I. Project Background
Wetland is closely related to the reproduction, survival and development of human beings. It is one of the most important environmental capitals of human beings. It is also an ecosystem rich in biodiversity and higher productivity in the natural world. It has enormous economic, social and environmental value. In recent years, as one of the contracting parties to the “Wetlands Conventionâ€, the Chinese government attached great importance to the protection, development, and rational use of wetland resources, and even deployed a series of protection work.
However, due to the early days, people’s ignorance of the environment, the limitations of their understanding, and the pure pursuit of economic interests have long been a result of numerous factors such as cofferdams, infrastructure occupation, environmental pollution, over hunting, siltation, unreasonable water conservancy projects and many other factors. Under the superimposed effect, the wetland resources suffered severe and irreversible damage.
As a result, the wetland is a unique ecological environment formed by the interaction of hydrology, soil, atmospheric composition, and microclimate, and any change in the factors that make up this environment will lead to changes in the wetland ecosystem. Therefore, when it When disturbed by natural or human activities, the stability of the ecosystem is damaged to a certain extent, which in turn affects the structure of the biological community. Wetland ecosystems disappear, deteriorate, and degrade at a speed that is visible to the naked eye, causing great harm to the economy and society. sustainable development.
Therefore, on the basis of adopting protective measures for wetlands, a complete monitoring system for wetlands should be established to fully understand the dynamic changes of wetlands and provide timely and accurate reference materials for wetland management, scientific research, effective management and control, and rational use of wetlands. Maintaining ecological functions of wetlands and realizing sustainable economic development are of great significance. As a national wetland park approved for establishment by the State Forestry Administration for the purpose of protecting wetland ecosystems, rationally utilizing wetland resources, and conducting public education and scientific research on wetlands, it is also the “pioneer†of perfecting the monitoring system.

Based on the characteristics of the structures and functional areas of wetland ecosystems, the monitoring of wetlands will focus on the development of monitoring in terms of biology, ecology, limnology, hydrology, and environmental science. index. Seize the information flow, energy flow, material flow transmission and relatedness of each trophic level in the ecosystem, and focus on protecting endangered species, protecting species diversity, and protecting the integrity and structure of natural ecosystems. Eco-balance is more sensitive to ecological factors, taking into account social and economic factors. The specific contents include natural environment factors, dynamic changes in biodiversity, wetland development and utilization, and threatened conditions, changes in wetland management, socio-economic development around wetlands, and specific indicators specific to different wetland types.
