Ecological environment monitoring refers to the use of physical,chemical,biochemical,ecological and other technological means to monitor and test various elements in the ecological environment,the interrelationships between organisms and the environment,the structure and function of ecosystems.Ecological environment monitoring plays an important role in monitoring environmental pollution,protecting the ecological environment,ensuring public health,and promoting sustainable development.In order to achieve resource sharing and complementary advantages among ecological environment monitoring regions,and improve the accuracy and standardization of environmental monitoring data,this paper explored the Methods,technologies,and implementation paths of regional integration of information systems in the field of environmental monitoring from the perspective of ecological environment monitoring quality management.Based on practical cases,this paper elaborated on the implementation path and Methods,including how the contracting and construction units participate and cooperate,how to implement in stages,etc,provided a detailed introduction to the design concept,functions,and interrelationships of each module of the integrated system,and summarized the effectiveness and significance of regional integration in the inspection and testing industry which provides theoretical support for the reform and innovation in the field of ecological environment monitoring.
