通过构建多功能性评价指标体系和指数分析模型,开展了环渤海地区1990年和2008年的经济发展、粮食生产、社会保障、生态保育及综合功能的分级评判。结果表明:2008年,经济发展功能一级区主要分布在京津唐地区、沈阳都市区、胶东半岛、鲁中地区、城市辖区及周边县域;粮食生产功能一级区主要分布在辽宁中部平原、鲁西平原、太行山山前平原和海河冲积平原;社会保障功能与经济发展功能指数的空间分布基本一致;生态保育功能强势区集中分布在辽东山地区、辽西北低山丘陵区、冀东北山地丘陵区。与1990年相比,环渤海地区县域多功能均呈现上升趋势,其中经济发展功能和社会保障功能迅速提升;粮食生产功能提升幅度较小,粮食生产重心进一步向平原农区集中;生态保育功能变化不显著,北部山地丘陵区的生态保育功能进一步凸显。
Through the construction of multi-functional evaluation index system and index analysis model, the grading judgment of economic development, grain production, social security, ecological conservation and comprehensive functions in the Bohai Rim region in 1990 and 2008 was carried out. The results showed that in 2008, the first level of economic development was mainly distributed in Beijing-Tianjin-Tangshan area, Shenyang metropolitan area, Jiaodong peninsula, Luzhong area, urban area and the surrounding counties; the first-level grain production function areas were mainly distributed in the central plains of Liaoning, Lushui plain, Taihang mountain piedmont plain and Haihe alluvial plain. The spatial distribution of social security function and economic development function index are basically the same. The strong ecological conservation function areas are concentrated in the Liaodong Mountain area, the hilly area in the northwest of Liaoning, the mountainous hills in the northeast of Hebei Area. Compared with 1990, the multi-functionalities in the Bohai Rim region have shown an upward trend. Among them, the function of economic development and social security have been rapidly improved; the function of food production has been less enhanced; the focus of grain production has been further concentrated on the plain farms; the changes in the functions of ecological conservation Not significant, the ecological protection in northern hilly areas further highlights.
