As an important natural resource, forest land plays a key role in the maintenance of ecological security. However, variations of forest land in the agropastoral ecotone of northern China (AENC) have attracted little attention. Taking the AENC as an example and based on remote-sensing images from 200…
Frequent droughts inflict serious damage upon the economy and agricultural production of Gansu Province; therefore, establishing accurate and reliable agricultural drought monitoring models through advanced methodologies is of paramount importance for drought prevention and mitigation efforts in the…
Rural drinking water safety projects constitute a critical livelihood initiative for achieving comprehensive moderate prosperity. This study, based on statistical data, field investigations, and survey questionnaires, employs the entropy weight method and fuzzy mathematics approach to evaluate the c…
The land use patterns in mining areas of semi-arid regions are undergoing tremendous changes under mining disturbances. Taking the Datong mining area in Shanxi Province, one of the eight major coal production bases in China, as the research object, this study analyzes the spatiotemporal changes of l…
To address the forestry technical challenges of Ammopiptanthus mongolicus, characterized by long taproots, few fibrous roots, difficult seedling rooting, and low transplant survival rates, this study investigated different root pruning intensities combined with varying concentrations of hormone (IBA…
Desert annual plants exhibit rapid growth rates and strong reproductive capacity, possessing significant forage, medicinal, and ecological value. Through literature review, verification of specimen collection records, and field surveys, this study clarifies the species richness, distribution pattern…
Plastic mulching is an effective approach for improving crop yields in arid region farmlands and is widely applied in agricultural production. Investigating the response of soil greenhouse gas emissions to mulching under different cropping systems is of great significance for greenhouse gas mitigati…
Moisture is the primary controlling factor of the nitrogen mineralization process in wetland soils and plays an important role in nitrogen cycling processes in wetland soils. Taking the Gannan Gahai Wetland as the study area, four degradation levels (Undegraded UD, Lightly Degraded LD, Moderately De…
The Hotan region is located in the southwestern part of Xinjiang, characterized by an arid climate and scarce precipitation. Groundwater serves as an important drinking water source in the Hotan region, making the investigation of fluoride distribution and genesis in groundwater of great significanc…
Employing a combination of the water balance method, field investigation, and remote sensing imagery data, this study expounds upon the evolution of riverbed permeability performance and the water environment response characteristics under varying river channel water delivery methods following ecolo…
Changes in unfrozen water content directly influence the thermodynamic and deformation characteristics of frozen soil, and constitute a critical condition for hydro-thermal numerical computations. To investigate the variation law of unfrozen water content, the particle size distribution of soil is f…
Vadose zone soil water infiltration plays a crucial role in the hydrological cycle. An in-depth understanding of the interrelationships among rainfall, ponding, and infiltration processes is of great significance for assessing soil water replenishment and precipitation redistribution in desert envir…
Climate change has significantly impacted the water cycle in the high mountain regions of Central Asia, exacerbating regional water supply-demand conflicts. Understanding the characteristics of runoff components in inland rivers is crucial for water resource management. Based on meteorological and r…
Based on daily precipitation data from 13 meteorological stations in the Guanzhong Plain from 1957 to 2019, various extreme precipitation indices were calculated using methods such as simple linear regression, Pearson correlation analysis, and wavelet coherence analysis, and their spatiotemporal var…
In data-scarce regions, the lack of observational data for precipitation, temperature, and other variables affects the accuracy of flood forecasting, thereby impacting flood control, drought resistance, water resources planning, and related efforts. Therefore, conducting applicability analysis of ex…
Using daily meteorological data from 99 meteorological stations in Xinjiang from 1961–2020, the daily Meteorological Drought Composite Index (MCI) sequences for each station were calculated according to the latest revised national standard "Grades of Meteorological Drought". The spatiotemporal varia…
Utilizing 24-hour precipitation forecasts at 36-hour lead time from the ECMWF (European Center for Medium-Range Weather Forecast) and GRAPES-GFS (China Meteorological Administration's GRAPES Global Numerical Prediction Operational System, Global/Regional Assimilation and Prediction System-Global For…
Using parallel observation and comparative observation data of precipitation phenomena from 2363 meteorological stations nationwide during 2017-08 to 2018-08, a comparative analysis was conducted on automatic observation data of five precipitation phenomena—rain, snow, drizzle, hail, and sleet—from …
To investigate the applicability of ERA5 reanalysis precipitation data over China, using daily precipitation data from 728 stations nationwide as reference, we analyzed the accuracy of ERA5 reanalysis precipitation data across different temporal scales (monthly, seasonal), different climate zones, a…
Based on daily precipitation data from nine meteorological stations in the desert steppe of Inner Mongolia and reanalysis data from the National Centers for Environmental Prediction (NCEP)/National Center for Atmospheric Research (NCAR), this study employs statistical methods to analyze the characte…
Based on MODIS imagery, the China Lake Dataset, and meteorological data, we comprehensively analyzed the variations in lake ice phenology characteristics and influencing factors of Sayram Lake from 2000 to 2019. The results show that: (1) The average dates of lake ice onset and onset of ice melt in …
Based on Landsat series imagery, Digital Elevation Model (DEM), and other datasets, glacier boundary information in the Pengqu River basin from 1990 to 2020 was extracted using remote sensing image processing and visual interpretation methods to investigate the distribution and variation of glacier …
The Tarim River is the longest inland river in China and is considered as an important river to protect the oasis economy and environment of the Tarim Basin. However, excessive exploitation and over-utilization of natural resources, particularly water resources, have triggered a series of ecological…
The farming-pastoral ecotone of northern China (FPENC) provides an important ecological barrier which restrains the invasion of desert into Northwest China. Studying drought and flood characteristics in the FPENC can provide scientific support and practical basis for the protection of the FPENC. Bas…
