基于可开发度指数的石家庄主体功能区划分评价研究

Shijiazhuang Development Priority Zoning Evaluation Study

生态环境保护和土地开发利用之间的矛盾是中国城市化进程中的主要矛盾。研究利用GIS空间分析方法,在潜力—阻力模型的基础上,将影响因子分为生态潜力和生态阻力两大类,构建可开发度指数公式,创建一套主体功能区划分评价的综合指标体系,运用多种权重确定与空间叠加方法,得到区分开发类和保护类片区的关键分界点;同时,运用情景分析法,以石家庄市为例,提出了以保护为主和以开发为主的两种城市发展模式,保证了空间管制与开发的科学性,为研究区生态环境保护和经济产业布局提供了参考依据。

Ecological environment preservation and land use is a major contradiction in China＇s urbanization process. The paper uses GIS spatial analysis method, potential-resistance model, development index equation, evaluation indices system, and multiple weighting methods to get the key points between development and preservation zones. The paper raises two development methods that guarantee the rationale of preservation and development for Shijiazhuang city. It provides a guideline for the zone＇s ecological environment preservation and industrial layout.
