生态文明价值范式转换下的城市生态空间 绩效研究

秉承"哲学为基础、科学理论为依据、技术为手段"的评价等级体系,在自然内在价值与外在价值共存的生态价值认知范式下,以生态学理论为依据构建以内、外绩效为主体的城市生态空间绩效评价体系和内、外绩效协调度模型,以及绩效发展强度模型,并在GIS技术支撑下实现量化结果的空间化表达。实例证明可得到城市生态空间绩效与协调性的数量结构特征与时空变化特点,可识别高效的生态空间格局、定位低效空间,能从数量分布与空间分布方面更全面地了解城市生态空间的质量,协助判断城市发展的趋势。以期为城市评价工作提供新的视角,为城市生态空间质量的监督、监测提供一种可更新、可视化的时空量化方法。

Urban Ecological Space Performance under the Value Orientation of Ecological Civilization

Adhering to the evaluation hierarchy of "philosophy as the foundation, scientific theory as the basis, and technology as the means", this paper turns to an ecological value cognition paradigm for the coexistence of intrinsic and extrinsic values of nature by taking natural ethics as the philosophical foundation under the value orientation of ecological civilization. The connotation of urban ecological space performance is analyzed with ecological theory as the scientific basis, and the system for evaluating urban ecological space performance is constructed, as well as the internal and external performance coordination model and the performance development intensity model. Furthermore, the spatial representation of quantitative results is achieved with the support of GIS technology. The exemplifications show that the proposed method can obtain the quantitative structural features and spatiotemporal variation characteristics of urban ecological space performance and coordination; can identify the efficient ecological spatial patterns and locate the inefficient spaces; and allows more comprehensive understanding of the quality of urban ecological spaces regarding quantitative and spatial distributions, thereby assisting in the estimation of urban development trends. While providing a new perspective for urban evaluation, this study also offers a renewable and visual method for the quality supervision and monitoring of urban ecological spaces.
