Land cover changes, especially excessive economic forest plantations, have significantly threatened the ecological security of West Dongting Lake wetland in China. This work aimed to investigate spatiotemporal dynamics forests region from 2000 2018 using a reconstructed monthly Landsat NDVI time series. The multi-type including conversion another land category, category forest, and (such as flooding replantation post-deforestation), categories before after change were effectively detected by...
Eucalyptus plantations are expanding rapidly in southern China owing to their short rotation periods and high wood yields. Determining the plantation dynamics of eucalyptus facilitates accurate operational planning, maximizes benefits, allows scientific management sustainable development plantations. This study proposes a sliding-time-window change detection (STWCD) approach for holistic characterization analysis between 1990 2019 through dense Landsat time-series data. To achieve this,...
Heavy metal stress in crops is a worldwide problem that requires accurate and timely monitoring. This study aimed to improve the accuracy of monitoring heavy levels rice by using multiple Sentinel-2 images. The selected areas are Zhuzhou City, Hunan Province, China. Six images were acquired 2017, concentrations soil measured. A novel vegetation index called sensitive (HMSSI) was proposed. HMSSI ratio between two red-edge spectral indices, namely chlorophyll (CIred-edge) plant senescence...
An effective satellite observation system is developed to retrieve the diatom concentration in freshwater ecosystems that could be utilized for understanding aquatic biogeochemical cycles. Although singular value decomposition-based retrieval model can reflect complicated dynamics, spatial distribution and temporal trend on a large scale, as well its driving mechanism, remain prevalently elusive. Based Google Earth Engine platform, this study uses Sentinel-2 MultiSpectral Instrument imagery...
ASTER thermal infrared (TIR) data are widely used to detect mafic–ultramafic rock and quartz-rich rock, several indices have been proposed based on emissivity features. However, TIR bands of radiance correlate highly with each other, which indicates that the independent information derived from different may be limited, what's more, radiance-at-sensor contain atmospheric effect temperature information, thus interfering availability these previously indices. In this study, we aim explain...
Karst rocky desertification (KRD) has become a major long-term problem for the ecological environment in karst areas of southwest China. The aim this study was to monitor and evaluate level Pingguo County, Guangxi Province, China, by tracking seasonal spectral changes rock vegetation cover. Landsat-8 Operational Land Imager (OLI) images field measurements were collected novel index (KRDI) constructed as an indicator based on greenness, humidity, brightness. Then, time-spectrum feature space...
The effect of nucleophiles on the gas-phase E2/SN2 competition is still not completely elucidated, despite its importance in chemistry. In current work, electronic structure calculations prototypical reactions X- + CH3CH2Cl (X = OH, F, Cl, Br, and I) are performed at MP2 level with aug-cc-pVDZ or ECP/d. effects competing E2 SN2 terms correlation between barrier height reaction energy, electronegativity X, bond length, charge distribution, proton affinity anionic nucleophile explored...
Ubiquitous competition of stereospecific E2 elimination versus SN2 substitution is central importance in chemical synthesis. Herein, we uncover how the nature leaving group affects intrinsic competing dynamics that remains largely unknown as opposed to its role reactivity. Results are presented for a prototype case fluoride anion reacting with ethyl chloride, compared iodide. Chemical simulations reproduce scattering signatures observed experiments and reveal direct stripping/rebound...
Resilience is the capacity of an ecosystem to respond and recover from damage or stress. It can inherently exhibit cycle feedback disturbed recovery process for a specified period. The current availability dense consistent time series satellite images holds promise monitoring forest resilience. aim this study establish resilience indicators using Landsat assess in response maximum disturbance magnitude hilly red soil region, Hengyang Basin, Southern China. To achieve this, area 1987 2017...
