环渤海地区地域多功能空间分异与演化特征研究(英文)

Spatio-temporal Differentiation of County Multi-functions along the Bohai Rim in China

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。

Based on the definition of dominant functions as well as the building of multifunctionality evaluation index system and analysis models, the authors evaluated the functions of economic development, grain production, social security and eco-conservation. 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; eeo-eonservation 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 gravity center of grain production gradually concentrated on the plain agricultural areas, while the distribution of eco-conservation function hadn＇t change considerably.
