Automatic Grassland Degradation Estimation Using Deep Learning [PDF]

Proceedings of the Twenty-Eighth International Joint Conference on Artificial Intelligence, 2019
Grassland degradation estimation is essential to prevent global land desertification and sandstorms. Typically, the key to such estimation is to measure the coverage of indicator plants. However, traditional methods of estimation rely heavily on human eyes and manual labor, thus inevitably leading to subjective results and high labor costs. In contrast,

Self‐Adaptive Non‐Flammable Wallpaper With Layered Bead‐Network Structure for Light Path Modulation Enabling on‐Demand Building Thermal Management

Advanced Science, EarlyView.
A layered bead‐network wallpaper is designed to modulate the light propagation path, overcoming the color residue limitations of thermochromic components for efficient automatic switching between radiative cooling and solar heating modes. The layered bead‐network wallpaper provides passive, all‐season thermal regulation while offering self‐cleaning and

Changes in plant species richness distribution in Tibetan alpine grasslands under different precipitation scenarios [PDF]

, 2020
Species richness is the core of biodiversity-ecosystem functioning (BEF) research. Nevertheless, it is difficult to accurately predict changes in plant species richness under different climate scenarios, especially in alpine biomes.

Restoration prospects for Heitutan degraded grassland in the Sanjiangyuan [PDF]

Journal of Mountain Science, 2013
Abstract In many ecosystems ungulates have coexisted with grasslands over long periods of time. However, high densities of grazing animals may change the floristic and structural characteristics of vegetation, reduce biodiversity, and increase soil erosion, potentially triggering abrupt and rapid changes in ecosystem condition.

Theory and application of no-tillage reseeding in degraded grasslands [PDF]

Chinese Science Bulletin, 2020
There are 400 million hectares of grasslands in China, accounting for about 40.7% of the Chinese territory, which provide fundamental ecological and economic benefits. However, more than 90% of this grassland ecosystem is threatened by degradation. This leads to the loss of biodiversity and a decrease in ecosystem functions, such as productivity, soil ...
