珠三角绿道网的建设规模与评价模型研究

摘要

珠三角绿道是中国绿道建设的初步实践，也是珠三角建设宜居城乡的重要途径之一，它覆盖了珠三角整个区域，发挥综合功能效益，实现城乡一体。通过总结国内外相关建设经验与研究方法，对绿道网络化的关键问题，即不同类型的珠三角绿道网络的选线密度及建设规模进行研究，并提出绿道建设评价模型，为更合理、科学地进行绿道网络规划提供基本方法与基础指导。%The construction ofgreenway in Pearl River Delta is a prelinlinary practice in china, it provides an important way for improving the urban and rural settlements.The greenway network covers the whole PRD region , yields comprehensive effects and accomplishs the integration of urban and countryside. Basing on the study of greenway network and the summary, of several foreign case studies, this article discusses fully on greenway scale and density.Also, it puts forward a construction evaluation model, in order to establish scientific methods for the next planning stage and make guidance for greenway development.
