对城镇土地集约利用及其增长方式转变进行科学合理评价, 是提升城镇土地整理与管理 水平, 最大限度提高土地集约利用效率, 确保可持续发展的重要手段。按照科学性、可比可量性、 适中性、层次性、公平性和目标导向性等原则, 综合考虑土地集约利用的经济、社会和生态效益, 从转变增长方式的角度, 构建城镇土地集约利用与转变增长方式综合评价指标体系。通过熵技术 支持下的AHP 模型与专家群民主决策支持下定性指标定量转化的赋权方法确定评价指标的权 系数; 采用模糊隶属度函数法对评价指标进行量化处理; 在此基础上, 构建基于指标体系的多目 标多层次模糊综合测度模型计算综合评价指标值。以北京市海淀区北部新区为例进行综合评价 研究, 评价结果显示, 目前北部新区城镇土地集约利用程度较低, 体现在水土资源利用、生态环境 友好等方面指数不高, 今后应进一步转变增长方式, 提高土地集约利用水平。

The synthesis evaluation of intensive land use and growth pattern transformation of towns is very important means for exalting the land - use management level, enhancing the intensive land use efficiency in maximum, and insuring the sustainable development. According to such six principles as scientific、comparable、mezzo、delaminating、impartial and objective - oriented, considering comprehensively economic, social and ecological benefits of intensive land use, this paper constructed the synthesis evaluation index system of intensive land use and growth pattern transformation of towns, from the angle of growth pattern transformation. In order to give the weighted coefficient values of evaluation index, it used the AHP models based on entropy technique as well as methods about transforming qualitative index to quantitative index based on expert opinions; and quantified the positive and subtractive index respectively by means of fuzzy membership functions; then, based on the synthesis evaluation index system, it constructed a multi- layer, multi- objective fuzzy comprehensive evaluation model to assess the synthetical level of intensive land use. At the end, this paper applied this method in the synthesis evaluation of intensive land use and growth pattern transformation of towns in the North New Area of Haidian in Beijing. Results show that, the intensive land use level of towns in the North New Area is low as a whole, and the index of resource utilization and environment amity is lower. So, for the future, we should transform the growth pattern more and improve the level of intensive land use in towns of the North New Area.
