Abstract [Background] The business requirements of dynamic supervision of soil and water conservation usually include three aspects:dynamic monitoring of regional soil and water loss, informatization supervision of production and construction projects and fine management of main projects. Due to the different requirements and purposes, the information and application results with different requirements are difficult to share, which brings difficulties to the unified supervision of water administrative departments at all levels. According to the business requirements of local government's dynamic supervision of soil and water conservation, and combining with the business logic and supervision experience of Ecological Environment Monitoring Station of Jiangsu Provincial Soil and water Conservation, the dynamic supervision analysis system of soil and water conservation was designed and conducted.[Methods] The system divides the minimum factor patch by multi-factor vector overlay analysis technology, and takes it as the supervision object. Through creating independent supervision task files for each supervision object, the task is assigned to the relevant responsible person in the region, and the task file circulation is used to promote and coordinate the implementation of specific supervision work of water administrative departments at all levels, so as to ensure all regulatory changes of task files information is transparently shared in the process.[Results] The experimental results of soil and water conservation monitoring stations in Jiangsu province show that the system takes districts and counties as the unit, it can integrate the monitoring and supervision data of three business scenarios in each district and county, and integrate the data results of different resolutions and frequencies in a hierarchical manner, so as to realize the whole process information sharing management of dynamic supervision of soil and water conservation; the minimum factor patch generated by overlay analysis can be used to realize the information sharing management of the whole process It can be implemented in the process of on-site supervision, and effectively drive the transfer of task files among users in different positions through user rights management.[Conculsions] The system improves the information management level of the comprehensive supervision of soil and water conservation of the local government in the three aspects, coordinates the task management of provincial, municipal and county-level regulatory departments, and improves the work efficiency of the comprehensive supervision.
