生态适宜的城市发展空间分析方法与案例研究

综合运用生态功能区划方法和土地建设适宜性分析技术,基于地理信息系统平台建立了生态适宜的城市发展空间区域(生态主导功能区)的划分方法,依据生态保护原则和土地开发适宜度,将城市生态主导功能区划分为禁止、限制、优化和重点开发区4种类型.介绍了该方法在大连市的应用.结果表明,大连市禁止、限制、优先和重点开发区面积分别占全市域土地面积的56%、19%、12%和13%.

Ecologically feasible space for urban development: a methodology and case study on Dalian Municipality, Northeastern China

The ecological feasible space for urban development (ecological-oriented functioning zones) was established. Based on GIS methodology, combining an ecological function regionlization approach and a land construction feasibility analysis technique. Accordingly, urban development space could be divided into four types, consisting of forbidden construction zone, restricted construction zone, preferential construction zone and primary construction zone. The integrated method for a case study on Dalian Municipality, northeast of China showed that the areas of these four categories of Dalian accounted for 56%, 19%, 12% and 13%, respectively. The methodology was valuable for reducing ecological risks and environmental impacts of urban master plan and land use plan, and thus was relevant for promoting the national campaign of strategic environmental assessment.
