Plant landscape planning and design of Nanshan Botanical Garden (China) based on forest ecological garden

Abstract

Abstract In recent years, with the rapid development of human civilization, a variety of environmental problems have emerged. As the most important natural ecological system of terrestrial ecosystems, forest ecosystem plays a significant role in protecting the environment and beautifying cities. The landscape planning and design of botanical gardens is of great significance to the maintenance of the urban forest ecosystem. Taking the Nanshan botanical garden as the research object, this paper analysed the present situation of the garden and carried out the vegetation landscape planning transformation on it from the perspective of landscape ecology. Then, the landscape hierarchy analysis method was used to evaluate the landscape after the transformation, the results of which suggested that the comprehensive evaluation of the garden was the highest when the plant landscape was diversified and the structure level was reasonable, which provided a reference for the optimization of the urban forest ecosystem.
