摘要： 在快速城市化和主体功能区战略背景下，滨湖城市作为城湖共生体，具有湖泊生态系统和城市社会经济系统双重属性，既是中国新型城市化格局中最具活力和潜力的核心单元之一，又是湖泊生态环境问题集中激化的高度敏感区，保护与开发并重，发展与风险共存。以行政区划调整后将巢湖纳入内湖的新合肥市为例，借助GIS平台，运用单因子评价法和综合敏感性评价法构成城市生态适宜性评价的方法体系，以水域因子、坡度因子、湿地因子、覆被因子、灾害风险因子组建资源环境约束指标体系，将合肥市域划分为极高敏感区、高敏感区、中敏感区、低敏感区、非敏感区5 种资源环境承载类型区；基于反规划理念，构建滨湖城市空间增长模型，并划定作为城市扩展生态底线的刚性和弹性空间增长边界。在此基础上，统筹考虑城市空间资源环境保障能力、人口与用地规模，结合城市总体规划方案，明确城市空间扩展方向，科学划定城市近期、中期和远期的增长边界。该方法在中国滨湖城市的空间增长规模与方向、湖泊生态系统安保与开发、城市用地调控与优化组合以及城市规划方案的合理性评价方面可提供科学决策依据。

Abstract: Under the context of rapid urbanization and primary function area strategy, a lakeshore city, as a lake-urban symbion, has the dual characteristics of lake ecosystem and urban socio-economic system. The city is not only the most energetic and potential core unit in future urbanization framework, but also the highly sensitive region and the major harnessing region with a series of lake ecologic environmental problems. Therefore, the regional planning of this area has both development potential and high risk and should take both protection and development into consideration. This project focuses on researching the real problems which need prompt solutions during lakeshore city development. With new Hefei as an example, the main objective of this project is to examine the problems of lakeshore city development based on watershed resource environmental carrying capacity. It also explores the driving factors of city growing boundary, constraint mechanism and variation. Learning from the anti-planning concepts, this project delineates the urban spatial growing boundary through building an index system of resource and environment constraints and the spatial growing model of lakeshore city. Moreover, by applying the growing boundary and land use comparative model, this project delimits regulatory and control range and also proposes the optimal regulation and control pathway and effective spatial growing framework. Based on the major objectives, this project tends to provide scientific basis of decision-making on the spatial growing scale and direction, the protection and development of lake ecosystem, industrial spatial optimal combination, the improvement of human living environment and reasonable assessment of urban planning.

Key words: urban around lake, urban growth boundary, resources and environment carrying capability, optimal path, Hefei City
