Improved SinGAN Integrated with an Attentional Mechanism for Remote Sensing Image Classification

open access: yesRemote Sensing, 2021
Deep learning is an important research method in the remote sensing field. However, samples of remote sensing images are relatively few in real life, and those with markers are scarce.

Relationships between tree and soil properties in Picea abies and Pinus sylvestris forests in Sweden [PDF]

open access: yes, 2010
The exchange of elements between plants and the soil in which they are growing creates reciprocal control of their element composition. Within plants, the growth rate hypothesis from ecological stoichiometry implies a strong coupling between C, N, and P.

Seasonal changes in dry matter yield from Karst pastures as influenced by morphoclimatic features [PDF]

open access: yes, 2018
Pastures are strongly affected by local environmental variables in terms of their species richness, plant composition and herbage production. A multi-site monitoring study was conducted over three years to investigate the influence of morphoclimatic ...

Refined Aboveground Biomass Estimation of Moso Bamboo Forest Using Culm Lengths Extracted from TLS Point Cloud

open access: yesRemote Sensing, 2022
Bamboo forest is a special forest type, and its aboveground biomass (AGB) is a key indicator of its carbon sequestration capacity and ecosystem productivity.

Recent advances in exploring physiology and biodiversity of ectomycorrhizas highlight the functioning of these symbioses in ecosystems [PDF]

open access: yes, 2000
Ectomycorrhizas, the dominating mycorrhizal symbiosis in boreal, temperate and some tropical forests, are formed by 5000-6000 species of the asco- and basidiomycetes.

Modeling the Relationships between the Height and Spectrum of Submerged Tufa Barrage Using UAV-Derived Geometric Bathymetry and Digital Orthoimages

open access: yesSensors, 2021
Tufa barrages play an important role in fluviatile tufa ecosystems and sedimentary records. Quantifying the height of tufa barrage is significant for understanding the evolution and development of the Holocene tufa barrage systems. However, for submerged

A physically based distributed karst hydrological model (QMG model-V1.0) for flood simulations [PDF]

open access: yesGeoscientific Model Development, 2022
Karst trough and valley landforms are prone to flooding, primarily because of the unique hydrogeological features of karst landforms, which are conducive to the spread of rapid runoff.

Effect of soil waterlogging on below-ground biomass allometric relations in Norway spruce [PDF]

open access: yes, 2010
An increasing importance is assigned to the estimation and verification of carbon stocks in forests. Forestry practice has several long-established and reliable methods for the assessment of aboveground biomass; however we still miss accurate predictors ...

Comparative Study on the Temporal and Spatial Evolution of the Ecosystem Service Value of Different Karst Landform Types: A Case Study in Guizhou Province, China

open access: yesApplied Sciences, 2022
Paying attention to the ecosystem service value (ESV) of different karst landform types is of great benefit to the green, sustainable, and high-quality development of the ecological environment in Guizhou Province.
