Sensitivity Analysis And Its Control Regional Of Ecological Environment In Luobei County

In recent years,with the rapid development of China's economy,the state has attached increasing importance to environmental protection.How to handle the relationship between social-economic development and environmental protection governance has become the focus of environmental protection departments.In 2017,the Ministry of Environmental Protection proposed to carry out a regional space ecological strategic environmental impact assessment,which is detailed at the provincial,district,and county levels in units of provinces,referred to as "three lines and one order".The "three lines and one order" work is mainly to divide the ecological environment area according to the province area,and define three red lines,that is,the red line for ecological protection,the online use of resources,and the bottom line for environmental quality.The province-city-county district-by-region management is implemented It is planned to increase the management and control efforts of various government functional departments,make the economy and environment develop harmoniously,and realize the sustainable development of the urban regional environment.The thesis mainly focuses on the current inefficiency of environmental protection in counties and cities,and focuses on the "three-line,one-single" working method proposed by the state,and proposes how to divide and control the ecological environment area.Luobei County was selected as the target of the management and control subdivision.After fully understanding the local geographic profile,ecological environment status,population and economic development status,the ecological environment sensitivity analysis was carried out on the county scale.The environmental functions are combined with each other,and the Luobei County eco-environmental management and control subdivision is divided,and the management and control requirements are put forward according to the relevant specific conditions.The specific thinking steps are as follows:(1)Collect existing data,consult a large number of relevant literature,conduct local field surveys,and Experts and teachers conducted discussions and selected six environmentally sensitive factors based on the collected data,namely elevation,slope,water system,land use type,vegetation coverage,and soil erosion,and carried out ecological environment sensitivity assessment.(2)Combined with the analytic hierarchy process,GIS data analysis method,RS remote sensing interpretation method,GPS positioning technology,and using professional analysis software such as ENVI,BIGMAP,MATLAB,etc.,the maps are stacked to obtain a comprehensive evaluation map of ecological environment sensitivity.(3)Combining relevant planning documents such as land use planning and environmental function planning,and using the spatial overlay function of GIS to divide Luobei County's environmental management and control subdivisions,and in accordance with the requirements of the "Environmental Access Checklist",regulate the different subdivisions.The corresponding unit of the proposed control requirements.Provide scientific management measures and protection recommendations for the realization of sustainable development in Luobei County.Innovation manage and control the ecological environment at the county scale,and propose corresponding regional control requirements,combined with regional geographic information systems and map image interpretation software,to achieve precise regional management and control,and to optimize the use of social resources and technological innovation.The study on the division and control of regional ecosystems is not only conducive to the harmonious development of China's ecological environment and socioeconomic development,and the relationship between coordinated development and the bottom line.It can also realize the linkage of regional ecological data sharing and contribute to the country's future management and development.
