Abstract: In the case of developmental zone along Taizhou River, the authors added two important indicators (ecological footprint analysis and ecological service value) into evaluation system for improving the evaluation framework. Single factor assessment with GIS/RS technology was carried out, of which this two factors on the ecological suitability classification was mainly discussed. Weights of all factors were determined by hierarchical analysis. Finally, map of ecological suitability assessment of urban land use could be generated through overlaying of all single factor assessment layers, making the ecological suitability classes more scientifically and obtaining urban land constructiveness. The results show that the approach with ecological footprint and ecological service functions value as important indices is quite necessary for the ecological suitability classification, and the result is more reasonable and suitable for the regional sustainable development.

摘要： 以台州市沿江带为例,在评价指标体系中增加了生态足迹分析和生态服务价值两个重要指标, 进一步完善了评价框架。应用 GIS/RS 等技术方法, 评价了研究区的城市用地生态适宜性, 并进行单因子生态适宜度评价, 重点探讨了这两个因素在生态适宜性评价中的作用。通过层次分析法确定评价因子权重,最后叠加生成综合的城市用地生态适宜度分布图, 从空间上更加科学地表征土地利用生态适宜等级,从而得出城市用地的可建设性。结果表明,将生态足迹和生态服务功能作为重要指标进行城市用地生态适宜性分区研究,更具有针对性,分区结果更加合理,有助于地区的可持续发展。
