基于模型耦合的首都功能核心区水文化遗产价值评估

Value assessment of water cultural heritage in capital functional core area based on coupled model

首都功能核心区水文化遗产是北京城市发展的历史见证,也是北京创建国际一流和谐宜居之都的重要保障。通过梳理首都功能核心区水文化遗产脉络,构建了首都功能核心区水文化遗产价值评估指标体系,采用基于赋权和熵权组合权重的灰色关联度分析方法评估了首都功能核心区主要水文化遗产价值。结果表明:基于赋权和熵权组合权重的灰色关联度分析方法的评估结果相较传统方法准确性高,稳定性强;北护城河、金水河、什刹海、北海和陶然亭水文化遗产价值评估为Ⅰ级,具备较高的社会经济开发价值。

The water cultural heritage of the capital functional core area is a historical witness of Beijing urban development and an important guarantee for Beijing to create an international first-class harmonious and livable city.By sorting out the water cultural heritage of the functional core area of the capital,constructing an index system for evaluating the value of water cultural heritage of the functional core area of the capital,proposing a grey correlation analysis method based on the combination of assignment and entropy weight,and combining with the evaluation index system to scientifically and objectively assess the value of the main water cultural heritage of the functional core area of the capital,in order to promote the management,protection and utilization of water cultural heritage units.It is found that the assessment results of the gray correlation analysis method based on the combination of assignment and entropy weights are highly accurate and stable compared with the traditional method.The value of the water cultural heritage of the Northem Moat,Jinshui River,Shichahai,Beihai and Taoranting is assessed to be Grade I,which has high socio-economic development value.
