چکیده
La variación temporal del índice NDVI predice los cambios temporales de la cobertura vegetal en las tierras secas Patagonia argentina. En secas, vegetación natural es una fuente importante sustento para comunidades que viven ellas, dado utilizan como alimento, combustible y forraje el ganado. Además bienes servicios brinda a comunidades, también juega un papel muchos procesos ecosistémicos, por ejemplo reciclaje nutrientes o protección suelo frente erosión. Por lo tanto, monitoreo largo plazo clave toma decisiones gestión estas regiones. este estudio, analizamos 239 sitios red (red MARAS), uno biomas más grandes mundo: estepa patagónica A continuación, relacionamos con diferentes períodos Índice Vegetación Diferencia Normalizada (Normalized Difference Vegetation Index, NDVI), obtenido sensor MODIS, sirve variable predictora. El modelo empírico ajustado explicó hasta 40% medida campo. Con sencillo hemos estimado cartografiado extenso bioma bajo coste.

monitoring of vegetation cover change in helen forested protected area and its causes based on bi-temporal analysis of ndvi
this paper aims to detect occurred changes in vegetation cover of forested helen protected area using extracted ndvis from bi-temporal multispectral images of landsat tm. to do so, at first forest areas with low and moderate density cover were identified and separated on land use map. then preprocessing applications including radiometric corrections were done on both 1990 and 2009 images. also ...
متن کاملLand-Cover Change Detection Using Multi-Temporal MODIS NDVI Data
Monitoring the locations and distributions of land-cover change is important for establishing links between policy decisions, regulatory actions and resulting land-use activities. Past activities including two-date change detection efforts using Landsat data have tended to be performance limited for applications in biologically complex systems. This study explored the use of 250 m multi-tempora...

The present study aimed to assess the spatio-temporal changes in the natural vegetation cover of Ahl Iman watershed, Ardabil province. For this purpose, land use maps of the three years (2000, 2010, and 2020) were extracted from Landsat satellite images. Then, seven landscape metrics (patch density, edge density, patch richness, splitting index, contagion index, Euclidean nearest neighbor dista...

متن کاملPlant species richness and shrub cover attenuate drought effects on ecosystem functioning across Patagonian rangelands.
Drought is an increasingly common phenomenon in drylands as a consequence of climate change. We used 311 sites across a broad range of environmental conditions in Patagonian rangelands to evaluate how drought severity and temperature (abiotic factors) and vegetation structure (biotic factors) modulate the impact of a drought event on the annual integral of normalized difference vegetation index...
