摘要：
It is important to apply impervious surface product to the study of urban agglomeration spatial structure. Under the background of China's rapid urbanization, study on comparative analysis of urban agglomerations spatial structure between China and USA can provide policy proposals of urban agglomeration space optimization for Chinese government. Taking Beijing-Tianjin-Hebei (BTH) and Boswash as study areas, firstly, this paper maps the extent and density of impervious surface for BTH and Boswash respectively in seven periods of 1972, 1982, 1991, 1995, 2001, 2006 and 2011. Furthermore, at different scales of urban agglomeration and metropolitan region, landscape pattern index, gravitational index and spatial analysis were used to analyze differences of spatial structure between BTH and Boswash. The results showed that (1) impervious surface area increased rapidly in BTH, while it remained stable in Boswash. (2) BTH spatial structure had experienced different periods including isolated city development, dual-core city development, group city development and networkstyle city development, while Boswash spatial structure was more stable, and its spatial pattern had shown a "point-axis strip" feature. (3) The spatial pattern of high-high assembling region of impervious surface had showed a "standing pancake" feature in BTH, while a "multi-center gather and disperse group" in Boswash. (4) All of the percentages of impervious surface area in ecology, living, and production land in BTH were higher than those in Boswash. At last, from the perspective of urban agglomeration space optimization, the development proposals for BTH were proposed. © 2017, Science Press. All right reserved.
