PROGRESS IN RESEARCH OF AGRO-METEOROLOGICAL DISASTERS IN CHINA IN RECENT DECADE

Agro-meteorological disasters restrict the fast and healthy development of agricultural production due to their high frequency and severe intensity. Agro-meteorologists in China attached great importance to the research on agro-meteorological disasters. A lot of progress in research on agrometeorological disasters has been made in past decade supported by national key projects and other program. The emphasis of research on agro-meteorological disasters in China are improving monitoring system and forecast services and building the system of risk assessment and prevention system in recent decade. Based on 3s technology and surface observation, the dynamic monitoring system of agro-meteorological disasters was built to monitor the emergence and development of agro-meteorological disasters the year round. Satellite remote sensing monitoring system was built and improved. The dynamic monitoring of Agro-meteorological disasters, such as drought, flood and cold damage has been carried out. The high altitude temporal and spatial difference prediction system of disaster monitoring was developed step by step, in which RS, GIS and GPS were integrated. The study on agro-meteorological disasters prediction included the further development of mathematic statistical forecast method, the primary study on combining agrometeorological models with climate models, the application of advanced technology, such as GIS and internet as well as the development of provincial agro-meteorological disasters prediction system. The risk assessment of agro-meteorological disasters has experienced two stages. The first was studying the technical method of disasters risk analysis before 2001and the second was researching the quantitative technical method of risk assessment to build technical system of risk analysis, followed assessment, assessment after disasters and strategies. The main achievement included the study on risk analysis, risk assessment, risk regionalization of assessment agro-meteorological disasters and agricultural drought assessment based on remote sense monitoring information. In recent years, the prevention technique agrometeorological disasters was studied by combining active prevention techniques of using agroclimate resource effectively and passive techniques of developing prevention medicines in China. The distinct achievement in study on agricultural drought and cold damage prevention techniques was build.
