摘　　要：地理要素影响城市社会经济发展是经典地理学研究的重要内容之一,湖泊通过系统自组织力和人为干预影响周边城市经济的发展。将渤海看作一个巨大的湖泊,以环渤海地区3省2市为研究区域,基于"湖泊效应"和BASS模型构建理论体系,利用缓冲分析和非线性回归分析确定分层边界和圈层结构。结果表明:1湖泊对城市经济的影响呈现随距离增加先下降后上升最后大幅下降的趋势;2将环渤海地区分为核心区、重点区和边缘区,边界线依次为66 km、216 km和区域边界;3圈层结构特征明显:重点区中心城市与核心区港口城市形成双核结构;随着距离增加,从核心区、重点区至边缘区城市经济发展水平呈现倒"U"型结构。One of the significant contents of the classical geography research is the influence of geographic factor on the social economic development of the city. The lake impact the economic development of surrounding cities through the power of systematic self-organization and human intervention. The urban economic effect region is that the largest geographical range of central urban economic activity impact and promote the development of regional economy, and it represent the relationship between the top city and the other regional cities.The urban economic effect region is a economic region based on the objective economic connection between central city and surrounding region, the spatial organization of it reflects the competition of the city at all levels for the regional economic hinterland. The influence of lake on the temperature, precipitation and soil structure of the surrounding land is called the'Lake effect'. Regard the Bohai as a huge lake and three provinces and two cities of the Bohai rim as the study area, based on the'lake effect'and the BASS model construct the theoretical system, and ensure the hierarchical boundary and circle structure using the buffer analysis and nonlinear regression analysis. The results show that: 1) The influence of lake on the urban economy showed the tendency that decline first and then rise and sharply decline finally with the increase of the distance. 2) The Bohai rim is divided into the core area, the key area and edge area, the line of boundary were 66 km, 216 km and the boundary of the region successively; 3) The characteristics of circle structure was obvious that the central city of the key area and the port city of form the two-core structure; from the core area, the key area to the edge area, the development level of urban economic showed inverse 'U' type structure with the increase of the distance. Finally, the advantages and disadvantages of the model are discussed.
