The landscape design of this intelligent monitoring and optimization facility for human settlement environment and population health is based on the West Courtyard Park in Siyang County, Jiangsu Province as the design space carrier. The internal planning and design of the park has many important ecological nodes, including botanical garden, digital ecological exhibition hall, intelligent bird watching house and many intelligent monitoring stations. From the aspects of urban human settlements public environment and facility function and structure design and implementation of system technology design, this environment and facility design is based on the investigation of the needs and behavior habits of the users, combined with the knowledge and data of natural ecology, human needs, ergonomics, functions, materials, aesthetics and ergonomics, etc. to design the public environment and facility function and form, and focuses on the use of intelligent IOT scheme technology, start the basic data collection, processing and monitoring of many factors of natural and human environment and human health, and then optimize the improvement path of environment and health level according to data analysis. Such as screening target pollutants, determining the scope of environmental impact and population distribution, monitoring of pollution sources, environmental exposure monitoring, population health monitoring, population disease monitoring, human biological monitoring, pathogenic microorganisms, noise, light, soil dust, food, drinking water, indoor air, ambient air, emission monitoring, radioactive electromagnetic radiation, analysis and calculation of output pollution sources and source strength, environmental and health risk assessment, health impact assessment, analysis and calculation of output environmental and health testing reports and other historical and current data collection, processing and analysis, through on-site dynamic monitoring and data analysis, to obtain the implementation path of environmental and health optimization. Functions and attractions are the design, construction and use of landscape environmental facilities such as intelligent ecological biological environment, population health monitoring and human monitoring as the form of realization of the value of specific functional facilities. Digital ecological exhibition hall design. The ecological science popularization exhibition hall is all made of environmental protection materials. It has the characteristics of disassembly, easy transformation, convenient movement and convenient recycling. It is daily used as an ecological monitoring station and an ecological science popularization exhibition hall to display ecological science popularization to students, tourists and other groups. In special periods, it can be transformed into functional buildings such as temporary shelters and nucleic acid detection stations. Highlight the design concept of low-carbon environmental protection, so that the ecological science museum itself has become one of the important nodes of ecological design. The ecological pavilion consists of five major areas. The science and technology monitoring area combines the terminal platform in the museum and the internal monitoring device of the park to carry out real-time monitoring of the surrounding environment, ecology and population health of the park. The ecological classroom area explains ecological restoration and classic successful cases to students and tourists. Non-profit organizations or groups that are currently striving for ecological construction in the protection agency area. Sponge city exhibition area introduces sponge city treatment technology used in the park; the vision planning area explains the ecological development prospects of the future park, county area and even the whole country and the vision of ecological and healthy scientific and technological innovation.
