Study on the Construction of Wetland Landscape Design Mode in Mountainous Cities Based on Green Infrastructure

Abstract

Green infrastructure is put forward to deal with the problem that the ecological service function of natural space is deteriorating in the process of urban expansion, that is, green infrastructure should be treated as the “infrastructure“ that all sustainable development must rely on. Different regional environmental conditions determine the design diversity and technical differences of urban green infrastructure, especially in mountainous urban areas with complex topography, fragile ecological environment and broken land suitable for construction. With the rapid advancement of urbanization and the expansion of construction land in China, the natural ecological environment of cities has been seriously threatened and destroyed. How to consider wetland, a special geographical unit which is more significantly restricted by natural environment, has become an important exploration direction of regional green infrastructure construction. This paper analyzes the related concepts of green infrastructure, and plans and designs the green infrastructure of wetland parks in mountainous cities, aiming at improving the level of urban landscape and providing reference for the construction of other wetland green infrastructure in the future.
