Abstract:

These years, agro-meteorological disasters are getting more serious by day and are jeopardizing China’s agricultural in an extending range. Governments and departments at all levels are paying special attention of the researches regarding disaster investigation and loss evaluation. As a result, it is essential that we have a standard of damage assessment for meteorological disasters. This paper has summarized the existing damage assessment methods and standards, including statistical methods and observation methods of the meteorological disasters. Besides, the paper introduces the grading rules of meteorological disasters which are being formulated. It points out that the grading rules are a combination of both agricultural standards and meteorological standards which will be conducive to the application of scientific research on the production practice. Meanwhile, it is helpful to departments at all levels to adopt scientific measures to take precautions against natural calamities and provide scientific evidence for evaluating, assessing, and overcoming agricultural loss.
