| Abstract: | In this paper we investigate methods to acquire and incorporate geoscience knowledge,such as the way to transform geo-scientific knowledge into constraint or initial value of the models;then put forward a novel surface model of agricultural climate resources,which combine trend surface method with spatial interpolation.Based on the air temperature data covering the period from 1951 to 2002 observed in 735 stations which obtained from National Meteorological Information Center in China,the formulae included ... |
