Abstract:Grain sustainable production is an important foundation in ensuring China's grain security.As one of the main output region of grain production,northeast China plays an important role in the strategy of national grain security. In this article,taking 110 counties of commodity grain bases as the cases,the comprehensive assessment index system of grain sustainable production ability was established.Basic characters and regional differences of grain sustainable production ability in northeast China were comprehensively examined by using the technique of factor analysis and software SPSS 13.0.And five spatial types were classified according to the results.The purpose is to provide scientific base for improvement of grain comprehensive production ability.
Keywords:grain sustainable production ability  factor analysis  classified analysis  Northeast China
