| Land resources are the material foundation that is inseparable and closely related to human survival and development.However,while the development of my country’s industrialization promotes urban renewal,due to the rapid development and expansion of cities and related political and economic reasons,many industrial plants and industrial ancillary facilities have been abandoned,resulting in a large amount of industrial wasteland.On the one hand,these industrial brownfields occupy valuable land resources;on the other hand,they also destroy the regional ecological environment and pose a threat to public health.Brownfields do not exist in isolation in the form of land.They often interact with the surrounding water and soil.Land pollution is transferred through the food chain,rivers,and groundwater.This poses a serious threat to many aspects of the human living environment,restricts the pace of the city’s progress,and hinders the sustainable development of society.Therefore,it is urgent to study how to treat and restore the pollution in brownfields.The thesis is divided into 7 chapters,the first chapter is the introduction.It mainly introduces the research background,studies the present situation,clarifies the research direction and content,and combs the research framework.The second chapter is related to basic concepts and theories.Through combing and interpreting the relevant concepts and theories of brownfield landscape,plant restoration and plant landscape in brownfield,and summarizing the influencing factors of phytoremediation in brownfield,the role and value of phytoremediation landscape in the restoration and transformation of industrial brownfield are clarified,which lays a theoretical foundation for the landscape design of phytoremediation in industrial brownfield.The third chapter is the analysis of excellent cases.This paper discusses the construction background of the project,the landscape design concept and the concrete measures taken by the transformation,and finally summarizes the plant landscape construction in the industrial brownfield transformation project according to the characteristics and different functions of the plant landscape.The fourth chapter is the study of plant restoration landscape types to reduce the environmental risk of industrial brownfield.The environmental risk situation of industrial brownfield was discussed,and the plant restoration mechanism was used to reduce the risk level and prevent the spread of environmental risk,and the application types of plant landscape were summarized to reduce the environmental risk of brownfield.The fifth chapter is the way of landscape construction of plant restoration in industrial brownfield.Based on the above research,the design principles of plant restoration landscape in industrial brownfield were formed,and the ecological restoration strategies for soil,water and waste site environment in industrial brownfield were put forward in detail in combination with the design principles and the characteristics of the restoration site.The sixth chapter is the transformation practice of Shaanxi Chenghua Company.The renovation design carries out the landscape design of the site according to the design principles and restoration strategies,and creates the brownfield landscape with ecological restoration function.The seventh chapter is the summary,draws the main conclusions of the paper,points out the shortcomings and innovations of this study.The research conclusions are as follows: First,the impact of environmental risks on risk receptors in brownfield can be reduced through the construction of plant landscape,and specific application types and specific measures of plant restoration landscape are proposed.Second,put forward the principles and strategies for landscape construction of industrial brownfield plant restoration under natural conditions in China. |
