Finite Element-Based Simulation Analysis of Wetland Plant Mechanics
Despite tidal action, which is influenced by sea level rise, having a substantial impact on plant communities, salt marsh plant communities in coastal wetlands also act as a coastal zone barrier.
Phragmites australis
and
Spartina alterniflora
were selected for the experiment in the Yellow River Delta wetland. The mechanical characteristics of the plants in the Yellow River Delta were investigated by field sampling, and the mechanical experimental data were used to simulate plant stresses under natural conditions using the ANSYS model based on finite element theory. The results are as follows: Assuming that the 2 plants have the same stem diameter, the deformation of
S. alterniflora
is greater than that of
P. australis
under both static tension and pressure conditions, confirming the phenomenon that the
P. australis
material has stronger strength resistance properties. When this model was applied to the force analysis in the natural state, it was discovered that the material strength attribute of
P. australis
is higher than that of
S. alterniflora
. From the perspective of morphology and structure, the stout stem of
S. alterniflora
can greatly alleviate the stress of itself under external force and greatly reduce the invasion effect of external force because field conditions are limited and do not reflect immediate mechanical feedback. The model simulation provides a way to accurately and efficiently obtain the mechanical action of plant body when discussing the mechanical action similar to wave action on plant stem and to explain some ecological phenomena from the perspective of mechanics.
期刊介绍:
Ecosystem Health and Sustainability publishes articles on advances in ecology and sustainability science, how global environmental change affects ecosystem health, how changes in human activities affect ecosystem conditions, and system-based approaches for applying ecological science in decision-making to promote sustainable development. Papers focus on applying ecological theory, principles, and concepts to support sustainable development, especially in regions undergoing rapid environmental change. Papers on multi-scale, integrative, and interdisciplinary studies, and on international collaborations between scientists from industrialized and industrializing countries are especially welcome.
Suitable topics for EHS include:
• Global, regional and local studies of international significance
• Impact of global or regional environmental change on natural ecosystems
• Interdisciplinary research involving integration of natural, social, and behavioral sciences
• Science and policy that promote the use of ecological sciences in decision making
• Novel or multidisciplinary approaches for solving complex ecological problems
• Multi-scale and long-term observations of ecosystem evolution
• Development of novel systems approaches or modeling and simulation techniques
• Rapid responses to emerging ecological issues.
