基于灰区间数决策的城市土地集约利用评价

Based on Grey Interval Numbers Decision of Intensive Use of Urban Land Evaluation

城市土地集约利用评判是典型的区间数多属性决策问题,将基于灰色系统理论的多指标灰区间数关联决策模型应用于城市土地利用状况评价领域,通过引入灰区间数序列的范数完成多指标区间数决策矩阵的规范化处理,建立了多指标区间数整体逼近决策方法,使城市土地集约利用评判方法更加客观.最后通过扬州市城市土地利用状况为实例验证模型的有效性和实用性,为城市土地集约利用评价提供了一种新方法.

urban land intensive use evaluation is typical of interval number multiple at- tribute decision making problems, and will be based on the grey system theory of grey interval Numbers decision index associated model for urban land use status evaluation area, through the introduction of grey interval number sequence of norm many index finished interval Numbers decision matrix of standardized treatment, established the index interval Numbers decision method is the overall approach, urban land intensive use evaluation method to be more objective. At last, by yangzhou city land use status for an example to verify the validity of the model and practical, intensive use of urban land evaluation to provide a new method.
