基于生态文明的西安市经济技术开发区土地集约利用合理度研究

为了全面掌握土地集约利用状况,更准确地对土地集约利用合理程度进行评价,从经济、空间、生态3个方面建立土地集约利用合理度评价指标体系,应用FAHP法确定指标权重,采用模糊综合评价法和综合指数法建立土地集约利用合理度的复合评价模型,对西安经济技术开发区土地集约利用合理度进行定量计算、分析和评价。结果表明,西安经济技术开发区土地集约利用合理度综合分值为78.67,土地集约利用总体上较为合理,经济效益和空间效益集约合理度水平一般,生态效益集约合理度很好。最后根据评价结论提出了有针对性的对策建议。该研究结果可为定量评价土地集约利用合理程度提供参考,为区域土地利用、发展定位、规划决策提供借鉴。

Reasonable Degree of Intensive Land Use in Xi'an Economic and Technological Development Zone Based on Ecological Civilization

In order to understand the situation of intensive land use completely and evaluate the reasonable de-gree of intensive land use correctly, an evaluation indicator system for intensive land use is established from economic, spatial and ecological performances.By applying FAHP method to the calculation of index weights, the compound evaluation model established by fuzzy comprehensive evaluation and comprehensive index evaluation methods is used to assess the situation of intensive land use in the Xi'an economic and tech-nological development zone. Results show that the score for the reasonable degree of intensive land use in thezone is 78.67, indicating that intensive land use in the zone, as a whole, is rational, the reasonable degree of economic and spatial performances is ordinary, and ecological performance is very good.Finally, some sug-gestions are proposed according to the evaluation result. The study may provide reference for the quantitative evaluation of reasonable degree of intensive land use, regional land use and development orientation, as well as planning and decision-making.
