中文摘要：

以2008年3项乡村地域功能态和2000—2008年3项功能的增长势作为指示指标,利用Matlab软件的SOFM程序进行环渤海地区乡村地域功能分区,为加快形成特色鲜明、优势互补、功能协同的乡村地域空间格局提供科学依据。通过修正最终划分为经济发展、粮食生产、生态保育三个主导功能区,并细化为13个功能亚区。经济发展主导功能区主要分布在大城市周边、渤海沿线以及交通干线附近,是区域的经济核心区和城镇化快速发展区,其功能定位是保持经济技术领先优势并优化空间布局。粮食生产主导功能区主要分布在平原集中区,粮食总产量和人均粮食占有量均处于较高水平,但经济发展缓慢;围绕主导功能定位建设高产、稳产、高效的＂大农业区＂,提升粮食综合生产能力。生态保育功能区集中分布在山地丘陵区,优先保障生态建设与修复的土地需求,生态唯先的组织生产、生活活动。

英文摘要：

With the enhancement of geographic differentiation and diversity of man-land areal system in the process of long-term economic growth and large-scale urbanization,rural functions show a clear trend of increasing diversification.For the differences of resource endowment,location condition,stage of economic development and developing strategic orientation,rural functions in various regions have significantly spatial heterogeneity and temporal variability.Based on the definition of dominant function as well as the building of multifunctionality evaluation models,this paper evaluated the functions of economic development,grain production and eco-conservation of rural area along the Bohai Rim in 2000 and 2008.Function ecostate in 2008 and function ecorole between 2000 and 2008 were selected as indexes,based on SOFM network model,the study area was finally divided into 3 regions of rural dominant function and 13 sub-regions,and then characteristics of each functional areas and development orientations were analyzed.With slow economic development and weak social security function,grain-oriented functional areas are mainly distributed in plain area,and their development orientation is to build core area of food production and agricultural advantages of industrial clusters,to improve food production capacity.Eco-conservation functional areas are concentrated in mountain areas and hill areas,in which eco-priority land use strategies and ecological compensation should receive special focus.
