Ecological Vegetation Restoration and Regeneration Technology of Abandoned Land for Remedying the Heavy Metals Polluted Soil

Abstract

Urban industrial wasteland may have been affected by the pollution of toxic and harmful substances produced by the original production activities, and the original ecosystem has been severely damaged. Especially in abandoned mines, the soil is heavily polluted by heavy metals and ecological restoration is extremely difficult. Chinese urban industrial wasteland has the characteristics of a huge number and diverse types of damage to the ecological environment. The elements of landscape design should be scientifically laid out from the three aspects of visual communication, history and humanities, and landscape structure. At the same time, attention should be paid to the external expression and internal culture of the landscape. Connotation, restoration and regeneration of landscape structures, topography, vegetation, and water bodies to create a new urban landscape space that combines ecological protection, landscape appreciation, educational science, and urban memory. For this reason, the thesis expounds the vegetation reconstruction in the ecological restoration of various industrial wastelands, and mainly analyzes the three links of soil substrate improvement, plant species selection and plant planting technology.
