Coupling Development Situation of Agricultural Eco-economic System in LoessHilly and Gully Areas as Farmland is Returned to Forest (Grass) Land

open access: yesShuitu baochi tongbao, 2022
[Objective] The coupling coordination relationship and evolution trend of the agricultural eco-economic system in the loess hilly and gully regions was determined, in order to provide a basis for scientifically evaluating the ecological economic benefits

Mapping erosion-corrosion of carbon steel in oil exploration conditions : some new approaches to characterizing mechanisms and synergies [PDF]

open access: yes, 2010
Erosion by solid particles in oil/water slurries is a technologically important area. In such conditions, it is necessary to distinguish between the effects of the sand, aqueous environment, and the oil.

Influences of conservation measures on runoff and sediment yield in different intra-event-based flood regimes in the Chabagou watershed

open access: yesScientific Reports, 2021
The Loess Plateau in China has suffered severe soil erosion. To control soil erosion, extensive conservation measures aimed at redistributing rainfall, hindering flow velocity and intercepting sediment were implemented on the Loess Plateau. To accurately

Seed Pre-Soaking with Melatonin Improves Wheat Yield by Delaying Leaf Senescence and Promoting Root Development

open access: yesAgronomy, 2020
The effects of exogenous application of melatonin (MEL) on promoting plant growth and alleviating environmental stresses are already known, but the potential value in crop production is still poorly understood.

Single-Species Artificial Grasslands Decrease Soil Multifunctionality in a Temperate Steppe on the Qinghai–Tibet Plateau

open access: yesAgronomy, 2021
Artificial grasslands have been regarded as an effective method to improve grass production and quality, especially on the Qinghai–Tibet Plateau. Soil ecosystem multifunctionality (EMF) plays an important role in sustainable regional development. However,

Water-repellent soil and its relationship to granularity, surface roughness and hydrophobicity: a materials science view [PDF]

open access: yes, 2005
Considerable soil water repellency has been observed at a wide range of locations worldwide. The soil exhibiting water repellency is found within the upper part of the soil profile.

Prediction of aboveground grassland biomass on the Loess Plateau, China, using a random forest algorithm

open access: yesScientific Reports, 2017
Grasslands are an important component of terrestrial ecosystems that play a crucial role in the carbon cycle and climate change. In this study, we collected aboveground biomass (AGB) data from 223 grassland quadrats distributed across the Loess Plateau ...
