial vehicle (UAV) multispectral images to invert values. The of calculated by P-M model was used as reference standard, accuracy inversion evaluated METRIC RSEB model. results showed that R2, RMSE, SE 0.396 0.486, 4.940 3.010, 4.570 2.090, respectively, indicating...

Optimizing the spatial pattern (spatial compositive and configuration) of urban greenspace can effectively alleviate heat island effect. While relationship between air temperature (AT) composition has been widely studied, this study aimed to investigate AT configuration its diurnal variations scale effects. Based on hourly data from 36 meteorological stations in Changsha, China, land cover interpreted Gaofen 2 remote sensing images, first quantified (i.e., percent greenspace) average patch...

Aims: Dujiangyan is located in a regional hotspot of biodiversity, which has significantly high avian diversity.However, comprehensive list bird species still lacking there.Therefore, we conducted fixed-line transects surveys from May 2016 to August 2019 map the diversity region.Methods: Comprehensive have been done evaluate breeding birds by using fixed line method.A total 10 survey lines were set up inside and outside protected areas Dujiangyan, covering wide range diverse habitats at...
