Abstract [Background] The essence of soil erosion supervision is to adjust human behavior and correct human improper behavior to control soil and water loss. The work focus of China water and soil conservation has tended to soil erosion supervision since 2018, and the ability of public service and social governance has been improved obviously, but the contradiction between insufficient of soil erosion supervision and social demand is prominent day by day. [Methods] Based on the experiences and lessons of soil erosion supervision and research on monitoring of soil and water conservation, according to the demand for soil and water conservation in social and economic development, government decision and public activities, this paper comprehensively analyzed the meaning and work flow of soil erosion supervision, and put forward the targets and tasks of soil erosion supervision and its realization way. [Results] The targets of soil erosion supervision include exploring and discovering soil erosion and its influencing factors, evaluation and prediction soil loss and the harmfulness, demonstration on prevention and management of soil and water loss, supervision and law enforcement to prevent artificial soil loss. The soil erosion supervision contains seven tasks, which could be implemented by spatial organization, time organization and organizational implementation, and improvement of national standards, popularization and application of modern space technology, construction and application of information system and construction of supervision team can provide important technical support for the soil erosion supervision. [Conclusions] This paper point out that soil erosion comprehensive supervision should be a closed-loop system which consists of data acquisition and analysis and its application to soil erosion comprehensive supervision, all the tasks and technical support measures should make concerted efforts in promoting soil erosion supervision system becoming more mature, and this research can provide a reference for governments at all levels in soil erosion comprehensive supervision.
