基于PSR模型的历史文化名镇风貌保护质量评价——以兰州青城为例

The Evaluation on the Feature Protection Quality of the Historic Towns Based on PSR Model:A Case of Qingcheng in Lanzhou

历史文化名镇风貌保护的质量对于名镇进一步保护与开发具有至关重要的意义。为了更好地衡量风貌保护工作的水平,引入生态学中的PSR评价模型,从风貌压力、风貌状态、风貌响应三个维度建立历史文化名镇风貌保护质量评价指标体系,最后运用模糊综合评价法对兰州青城的风貌保护质量进行评价。研究发现:基于PSR模型构建的历史文化名镇风貌保护评价指标体系在实践中能够准确反映其保护状态和现状问题,具有较高的科学性和可操作性,能够为历史文化名镇风貌保护工作提供指导和参考。

The protection quality of the features of historic towns is of vital significance for the further protection and development of historic towns.In order to better measure the feature protection work,the PSR evaluation model in ecology is introduced to establish the feature protection quality evaluation index system of historic towns from three dimensions of feature pressure,feature status and feature response.Finally,the fuzzy comprehensive evaluation method is used to evaluate the feature protection quality of Lanzhou Qingcheng.It is found that the feature protection quality evaluation index system for historic towns constructed based on PSR model can accurately reflect the protection status and current problems in practice,and is highly scientific and operable,and can provide guidance and reference for the feature protection work of historic towns.
