On Earth, water accounts for more than 70% of the total area and is the basis for the existence and development of life. However, with the rapid development of industrialization, urbanization and population growth, water resources are facing severe pollution pressure. Therefore, water quality ecological monitoring is particularly important, which aims to conduct long-term, systematic, comprehensive and continuous observation and analysis of the ecological environment of water bodies through scientific methods and technologies, so as to provide a scientific basis for the protection and rational use of water resources. Below we will combine some practical cases to understand the importance and application of water quality ecological monitoring.
First, let's look at an example of lake water quality monitoring. In the past few years, the issue of cyanobacteria blooms in Taihu Lake in Jiangsu Province, China, has attracted much attention. Taihu Lake is the third largest freshwater lake in China and one of the important water sources in the Yangtze River Basin. However, due to overfishing, industrial pollution, and agricultural water use, the lake's water quality has deteriorated severely, leading to cyanobacteria blooms and blooms. In order to solve this problem, the relevant departments launched the "Taihu Lake Water Environment Comprehensive Management Action Plan" and invested a lot of money to establish the Taihu Lake water quality monitoring network. Through long-term water quality monitoring, researchers have discovered many key factors that affect the water quality of Taihu Lake, and proposed corresponding treatment measures to effectively improve the water quality of Taihu Lake.
Second, let's look at another case study of river water quality monitoring. In the United States, the Mississippi River is the longest river in the United States and an important source of water for agriculture, industry, and life in the United States. However, due to problems such as industrial sewage discharge and the use of agricultural fertilizers and pesticides, the water quality of the Mississippi River has seriously deteriorated, affecting the lives and production of residents living along its banks. To address this problem, the United States launched the Mississippi River Cleanup Program and established a Mississippi River water quality monitoring system. Through long-term water quality monitoring, researchers have identified the main sources of pollution in the Mississippi River and formulated a series of remediation measures to effectively improve the water quality of the Mississippi River.
Finally, let's look at an example of marine water quality monitoring. In the Maldives archipelago in the Indian Ocean, overfishing, tourism and global warming have led to a severe decline in water quality in Maldives waters, leading to widespread coral reef deaths. To address this issue, the Maldives** has launched the Maldives Marine Conservation Programme and established a water quality monitoring system for Maldives waters. Through long-term water quality monitoring, researchers have identified the main sources of pollution in the Maldives waters and proposed corresponding treatment measures, effectively improving the water quality status of the Maldives.
Through the construction mode of "data + platform + application", the ecological monitoring and supervision solution of the digital earth open platform supports the integration of multi-source data collection such as weather monitoring, marine monitoring, water quality monitoring, climate change, land surface ecology, atmospheric environment monitoring, natural disaster monitoring, etc., and at the same time enhances the ability of data analysis and data application, forms a multi-regional, high-timeliness, multi-element integrated service system for ecological environment monitoring and supervision, and supports the solution of ecological environment monitoring problems in a variety of thematic scenarios.
