Abstract Based on the spatial grid of the kilometer scale, the basic evaluation unit is constructed. The consistency evaluation of regional ecological carrying capacity and industrial layout are carried out. The Qingpu District of Shanghai is used as a research case. The results show that proposed method can effectively identify the regional ecological carrying capacity and the spatial distribution of industrial pressure, and evaluate the consistency of the regional ecological carrying capacity and industrial layout. The average industrial pressure index of Qingpu District is 0.51, and the ecological carrying capacity index is 0.25. The ecological carrying capacity of Qingpu district has a high consistency with the industrial layout, and the average consistency index is 3.12. Key words spatial grid; ecological carrying capacity; industrial pressure; consistency evaluation

承载力的概念来自物理学, 指物体在不产生任

[1]何破坏时所能承受的最大负荷 。20世纪 70年代开始, 由于能源枯竭、环境恶化等现象日趋严重,承载力概念广泛应用于环境、能源和经济等领域的

[2–9]研究中 。近年来随着研究的深入, 承载力的概念已应用于多个领域, 并产生生态承载力、环境承载力和土地承载力等概念。代表区域资源和环境子系统对社会经济、人口活动支撑和容纳能力的生态承载力研究一直备受国内外学者关注, 已成为区域

可持续发展的重要理论支撑[10]。

目前, 我国经济增速放缓, 但工业化和城镇化进程加快, 资源环境与经济发展的矛盾较为突出。为了解决区域发展面临的问题, 部分学者将产业发展与生态承载力相联系, 针对产业发展对生态承载力的影响、基于生态承载力评价的产业优化等问题展开研究, 探讨二者的相互作用[11–14]。生态承载力已成为区域产业发展的重要约束条件, 其大小决定一个地区的产业类型以及产业空间布局方式[15]。
