- The State Forestry Administration carried out the Second National Wetland Resources Survey from 2009 to 2013.

The inventory showed that the total wetlands across the country reached to 53.6026 million hectars with the wetland rate of 5.58%. Compared to the First National Wetland Resources Inventory, wetlands had been reduced by 3.3963 million hectars with a reduction rate of 8.82%. Natural wetlands reached to 46.6747 million hectars, which accounted for 87.08% of the total wetlands across the country. Compared to the First National Wetland Resources Inventory, natural wetlands had been reduced by 3.3762 million hectars with a reduction rate of 9.33%.

- Wetland monitoring and evaluation
Evaluation on the ecological status of important wetlands in the world was launched in 2008. 45 Wetlands of International Importance were evaluated in China mainland. It’s the first time to evaluate ecological status of all Wetlands of International Importance in the country. The results show that the comprehensive health index of wetland ecological status in China is 6.06 with middle healthy level, and the comprehensive function index of wetland ecological status is 7.00 with good function level. Wetland ecosystem value is relatively high with the total value of RMB 266.831 billion yuan per year and the unit wetland value of RMB 114,200 yuan hectare per year.
- Investigation of peatland carbon reservoirs
In order to give full play to the role of wetlands in response to climate change, the State Forestry Administration started the investigation of peatland carbon pool of key provinces across the country in 2014, which is a practical action that China fulfills the United Nations Framework Convention on Climate Change and the Convention on Wetlands.

- Support of science and technology
Established in 2009, the National Wetland Science and Technology Committee composed of nine academicians is responsible for providing advices and recommendations on major policy decisions of national wetland protection and management as well as major issues of wetland scienctific development, and on the major scientific and technological problems encountered in the implementation of Convention on Wetlands. It is responsible for providing consultancy on the investigation, evaluation and decision-making for tackling key problems in wetland technologies, developing, promoting and introducing wetland technologies projects and major development programmes.
