Therefore, how to establish a rigorous appraisal index system scientifically has been the focus of many scholars during the study of eco-city. However, nearly all the researches are just paying attention to developing some national unified and static appraisal criteria during the construct process of eco-city appraisal index system, without considering regional, dynamic and complicated state. Consequently, it leads to a lot of problems, such as the deficiency of flexibility, insufficient basis for standard-setting, lack of expansibility and contacting between the indicators. Against to these problems, this paper has divided the constructing eco-cities into series types in China from three aspects: regional ecological background, urban evolutionary phase, and urban synthesis condition, with the methods of expert-consulting, analytic hierarchy process, correlation analysis, information entropy, clustering analysis and urban synthesis condition. Meanwhile,this paper presents a new method, the combined dynamic appraisal method, for building the eco-city appraisal index system. Based on the similarity within the same type, this method could construct the combined dynamic appraisal index system more flexibility and more fit to the actual situation of each city. In this index system, the cities within the same dimension and type has been taken as the sample set, and the maximum value, average value and minimum value has been taken as the important references for the determining of each indicators' standard value. Finally, this paper carries on the case analysis for discussing the strengths and weaknesses of this method with the examples of Yibin, Suzhou and Baotou. The research results show that, compared with the present appraisal method, this new method has many advantages. (1) Rationality. The determining of each indicators' standard value are based on the consideration of the value range of the cities within the same dimension and type, so it is more reasonable than just use the actual values of some international metropolis around the globe. (2) Dynamic. After the establishment of eco-city classification database, the standard value of each indicator could be easily refined based on the update of each city's actual value in the sample set. In this way, the real-time and dynamic of this appraisal index system could be enhanced. (3) Flexibility. With this method, we could establish the appraisal index system of various cities more flexible according to the combination of different dimensions and city types. (4) Expansibility. With this method, we could add some new indicators more easily according to the specific characteristics of different cities. (5) Integrity. This method has taken the connection and integrity between indicators into more consideration during the choose process of each indicator. Nevertheless, it also has some disadvantages, such as high demand of data quality, being improved precision, and management difficulties. As the accumulation of eco-city construction data materials and the improvement of management system in China, the new method will provide a better way for the construction of eco-city appraisal index system. 参考文献 相似文献 引证文献
