Research on Plant Landscape Design of Urban Industrial Site Green Space Based on Green Infrastructure Concept

With the acceleration of the global urbanization process, more and more industrial plants are being abandoned, which puts great pressure on urban ecology and land resource management. These abandoned industrial spaces not only lead to persistent pollution problems, but also exacerbate the urban heat island effect, leading to a worsening microclimate. To address these issues, the concept of green infrastructure (GI) has emerged as a sustainable ecological restoration strategy, and it is an important tool for urban renewal and industrial land transformation. In this study, the landscape environment of the industrial site of Henrichshutte in Germany and the surrounding industrial plant was taken as an example, and ecological restoration and plant landscape design were carried out using the GI concept. Two climate simulation tools, ENVI-met and WindPerfect DX, were comprehensively adopted to simulate the environment of the site in detail. Based on an analysis of the potential temperature, PMV, wind speed, and UTCI data of the site, it was demonstrated that the plant landscape improved the microclimate of the industrial plant. The results show that the reasonable allocation of plants can effectively reduce surface temperature and building temperature, increase air humidity, alleviate the local heat island effect, and enhance the thermal comfort of the human body. The simulation results highlight the practical application value of the GI concept in improving the ecological benefit, social function, and landscape aesthetics of industrial land. This study provides a new idea for the ecological restoration and environmental optimization of urban industrial land through the combination of green infrastructure and plant landscape design, and emphasizes the important role of green infrastructure in alleviating the urban heat island effect and promoting the sustainable development of urban landscape spaces.
