Background
- The Luan River Basin (LRB) is a critical ecological barrier and water source for the Beijing-Tianjin-Hebei (BTH) region.
- Comprehensive research on Ecological Vulnerability (EV) evaluation and forecasting in the LRB is limited.
Purpose Of The Study
- To evaluate the spatiotemporal dynamics of Ecological Vulnerability (EV) in the LRB from 2002 to 2022.
- To identify the primary driving factors influencing EV in the region.
- To forecast future EV scenarios for the LRB by 2032.
Main Methods
- Ecological Vulnerability Index (EVI) was calculated using the SRP model with 17 indicators.
- Geodetector model was employed to analyze the driving factors of EV.
- CA-Markov model was utilized for EV scenario forecasting.
Main Results
- EVI increased from 0.397 to 0.428 between 2002 and 2022, with microscopic vulnerability being the most dominant type.
- Spatial analysis revealed a low-medium-high gradient of EV, with significant spatial clustering.
- Key driving factors identified include elevation, biological abundance, annual temperature, and cultivated land proportion.
Conclusions
- The study provides crucial insights into the ecological vulnerability dynamics of the LRB.
- Findings support evidence-based ecological policy-making for sustainable development.
- Balancing ecological conservation with economic growth in the LRB is essential.

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...
Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
Under normal conditions, water taken up by the plant evaporates from leaves and other parts in a process called transpiration. In times of drought stress, water that evaporates by transpiration far exceeds the water absorbed from the soil, causing plants to wilt. The general plant response to drought stress is the synthesis of hormone...
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...
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...
Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.
Practical constraints, however, can introduce geometric distortions, impacting how accurately these models represent the real system. Adjustments, such as...
Rapidly varying flow (RVF) in open channels is characterized by abrupt changes in flow depth over a short distance, with the rate of depth change relative to distance often approaching unity. These flows are inherently complex due to their transient and multi-dimensional nature, making exact analysis difficult. However, approximate solutions using simplified models provide valuable insights into their behavior.Key Features of Rapidly Varying FlowRVF is commonly observed in scenarios involving...
