Sino-Norway: Observation and Research on the Integrated Effects of Acid Deposition in China

Project Background

The energy structure has greatly changed in the 20th Century world wide. However, the Chinese coal-dominated energy structure will not have substantial change in several years. The increasingly demand for coal and the holdings of car is bringing constant rising emission of acid deposition gas (SO2, NOX), which has caused not only enormous economic loss, but also the destructive encroachment of ecosystem, whenever the acid  (gas or aerosol) reaches the ground through dry and wet deposition. Thus, the acid deposition has become one of the biggest environmental problems in 21st Century, and is an important mission for China to control acid rain at present. In such a context, the Sino-Norway Cooperation Project was jointly launched by China’s Ministry of Environmental Protection, China’s Ministry of Commerce, together with Norwegian Agency for Development and Cooperation.
Project Objectives
To clarify the damages of acid deposition for providing basis of decision making in effect control of acid rain towards plant.
Project Partners
Chinese Research Academy of Environmental Sciences; Beijing University; Tsinghua University; Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences; Chinese Academy of Forestry Sciences; Beijing Normal University; People’s University of China; Guizhou Research Academy of Environmental Sciences; Hunan Research Academy of Environmental Sciences; Chongqing Research Academy of Environmental Sciences; Guangzhou Research Institute of Environmental Sciences; Norwegian Institute for Water Research; Norwegian Institute for Air Research; Norwegian Institute for Land Resource Research; Norwegian Institute for Forestry Research; Norwegian Institute of International Affairs; Agricultural University of Norway; University of Oslo.
Project Implementation
The project selects 3 acid rain observation points with internationally high standards, including Tieshanping plain of Chongqing City, Caijiatang of Hunan Province, and Leigong Hill of Guizhou Province, typical acid rain regions in southern part of China. Based on chemical and distribution features of acid deposition, the project uses standard sampling and chemical analysis methods recommended by EMEP monitoring network to do research on forestry ecosystem canopy leaching, sulfur and nitrogen deposition feature, acid deposition load, and environmental efforts. And acid deposition feature and pattern in typical acid rain area in southern China have also been investigated.
Project Achievements
Fount out current situations of China’s acid deposition, the influences of relevant factors towards the law of acid rain migration pattern, and the influence of acid deposition on plants; and the modeling of acid rain migration control.
