Researches in this field have made a great contribution to the national economicconstruction, and environmental protection. This paper focuses on presenting the major progress andachievements in the sandy desertification research during the last 50 years, including the stages ofstudy on sandy desertification, background environment of sandy desertification and its changes,the conception, causes, process, monitoring and assessment of sandy desertification, the vegetationsuccession, landscape ecology, plant physiology, impacts on ecosystem, high-effective use of waterand land resources and sustainable development in sandy desertified regions, sandy desertificationcontrol models and techniques etc.展开更多

At present, environment, resources problems and sustainable development theory have infused new driving force into the wetland development. Since wetlands have huge ecological and environmental functions, they are paid more and more attention to by academic circles. The key field in wetland study at present is the natural process of wetlands, including hydrologic process, biogeochemical cycle process, and biological process, the relation between wetlands and global changes, wetland function evaluation and wetland rehabilitation. The paper reviews the main study progress of wetlands in China, analyses the present situation of wetland researches in China, and puts forward the main direction of wetland science researches in China.展开更多

Shortly after the founding of the People’s Republic ofChina a few studies were carried out to meet the demand for the establishment of windbreak andsandbreak forests, for example, the studies of moving sand dunes in Yulin. Jingbian and Dingbianregions of Shaanxi Province. However, the comprehensive study of desert science in China展开更多

Although clean air actions have been legislated by many nations to mitigate pollutants＇ emission with the aim of protecting the atmospheric environment, serious air pollution events are frequently observed in different regions, especially in developing countries. To best evaluate the effect of various control measures as well as the influence of various pollutants on the atmospheric environment, the levels, sources and sinks of the pollutants are needed to be comprehensively investigated. Since atmospheric environment involves multidisciplinary approach, scientists with different disciplines together can provide profound understandings about the atmospheric environmental problems. Sino-French Workshop on Atmospheric Environment is just one of such platforms to join scientists together for collaboration, exchange of experience and ideas.展开更多
