Abstract The Yellow River Delta occupies an important position in the global ecosystem because of its valuable wetland habitat resources for migratory birds on Eastern Pacific migration route. However, it has suffered from severe land degradation soil salinization. This paper assesses distribution maps saline soils during past two decades, using field observations at three points time remote sensing images same periods, combination with spatial models. Soil salinization appears to have...
Improper use of land resources may result in severe soil salinization. Timely monitoring and early warning salinity is urgent need for sustainable development. This paper addresses the possibility potential Advanced Land Imager (ALI) mapping salinity. In situ field spectra data were collected Yellow River Delta, China. Statistical analysis demonstrated importance ALI blue near infrared (NIR) bands A partial least square regression (PLSR) model was established between ALI-convolved spectra....
East Africa (EA). The current poor capability of drought resistance and the high dependence local residents on agriculture animal husbandry initiated a comprehensive understanding soil moisture (SM) droughts in EA. Previous lower-order subspace investigations that have neglected space–time continuity actual hindered deeper knowledge droughts. To fill this gap, study investigated SM EA from joint perspective, focusing spatiotemporal patterns variations, climate drivers. Based approach, 582...
Polygala crotalarioides, a perennial herbaceous plant found in southwest China, has the potential to be used treatment of Alzheimer’s disease. Endophytic fungi that reside within medicinal herbs play an important ecological role their host plants and can serve as valuable source for identifying active components. However, little is known about diversity, structure endophytic P. crotalarioides. In this study, we investigated community diversity leaves, stems, roots crotalarioides at both 1-...
Capturing high frequency water surface dynamics via optical remote sensing is important for understanding hydro-ecological processes over seasonally flooded wetlands. However, it a difficult task due to the presence of clouds on satellite images. This study proposed MODerate-resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) Minimum Value Composite (MinVC) algorithm generate daily data at 250-m resolution. The selected pixelwise minimum values from...
Abstract Climate warming induces temporally varying atmospheric water vapor, yet the spatial distribution of opposing trends across global land remains elusive. Here we use monthly ERA5 dataset to discern responses vapor changes rising air temperatures from 1982 2020. Simultaneous increase in both and temperature over approximately three-quarters land, with a median 0.21 mm·K–1, particularly evident tropics. Strong positive are primarily influenced by increasing evapotranspiration...
ABSTRACT Rapid warming in northern lands has led to increased ecosystem carbon uptake. It remains unclear, however, whether and how the beneficial effects of on uptake will continue with climate change. Moreover, role played by water stress temperature control highly uncertain. Here, we systematically explored trend gross primary production (measured “ S GPP‐TAS ”) across (> 15°N) using a standardized multiple regression approach controlling other covarying factors. We estimated three...
Surface net radiation plays an important role in land–atmosphere interactions. The can be retrieved from satellite radiative products, yet its accuracy needs comprehensive assessment. This study evaluates monthly surface generated the Clouds and Earth’s Radiant Energy System (CERES) Radiation Budget project (SRB) respectively, with quality-controlled data 50 meteorological stations China for period March 2000 to December 2007. Our results show that is generally overestimated CERES (SRB), a...
Satellite remote sensing has accumulated decades of normalized difference vegetation index (NDVI) data. For long-term environmental studies, multisensor NDVI discrepancies should be initially corrected via intersensor calibration. This paper proposes a generalized model and its simplified form for the calibration by incorporating sensor-, atmosphere-, observational geometry-related parameters into an analytical function. The models are first validated using tandem Landsat-5 Thematic Mapper...
Abstract The effects of dams on carbon dioxide (CO 2 ) fluxes in downstream lakes remain elusive. Here we combined eddy covariance observations and random forest models to examine multi‐decadal variations CO the Poyang Lake, largest freshwater lake China, quantified contribution Three Gorges Dam (TGD), world's hydraulic project. We found fluctuated between source sink 1961–2016, tended be post‐TGD period (2003–2016) when vegetation expanded early spatially due declining water level. TGD can...
Near-surface, airborne, and satellite platforms can provide multisensor, multiscale normalized difference vegetation index (NDVI) data for spatially temporally continuous land-surface monitoring. This article presents a comprehensive literature review focused on consistency issues among these data, particularly in the spectral aspect.
Remote sensing and land surface models promote the understanding of soil moisture dynamics by means multiple products. These products differ in data sources, algorithms, model structures forcing datasets, complicating selection optimal products, especially regions with complex covers. This study compared different algorithms flagging strategies based on situ observations Anhui province, China, an intensive agricultural region diverse landscapes. In general, outperform remote terms valid...
Mangrove ecosystems can be both significant sources and sinks of greenhouse gases. The restoration mangrove forests is increasingly used as a natural climate solution tool to mitigate change. However, the estimates carbon exchanges remain unclear, especially from restored mangroves. In this study, we observed temporal variations in dioxide (CO2) methane (CH4) fluxes their biophysical controls for 4 years, based on closed-path eddy covariance (EC) system. measurements were conducted wetland...
Poyang lake wetland Evapotranspiration (ET) is a critical parameter in the hydrologic and energy budget, it important for understanding spatio-temporal variations ET large wetlands. Monthly Lake during 2008–2017 was estimated by remote sensing retrieval model based on Nonparametric approach (RS-NP). And variation of influencing factors were analyzed. The validation revealed usefulness RS-NP moist region yielded relative error 6 % (12 %) wet (dry) season. Temporally, average yearly 884 mm...
