Context
- Sandy lands in northwestern Liaoning Province face challenges in vegetation productivity.
- Understanding factors influencing vegetation is crucial for land management and restoration.
Purpose
- To identify key drivers of vegetation productivity in sandy lands at multiple scales.
- To quantify the relative importance of soil, topography, climate, and vegetation characteristics.
Summary
- A multi-scale analysis (regional, pixel, plot) using random forest models and correlation analysis was performed.
- Fractional vegetation coverage and leaf area index were the most significant factors, explaining 72.8% of net primary productivity variation.
- Topographical factors were the second most important, followed by climate and soil nutrients.
Impact
- Provides insights into vegetation dynamics in arid and semi-arid sandy ecosystems.
- Informs targeted strategies for enhancing vegetation productivity and ecological restoration in sandy lands.

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.
Plant cell cytoplasm has a high solute concentration, which causes water to flow from the soil into the plant due to osmosis. However, excess salt in the surrounding soil increases the soil solute concentration, reducing the plant’s ability to take up...
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
In land plants, the uppermost cell layer of a plant leaf, called the epidermis, is coated with a waxy substance called the cuticle. This hydrophobic layer is composed of the polymer cutin and...
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...
