1. Overview of Environmental Monitoring Technology and Its Development Status
Environmental monitoring refers to the use of physical, chemical, biological and other technical means to systematically collect, analyze and evaluate the quality of the environment (air, water, soil, solid waste, etc.) and the emission of pollutants, so as to grasp the environmental quality status, track the changing trend of the environment and identify potential ecological risks. Environmental monitoring technology is the core carrier of environmental monitoring work, and its level directly determines the accuracy and efficiency of environmental governance and ecological protection.
1.1 Core Categories of Environmental Monitoring Technology
According to the monitoring object,
environmental monitoring technology can be divided into four major categories, forming a comprehensive monitoring system covering the whole environment:
- Air Environment Monitoring Technology: It mainly includes online continuous monitoring system (CEMS), portable air detection equipment, satellite remote sensing monitoring technology, etc., focusing on the detection of conventional pollutants (PM2.5, PM10, SO₂, NO₂, CO, O₃) and characteristic pollutants (VOCs, H₂S, etc.), realizing real-time monitoring of ambient air and industrial flue gas emissions.
- Water Environment Monitoring Technology: Covering online wastewater monitoring system (WWMS), offline laboratory analysis technology, underwater sensor network monitoring technology, etc., focusing on the detection of key indicators such as COD, BOD, ammonia nitrogen, total phosphorus, total nitrogen and heavy metals in surface water, groundwater and industrial wastewater, ensuring the safety of water resources.

- Solid Waste and Ecological Monitoring Technology: It involves solid waste leaching toxicity detection, solid waste online weighing and tracking technology, and ecological monitoring technologies such as vegetation coverage, biodiversity and ecological degradation, realizing the full-process monitoring of solid waste disposal and ecological environment changes.
1.2 Current Development Status of Environmental Monitoring Technology
In recent years, with the continuous advancement of science and technology and the increasing demand for ecological protection, environmental monitoring technology has made remarkable progress, but it still faces certain limitations. On the one hand, the traditional environmental monitoring technology is mainly based on offline sampling and single-point monitoring, which has the defects of long detection cycle, low real-time performance and limited monitoring coverage, and it is difficult to meet the needs of full-process, all-round ecological protection. On the other hand, although online monitoring technology has been popularized, there are problems such as poor data interoperability, low degree of intelligence and high operation and maintenance cost, which restrict the efficiency of environmental monitoring work.
Against this background, the integration of digital technology (Internet of Things, big data, cloud computing) and intelligent technology (artificial intelligence, machine learning) with environmental monitoring technology has become an inevitable trend, and the digital-intelligent transformation of environmental monitoring has become the key to breaking through the bottleneck of traditional monitoring and promoting the high-quality development of ecological protection.
2. Connotation and Core Technical Support of Digital-Intelligent Transformation of Environmental Monitoring
The digital-intelligent transformation of environmental monitoring refers to the integration of digital technology and intelligent technology into the whole process of environmental monitoring, including data collection, transmission, processing, analysis and application, so as to realize the digitalization of monitoring data, the intelligence of monitoring equipment, the networking of monitoring networks and the intelligentization of decision-making support. Its core goal is to improve the efficiency, accuracy and comprehensiveness of environmental monitoring, and provide more scientific and efficient technical support for ecological protection.

IoT technology is the foundation of digital-intelligent monitoring, which realizes the interconnection of environmental monitoring equipment, sensors and monitoring platforms through wireless communication technologies (4G, 5G, LoRa, WiFi). A large number of IoT sensors are deployed in the monitoring area to collect environmental data (such as pollutant concentration, temperature, humidity, water level) in real time, and transmit the data to the cloud platform through the network, realizing the full-coverage and real-time perception of the environment. This technology breaks the limitations of traditional single-point monitoring and builds a ""perception network"" covering air, water, soil and other environments.
2.1.2 Big Data and Cloud Computing Technology
Environmental monitoring generates a large amount of structured and unstructured data every day, including real-time monitoring data, historical data, meteorological data, and pollution source data. Big data technology realizes the storage, cleaning, integration and analysis of massive monitoring data, excavates the potential correlation and change law between data, and provides a basis for environmental decision-making. Cloud computing technology provides a flexible and efficient computing and storage platform for massive monitoring data, realizing the centralized management and shared application of data, reducing the investment cost of monitoring equipment and improving the efficiency of data processing.
2.1.3 Artificial Intelligence (AI) and Machine Learning Technology
AI and machine learning technology are the core driving forces for the intelligentization of environmental monitoring. By training the monitoring data, the AI model can automatically identify abnormal pollutant emissions, predict the changing trend of environmental quality, and realize the intelligent early warning of ecological risks. For example, the AI model can analyze the historical data of air pollutants, predict the concentration change of PM2.5 in the next few days, and provide early warning for air pollution prevention and control. At the same time, AI technology can also realize the intelligent diagnosis and self-maintenance of monitoring equipment, reducing the cost of manual operation and maintenance.
