Special Issue Information

Dear Colleagues,

In the context of climate and environmental change, the study of vegetation phenology in ecosystems has assumed increasing significance, particularly in the pursuit of the 2030 Agenda for Sustainable Development Goals (SDGs). Currently, the monitoring of vegetation phenology in a changing environment relies heavily on field recordings and limited remote sensing data. This reliance leads to inefficiencies in data analysis, a lack of coherence in modeling, diminished reliability, and unsustainability in diverse environmental conditions.

Emerging as a key information technology science in recent years, remote sensing (RS) big data offers a promising avenue for addressing these challenges. Leveraging database platforms, information services, and reanalysis modeling, RS big data enables more scientific and quantitative approaches to vegetation phenology analysis, spanning from landscape to crown levels. This Special Issue seeks to bridge the gap between remote sensing big data and field observations/recording. We intend to employ cutting-edge technologies such as satellite imagery, airborne remote sensing, and big data analytics to construct robust vegetation phenology analysis models. Ultimately, our goal is to furnish decision-making tools for scientists engaged in the study of vegetation ecosystems.

We invite researchers to contribute their original research papers, technical reports, or review articles to this Special Issue, with a particular emphasis on the applications and prospects of remote sensing in the field of vegetation phenology, such as:

  • Vegetation phenology detection and modeling;
  • Remote sensing / big data for vegetation phenology monitor;
  • Vegetation phenology change;
  • Vegetation cover and green spaces change;
  • Response of vegetation phenology to climate change and human activity;
  • Effect of vegetation phenology on ecosystem environment.

We look forward to receiving your original research articles and reviews.

Climate change inevitably affects vegetation growth in the Tibetan Plateau (TP). Understanding the dynamics of vegetation phenology and the responses of vegetation phenology to climate change are crucial for evaluating the impacts of climate change on terrestrial ecosystems. Despite many relevant studies conducted in the past, there still remain research gaps concerning the dominant factors that induce changes in the start date of the vegetation growing season (SOS). In this study, the spatial and temporal variations of the SOS were investigated by using a long-term series of the Normalized Difference Vegetation Index (NDVI) spanning from 2001 to 2020, and the response of the SOS to climate change and the predominant climatic factors (air temperature, LST or precipitation) affecting the SOS were explored. The main findings were as follows: the annual mean SOS concentrated on 100 DOY–170 DOY (day of a year), with a delay from east to west. Although the SOS across the entire region exhibited an advancing trend at a rate of 0.261 days/year, there were notable differences in the advancement trends of SOS among different vegetation types. In contrast to the current advancing SOS, the trend of future SOS changes shows a delayed trend. For the impacts of climate change on the SOS, winter Tmax (maximum temperature) played the dominant role in the temporal shifting of spring phenology across the TP, and its effect on SOS was negative, meaning that an increase in winter Tmax led to an earlier SOS. Considering the different conditions required for the growth of various types of vegetation, the leading factor was different for the four vegetation types. This study contributes to the understanding of the mechanism of SOS variation in the TP. Full article
