2000—2008年京郊农业圈层结构的时空演变

Temporal-spatial evolvement of suburban agricultural spheres structure in Beijing from 2000 to 2008

为揭示京郊农业区城乡统筹发展的机制,对2000年京郊农业区空间结构进行时空序列分析、产业结构演化分析;并对比了2008年京郊农业区发展的现状和已有研究成果。结果显示,京郊农业区的不同圈层因城乡功能的不同而具有不同的产业结构,京郊各区县的产业发展及城镇体系也因此而产生了空间分异。通过分析认为,2000—2008年京郊农业区的圈层结构虽然没有改变,但其产业基础却发生了较大变化,其中近郊平原农业圈受城市化影响其产业结构的空间变化较大;而远郊平原农业圈、山区生态涵养农业圈的空间变化相对较小,但其产业结构和农户行为都发生了不同程度的变化。

In order to reveal the mechanism of urban-rural harmonious development of Beijing suburbs, this paper conducted the analyses of temporal-spatial structure change and industrial structure evolution for agricultural suburban areas in Beijing, comparing the year of 2000 with 2008. Results showed that, a） spatial changes of the industrial structural characteristics have taken place in the suburbs; b） various spheres of the agricultural suburban area have different spatial industrial structures due to their urban-rural functions; and c） in terms of the town system and the industrial development, there were spatial variations between suburb counties in Beijing. This paper concluded that although change of circularity structure of agricultural suburban areas in Beijing was not significant from 2000 to 2008, its industrial foundation had changed significantly. Details were .as： a） industrial structure of agricultural areas in the plain outskirts have changed greatly under the effects of urbanization;b） in agricultural suburban areas of the plain as well as mountainous ecological conservation agricultural areas, spatial structure had changed only a little but their industrial structure and behaviors of the farmers have undergone various degrees of changes.
