城市化改变了自然环境的组成,许多森林草地被大量建筑物所取代,破坏了大自然的自我调节,严重影响了自然环境的生态功能,引发了严重的自然。如随着城市化的快速发展,水泥道路铺设的越来越多,不渗透面积逐年增加,导致城市的水环境和水循环发生了改变,如下渗减少,地表径流增加等,这都更易引起洪涝灾害的发生,而城市发展必然会导致城市风景园林的增加。如何在城市风景园林的设计中加入新型雨洪控制利用技术,变废为宝,让多余的地表径流为城市风景园林所用,既为风景园林的建设节约了成本,又解决城市内涝问题,可谓一举两得。那么如何将新型雨洪控制利用技术运用到城市风景园林建设中,将城市风景园林建设与新型雨洪控制利用巧妙结合起来,是我们下文研究的重要课题。
Urbanization has changed the composition of the natural environment. Many forest and grasslands have been replaced by a large number of buildings, destroying nature’s self-regulation, seriously affecting the ecological functions of the natural environment and triggering grave nature. For example, with the rapid development of urbanization, more and more cement roads are laid and the impervious area increases year by year, resulting in changes in the urban water environment and water cycle, such as less seepage and increased surface runoff, which are more likely to cause floods The occurrence of urban development will inevitably lead to an increase of urban landscape architecture. How to add new rain flood control and utilization technology into the design of urban landscape garden and turn waste into treasure so that excess surface runoff can be used for the urban landscape garden, which not only saves the cost for the construction of landscape garden but also solves the urban waterlogging problem, . So how to use the new rain flood control and utilization technology to the construction of urban landscape architecture, the city landscape architecture and new rain flood control and utilization of clever combination, is an important issue for our study below.
