ON THE WEATHER-YIELD SIMULATION AND MODELS IN CHINA

In this paper,the development of the studies on the weather-yield simulation and forecasting model in China is briefly reviewed,and the main features of the current development stage are presented.Moreover,through examples the technical characters,approaches and experimental results are detailedly described and discussed of several major statistical forecasting models,dynamic crop growth simulation and the satellite remote sensing methods to estimate crop yield.Finally,the line of further development and the applied field are pointed out.At the present time,in particular,using the above-mentioned modelling techniques to simulate and evaluate the possible impact of climatic variation on agricultural production and further on man's survival and activities are of a very practical significance as well as socioeconomic benefits.
