城市生态基础设施评价指标体系构建及应用 ——以贵州省六盘水市为例

从城市生态基础设施概念和内涵出发，以自然基础设施和人工基础设施为子系统，基于大气、绿地、湿地、交通运输、能源补给、给水排水、电信通讯、环境卫生和安全防灾9个系统共33个指标构建评价体系，运用均方差法计算各评价指标的权重，采用灰色关联理论建立评价模型，并对六盘水市的城市生态基础设施现状进行评价。结果表明：六盘水市城市生态基础设施属于极差、差、中、良和优等级的综合关联度值分别为0.678 8、0.750 4、0.724 3、0.611 0和0.523 5，说明六盘水市城市生态基础设施属于“差”的等级。其中，自然基础设施属于“中”的等级，与“中”的关联度值为0.828 5；人工基础设施属于“差”的等级，与“差”的关联度值为0.791 2。

Construction and Application of the Evaluation Index System of Urban Ecological Infrastructure

With the concept and connotation of urban ecological infrastructure, this paper establishes an index system for evaluation of urban ecological infrastructure. The paper uses the mean square error method to calculate the weight of each index and the gray correlation theory to construct an evaluation index system consisting of two subsystems, i.e. natural and aritificial ecological infrastructure. The index system includes 9 factors and 33 indicators. The 9 factors are atmosphere, green space, wetland, transportation, energy supply, water supply and drainage, telecommunications, environmental health, and safety of disaster prevention. With the index system a case study was made in Liupanshui City, Guizhou Province. The evaluation results are as follows: the comprehensive index values of the poorest, poor, medium, good and superior infrastructure are 0.678 8, 0.750 4, 0.724 3, 0.611 0 and 0.523 5, respectively. That shows that as a whole the ecological infrastructure in Liupanshui City is of poor grade, in which the natural ecological infrastructure is of medium grade with an index value of 0.828 5, and the aritificial ecological infrastructure is of poor grade with an index value of 0.791 2. Through the evaluation and analysis, we can have a basic understanding of the current situation of the ecological infrastructure in Liupanshui City and the results can be for scientific reference of the programming and construction of Liupanshui City. Also the index system can be applied to others cities.
