An Analysis of Spatial–Temporal Evolution and Propagation Features of Vegetation Drought in Different Sub-Zones of China

open access: yesAgronomy, 2023
The vegetation drought phenomenon will reduce the amount of water available to the vegetation system, change the ecological and hydrological cycles of plants, and affect the aquatic and terrestrial ecosystem in various forms.

Contribution of karst ecological restoration engineering to vegetation greening in southwest China during recent decade

open access: yesEcological Indicators, 2021
General greening in vegetation, especially in southwest China, has been observed globally in recent decade. However, temporal-spatial variation patterns and potential causes of vegetation greening are not well understood in southwest China. Here, we used

Remote sensing and geobotanical prospecting in Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1979
Visible and near infrared radiation is reflected from vegetation and open vaters in Finland in summertime. Thus the variation in the intensity measured is primarily an informant of the variation in vegetation. Indirectly it is also a geological informant

Linear trends in seasonal vegetation time series and the modifiable temporal unit problem [PDF]

open access: yes, 2012
Time series of vegetation indices (VI) derived from satellite imagery provide a consistent monitoring system for terrestrial plant productivity. They enable detection and quantification of gradual changes within the time frame covered, which are of ...

Impacts of trait variation through observed trait–climate relationships on performance of an Earth system model: a conceptual analysis [PDF]

open access: yesBiogeosciences, 2013
In many current dynamic global vegetation models (DGVMs), including those incorporated into Earth system models (ESMs), terrestrial vegetation is represented by a small number of plant functional types (PFTs), each with fixed properties irrespective of ...
