英文摘要：

Agricultural terrain structure is one of the most important contents in agricultural geography studies,the morphology change of which has the characteristics of succession and development in temporal,and constraints and proliferation in spatial.It has important sense for revealing the low of agricultural terrain structure change by studying the change course and development trend of agricultural terrain structure according to the historical context of regional agriculture development.In this paper,four stages of agricultural terrain structure change were classified according to the historical process of agriculture development in northeast China.Moreover,based on analysis of historical documents,the regional characteristics in each period were discussed by structural factors change of land use,agricultural economic and agricultural production.The results are as follows： first,the population and land development were mainly centralized in Liaohe basin before the end of the Qing Dynasty,and the producing structure of millet,wheat,beans and rice come into being;second,with immigration influx,large scale land development began from Liaoning and Jilin to northern Heilongjiang in the late Qing Dynasty,and the pattern of gain producing structure of southern bean and northern wheat come into being.Third,the agriculture developments come into a comprehensive development period in the Republican of China,the farmland increased speedily,and soybeans,sorghum,corn and millet become the main grain crops.Finally,under the intrusion of Japanese Puppet Regime,the land,grain production and agricultural economic suffered serious destroy,and the regional agricultural development felled into colonization.The further analysis showed that the population growth,agricultural policy reformation,rapid development of urbanization and transport network were the main influencing factors of agricultural terrain structure change in northeast China.
