摘要
近20年来,我国各类型国家级开发区在数量和质量上都有了很大的提升。对开发区土地利用的质与量进行及时地监测与评价,对于正确引导开发区的良性发展具有重要意义。本文旨在依据国家级开发区土地利用监测和评价的需要,构建了开发区土地利用评价指标体系。在此基础上提出基于标准差系数权数法的综合评价模型,从土地利用程度、土地利用结构和土地利用效益三方面对开发区土地利用进行综合评价。文中案例研究表明:该评价方法简单易行,能科学地反映出开发区土地利用的现实状况,具有理论意义和实用价值。
The use of an index system is an important approach for land use monitoring and evaluation. In order to meet the requirement of land use evaluation in the national development zones, a new index system was proposed, which consists of three perspectives： land use degree, structure and efficiency. Based on the index system, a comprehensive evaluation model was built by using standard deviation coefficient to determine the weights of the evaluation indices. The index system and the evaluation model were tested in the land use evaluation for 10 national economic and technological development zones, and a quantitative score was drawn for comprehensive evaluation in each zone. The results show that the approach is effective and exercisable.
