Major findings are summarized as follows. 1) In 2008, economic-oriented functional areas were mainly distributed in Beijing-Tianjin-Tangshan region, Shenyang Metropolitan area, Jiaodong Peninsula and other municipal districts; grain-oriented functional areas were mainly distributed in central plain of Liaoning, western plain of Shandong, piedmont plain of Taihang Mountain and alluvial plain of Haihe River; the spatial pattern of social security function was closely related to that of economic development; eco-conservation functional areas were concentrated in eastern mountain areas and northwest hill areas of Liaoning, and northeast mountainous-hilly areas in Hebei. 2) Compared with 1990, the indices of multi-functions demonstrated an upward trend, and functions of economic development and social security have been improved significantly. The increasing degree of grain production function was smaller with the
