In order to reveal the spatial pattern of characteristics of major grain producing areas planting eco-economic system input and output emergy, and promote the changes from traditional agriculture to ecological agriculture, this paper has taken the state grain-producing area—Hebei Province as a study area. Based on emergy theory and spatial analysis techniques, it estimated the main input-output emergy indices of plantation industry of the 138 counties in Hebei Province. From the perspective of geography, this paper focused on the differences of spatial pattern of every emergy indicator and distribution trend. The results show: 1) The input and output emergy indices of planting eco-economic system showed significant geographical features. 2) The high value of emergy investment ratio (EIR) was mainly distributed in Shijiazhuang-Tangshan-Qinhuangdao, averaging 15.81, which showed large regional differences. 3) The high values of energy yield ratio (EYR) mainly distributed in the Xingtai and southeastern part of Handan, with coefficient of variation being 0.820. 4) The input and output emergy indices of planting eco-economic system showed spatial distribution of "U" type, inverted "U" type , first-order type etc. Finally, based on scientific analysis of the regional plant eco-economic system input-output emergy spatial difference characteristics, suggestions and countermeasures, such as large-scale operation, scientific adjustment of cropping structure which can improve the efficiency of emergy are proposed.
