Special Issue Information

Dear Colleagues,

Vegetation is a collective term for various plant types that grow on the surface of the Earth and play an important role in the Earth's system. Vegetation is an important regenerative resource within the Earth's surface. Vegetation is the most active and valuable influencing and indicating factor in global change. It simultaneously affects the energy balance of the Earth’s atmosphere system and plays an important role in climate, hydrological, and biochemical cycles.

The combination of remote sensing technology and machine learning technology has brought new solutions to vegetation monitoring. The data obtained through remote sensing technology are automatically analyzed and processed through machine learning algorithms to achieve the efficient and high-precision monitoring of vegetation coverage, biomass, and pests and diseases. This is of great significance for environmental protection and ecological construction. This Special Issue will offer a comprehensive review of the research on the simulation and monitoring of vegetation biomass, vegetation coverage, vegetation phenology, vegetation diseases and pests, and vegetation ecological hydrology using machine learning or remote sensing technology. We kindly invite authors to submit review articles, original research articles, or short communications on topics related to the spatiotemporal change monitoring and driving mechanisms of grasslands, forests, and crops in the context of the application of machine learning or remote sensing technology. As Guest Editors, we look forward to reviewing your relevant contributions to this Special Issue. The specific topics of this Special Issue will include (but are not limited to) the following:

  • Vegetation remote sensing monitoring;
  • Vegetation biomass simulation;
  • Crop disease monitoring;
  • Crop yield prediction;
  • Analysis of vegetation driving mechanism;
  • Vegetation ecological hydrology.

Plant height and biomass are important indicators of rice yield. Here we combined measured plant physiological traits with a crop growth model driven by unmanned aerial vehicle spectral data to quantify the changes in rice plant height and biomass under different irrigation and fertilizer treatments. The study included two treatments: I—water availability factor (i.e., three drought objects, optimal, and excess water); and II—two levels of deep percolation and five nitrogen fertilization doses. The introduced model is extreme learning machine (ELM), back propagation neural network (BPNN), and particle swarm optimization-ELM (PSO-ELM), respectively. The results showed that: (1) Proper water level regulation (3~5 cm) significantly increased the accumulation of spike biomass, which was about 6% higher compared to that under flooded conditions. (2) For plant height inversion, the ELM model was optimal with a mean coefficient of determination of 0.78, a mean root mean square error of 0.26 cm, and a mean performance deviation rate of 2.08. For biomass inversion, the PSO-ELM model was optimal with a mean coefficient of determination of 0.88, a mean root mean square error of 3.8 g, and a mean performance deviation rate of 3.29. This study provided the possible opportunity for large-scale estimations of rice yield under environmental disturbances. Full article
