"The Four Groups Model" on Ecological Space Control of Urban Agglomerations in Chinese
从诊断城市生态系统状况出发，提出通过培育共同价值体系、调查评估生态资源、构建区域生态网络格局和基本生态控制线，并基于生态尺度理论优化城市群生态空间结构，探索了生态需求三角化、生态系统分类、生态功能分区和生态用地分级的四组模型，以保障城市群生态空间数量并提升生态系统质量。
This paper from the perspective of diagnosis of the urban ecological system situation,according to the technology path of cultivating the common value system,surveying and evaluating ecological resource,formulating regional ecological network pattern and the basic ecological control lines,points out the main points of urban agglomeration ecological network pattern.Based on the theory of ecologicals scale,optimize the structure of ecological space in regional urban agglomeration: reserve and key ecological function unit,ecological corridor,ecological conservation areas,town built up area green space.Puts forward the path,to demarcate piece from demand-to decide types under pieces-to plot out sectionon types-to make grades by sectionon,of planning controls.Explore the four groups model,ecological demand triangulating,ecological system classification,ecological function regions and ecological land grading the ecological space control,of urban agglomerations in Chinese.The model can help guarantee urban agglomeration ecological space quantity,improve the quality of urban agglomeration ecosystem.
