基于模糊综合评价的大城市边缘区地域特征属性的界定

为科学制定加快大城市边缘区有序协调发展的途径和策略，提出了大城市边缘区地域特征属性的概念。从人口、用地、经济和社会等方面构建了地域特征属性界定的指标体系，利用模糊综合评价法构建了地域特征属性的界定模型。对北京城市边缘区内的小汤山镇、潭柘寺镇、温泉镇和万柳地区的地域特征属性进行了界定，结果表明：小汤山镇的地域特征属性值为0．4210，具有城市外边缘区的特征；潭柘寺镇的为0．0758。具有乡村腹地的特征；温泉镇为0．4922，具有城市内边缘区的特征；万柳地区为0．7116，具有城市内边缘区的特征。界定结果与实际情况相符。所提出的基于模糊综合评价的大城市边缘区地域特征属性的界定方法是可行、有效的。

Determination of zone feature in fringe of a big city based on fuzzy overall evaluation

In this paper, a conception of zone feature was put forward. A set of index system about how to appraise the attribute of a geographical unit in the urban fringe was formed comprehensively and systematically and it was composed of fifteen indexes in four aspects, namely, population, economy, society and earth utilization. An appraisal model was built up through the hiberarchy analytical method and the fuzzy appraisal method. Taking Beijing urban fringe as example of this study, the attribute of the four geographical units was appraised, they are the towns of Xiaotangshan, Wenquan, Tanzhesi and Wanliu. The featured attribute values of Xiaotangshan, Wenquan, Tanzhesi and Wanliu are 0.4210, 0.4922, 0.0758 and 0.7116 respectively. The above estimations indicate that Xiaotangshan and Wenquan have the attributes of an outer-fringe of a big city, Wanliu district has the attribute of an inner-fringe of a big city, Tanzhesi the attribute of a rural hinterland, which all are coincident to their real actualities of the geographical units in Beijing. The result shows that this method is feasible and effective.
