Study on the enhancement of ecosystem service function and sustainability planning of landscape gardening based on biomechanics

With the acceleration of urbanization and the impact of climate change, landscape gardening plays an increasingly important role in improving urban ecological environments, enhancing biodiversity and improving ecological service functions. Based on the principle of biomechanics, this paper discusses the strategy of enhancing the ecosystem service function of landscape gardening and proposes to optimize the sustainability of landscape gardening by means of multi-scale planning frameworks, ecological corridor construction, and microclimate regulation techniques. Through the implementation of biomechanical optimization practices in the study area, in this study, multiple technical methods were used for data collection to ensure the accuracy and reliability of the data. For monitoring plant growth, a regular sampling method was adopted to measure growth parameters (such as plant height, crown width, root depth, etc.) of plants in the study area on a monthly basis. In addition, high-precision meteorological monitoring equipment (such as temperature and humidity meters, anemometers, etc.) was used for continuous monitoring of microclimate conditions, with a data collection time span of one year, covering seasonal changes. Soil stability assessment quantifies soil stability and water management capacity through regular sampling of different soil types, using soil shear tests and water retention capacity tests. All data were processed using statistical analysis methods and combined with model simulations to validate the effectiveness of optimization strategies, ensuring the scientific and reproducible nature of research results. It was found that the optimization of vegetation configuration, soil structure and water flow management could significantly improve soil and water conservation capacity, wind speed regulation and microclimate regulation. The high density of vegetation not only enhanced the soil water retention capacity but also effectively reduced the wind speed and improved the local climate environment. In addition, the construction of ecological corridors and reasonable vegetation layout enhances the ecological connectivity and stability of the landscape. By evaluating the sustainability under different seasons, this paper further discusses how to dynamically optimize the landscape according to seasonal changes to ensure the stability of its long-term ecological service function.
