【摘要】 北京等大城市对其周边地区城市化辐射作用明显。选取顺义、平谷、门头沟三个不同城市化速度区域,研究建设用地扩展程度及其驱动力,为揭示各自扩展的空间分异特征和原因提供依据。研究得出,建设用地扩展规模及强度与区域城市化速度高低呈正相关;耕地是各个城市化水平区域建设用地的首要扩展来源。由扩展程度模型和集聚度模型评价看出,顺义以西南部国际空港和城市组团为核心,呈现出建设用地扩展空间集中、强度高、面积比例大的特征;平谷以平原区城市组团和山区风景旅游、特色观光农业区域发展并重,扩展程度较高但空间上相对扩散等特征;而门头沟区因其山区为绝对主体的自然条件及历史发展背景,建设用地扩展几乎集中于东部平原区域,集聚度高、扩展程度低、面积比重小。更多还原

【Abstract】 Metropolises,like Beijing,produce obvious radiation function to the areas around on urbanization. Based on the analysis of the degrees and driving forces of construction land expansion in the three areas of different urbanization speed - Shunyi,Pingu,and Mentougou,this paper tries to find out the reason and provide evidence for their spatial differential features.The result turns out that,there is a positive correlation between the growth scale and intensity of construction land and regional urbanization level;Cultivated Land is the main origin of construction land expansion in areas of different urbanization speed.Through the construction land expansion degree model and agglomeration degree model,it is found out that Shunyi concentrates on the development of the southwestern international airport and city groups,and as a result,the spatial distribution of construction land expansion in Shunyi is concentrated,the intensity is high,and the area proportion is high as well;Pinggu focuses on the development of city groups in the plain regions,landscape tourism in mountain areas,and special tourism agricultures, and then,its construction land expansion degree is high while its spatial distribution is more dispersive than Shunyi’ s;because of the mountainous characteristics and special development background of Mentougou, the cases of construction land expansion there mainly happen in its eastern plain,where its construction land’ s aggregation degree is high,but the expansion degree and area proportion is low.After that,the driving forces are analyzed by grey related degree analysis.更多还原
