Studying the spatiotemporal evolutionary characteristics of vegetation and effect precipitation changes is necessary for understanding regional ecological environment. We used trend analysis, partial correlation significance tests, residual analysis to analyze evolution driving factors fractional cover (FVC) in Jinghe River Basin (JRB) from 1998 2019. The results showed that coverage JRB significantly improved FVC an increasing 90.64% areas JRB, overall annual change was extremely significant (p ≤ 0.01). However, insignificant trend; distribution developed a uniform direction centroid tended move backward. area with between concentration index accounted largest proportion (18.47%). Precipitation generally favored recovery; however, limited non-precipitation dominated FVC. Our study contributes more comprehensive effects patterns on facilitate protection.

NDVI time-series data reconstruction for spatial-temporal dynamic monitoring of Arctic vegetation structure

Geo-spatial Information Science, Год журнала: 2024, Номер unknown, С. 1 - 19

Spatial-temporal dynamics monitoring of Arctic vegetation structure (i.e. distribution range tundra and forest) is great significance for evaluating global warming effect. Currently, time-series relies primarily on the Normalized Difference Vegetation Index (NDVI), which derived from optical remote sensing images. However, because factors such as long revisit period satellites impact climate, observations are severely lacking in region. This results NDVI data highly discontinuous difficult to reflect actual variations structure, traditional reconstruction method would usually fail severe missing conditions. Therefore, this study developed a Time Series Reconstruction considering Periodic Trend (TSR-PT), specifically alleviating observation condition It can separate phenological change trend incomplete time series NDVI, borrow information neighboring unchanged years compensate current years, based learned inter-annual intra-annual correlation. We explore its usability variation Vorkuta region (transition zone taiga Circle) MODIS data. found that proposed TSR-PT able reconstruct with reasonable feature even rate reaches over 70%, falsely constructed by filtering or fitting method, suppress them 0.038 terms RMSE; besides, we find since 21-century, trees have continued increase encroach original ecosystem, caused largely structural change, believe promote research.

Research on the Impact of Climate Change and Human Activities on the NDVI of Arid Areas—A Case Study of the Shiyang River Basin

Land, Год журнала: 2024, Номер 13(4), С. 533 - 533

Опубликована: Апрель 17, 2024

Arid zone ecosystems, integral to terrestrial systems, exhibit relatively low stability and are prone influences from human activities climate change. To elucidate the influence on ecological environment of arid by change activities, paper takes normalized difference vegetation index (NDVI) as an evaluation ecosystem uses trend analysis NDVI variation characteristics in Shiyang River Basin (SRB) 1990 2020. Simultaneously using methods such partial correlation residual evaluate impact changes. This study yielded several key findings: (1) The SRB exhibits increasing 0.034/10a interannual variation. (2) relation cooperatives between deviation precipitation temperature range −0.735 0.770 −0.602 0.773, respectively. (3) changes land use groundwater depth have a certain (4) proportion areas with significant contributions (contribution rate greater than 60%) is 33.5% 22.5%,
