Drought is part of natural climate variability and ranks the first disaster in world. forecasting plays an important role mitigating impacts on agriculture water resources. In this study, a drought forecast model based random forest method proposed to predict time series monthly standardized precipitation index (SPI). We demonstrate application by four stations Haihe river basin, China. The random‐forest‐ (RF‐) has consistently shown better predictive skills than ARIMA for both long short...
Leptocybe invasa is a globally invasive pest of eucalyptus plantations, and steadily spread throughout China. Predicting the growth area L. in China beneficial to establishment early monitoring, forecasting, prevention this pest. Based on 194 valid data points 21 environmental factors China, study simulated potential distribution under three current future climate scenarios (SSPs1–2.5, SSPs2–3.5, SSPs5–8.5) via MaxEnt model. The used species model (SDM) toolbox ArcGIS software analyze range...
Frequent droughts induced by climate warming have caused increasing impacts on the vegetation of Loess Plateau (LP). However, effects drought are highly dependent when occurs and how long it lasts during growing season. Unfortunately, most existing indices ignore differences in different growth stages. In this study, we first established a phenology-based condition index, namely weighted index (WVCI), which accounts for sensitivity to assigning specific weights phenological stages...
Dissolved organic matter (DOM) is the most active component in soil environment. Understanding chemical diversity of DOM and interaction physicochemical properties are key to managing peatland under succession. In this study, we aimed understand effects succession on DOM. We collected samples (topsoil: 0–10 cm, subsoil: 10–20 cm) from during different stages mid–high latitude northern regions, determined changes quantity quality using fluorescence spectroscopy parallel factor analysis. found...
Abstract It is of great interest to elucidate the biogeographic patterns soil microorganisms and their driving forces, which are fundamental predicting alterations in microbial‐mediated functions arising from environmental changes. Although vertical movement dissolved organic matter (DOM) drives cycle nutrients such as carbon, restored ecosystem, relationship between DOM microbial nutrient utilization remains be determined. Here, we investigated changes community at 0–40 cm depth profile...
The Qinghai-Tibet Plateau is rich in renewable solar energy resources. Under the background of China’s “dual-carbon” strategy, it great significance to develop a global horizontal irradiation (GHI) prediction model suitable for Tibet. In radiation balance budget process Earth-atmosphere system, clouds, aerosols, air molecules, water vapor, ozone, CO2 and other components have direct influence on flux received at surface. For descending shortwave Tibet, attenuation effect clouds key variable...
Loess Plateau (LP), China This study investigated the spatiotemporal dynamics of vegetation drought on LP using an improved temperature index (ITVDI) and explored its time-lag link with teleconnection factors. Findings indicated that: (1) ITVDI is effective tool for monitoring; (2) droughts were primarily characterized by mild to moderate intensity, spring manifesting most expansive drought-stressed areas (about 61.89% pixels); (3) approximately 71.69% region exhibited increasing trend in...

Recently, the Tibetan Plateau (TP) has experienced dramatic climate change, which influence atmospheric and hydrological cycles. The understanding of surface water dynamics is essential to further investigate balance hydrologic cycle in this region. In study, we used all available Landsat Surface Reflectance imagery that generated Modified Normalized Difference Water Index (MNDWI) overlapped TP time-series for 1996–2019. We detected annual changes using LandTrendr algorithm on Google Earth...
Understanding the historical dynamics of animal species is critical for accurate prediction their response to climate changes. During late Quaternary period, Southeast Asia had a larger land area than today due lower sea levels, and its terrestrial landscape was covered by extensive forests savanna. To date, however, distribution fluctuation vegetation impacts on genetic structure demographic history local animals during Last Glacial Maximum (LGM) are still disputed. In addition, responses...
Droughts are widespread in China and have brought considerable losses to the economy society. intricate, stochastic processes with multi-attributes (e.g., duration, severity, intensity, return period). However, most drought assessments tend focus on univariate characteristics, which inadequate describe intrinsic characteristics of droughts due existence correlations between attributes. In this study, we employed standardized precipitation index identify events using China’s monthly gridded...
Tree line ecotone in the Changbai Mountains has undergone large changes past decades. locations show variations on four sides of mountains, especially northern and western sides, which not been fully explained. Previous studies attributed such to temperature. However, this study, we hypothesized that topographic controls were responsible for causing tree Mountains. To test hypothesis, used IKONOS images WorldView-1 image identify developed a logistic regression model using topographical...
Despite decades of investigation, consensus has yet to be reached on when and where wheat replaced millet as the primary crop in core regions early Imperial China. Previous studies have suggested that cultivation likely became widespread prior or during Han Dynasty (202 BC–AD 220). Here, we tested this hypothesis by applying archeobotanical tools plant remains found five pottery model granaries ( cang ) entombed a newly excavated late Western burial at Longzaocun cemetery Guanzhong Basin....
Water shortages have always been the primary bottleneck for healthy and sustainable development of ecological environment on Loess Plateau (LP). Proper water resource management requires knowledge spatiotemporal characteristics precipitation frequency. This paper employed gridded dataset obtained from China Meteorological Data Service Centre to present a spatially explicit characterization frequencies in tandem with their return periods LP based L-moment method. The 60% 80% mean annual 1981...
