Research on Wetland Landscape Design Strategies Based on Eco-Hydrological Restoration

Abstract

Wetlands, known as the "kidneys of the Earth," play irreplaceable roles in maintaining ecological security, purifying water quality, regulating climate, and flood/drought mitigation. However, with accelerating anthropogenic activities, wetland ecosystems face severe threats and damages, including water pollution, biodiversity loss, and degradation. This study constructs a "vegetation-topography-hydrology" three-dimensional collaborative restoration model and employs SWMM simulation and AHP analysis to identify key regulatory parameters for wetland landscape design. Results show that optimized design enhances water purification efficiency by 35% and increases the biodiversity index by 1.8 times. The proposed landscape hydrological regulation technology provides a quantitative solution for wetland ecological restoration. This paper systematically analyzes the characteristics and functions of wetland ecosystems, elaborates on the principles and methods of wetland landscape design strategies based on eco-hydrological restoration, and discusses practical applications through case studies. Findings demonstrate that this strategy effectively improves water quality, enhances biodiversity, and strengthens ecosystem stability and resilience, offering novel thoughts and approaches for wetland conservation and sustainable development.
