【摘要】：开发区在促进区域经济发展、城市化水平、城市建设过程中起着重要作用,但是,由于开发区内部产业结构的差异、区位因素不同,导致开发区内部土地的非集约化甚至浪费。根据保定市开发区的区位条件,将其划分为中心区、实验区、东区、西区,从土地利用状况、土地利用市场化程度、土地利用效率和管理绩效4个准则层选取了15项指标因素,运用熵权-TOPSIS模型分析了研究区内土地整体集约水平和内部空间差异性。研究结果表明:保定市开发区土地集约化水平整体较高,但空间差异性显著,中心区、实验区、东区、西区集约化程度依次递减。产业结构的趋同和土地资源的优化配制不合理是导致开发区内部集约化程度不同的主要因素。
[Abstract]:Development zones play an important role in promoting regional economic development, urbanization level and urban construction. However, due to the differences of industrial structure within the development zones, location factors are different. According to the location conditions of Baoding development zone, it can be divided into central district, experimental area, eastern area, west area, from the land use status, land use marketization degree. Land use efficiency and management performance of the four criteria selected 15 factors. Based on the entropy weight TOPSIS model, the paper analyzes the whole land intensive level and the internal spatial difference in the study area. The research results show that the land intensive level of Baoding City Development Zone is relatively high as a whole. But the space difference is remarkable, the center area, the experimental area, the east side. The convergence of industrial structure and the unreasonable allocation of land resources are the main factors leading to the different degree of intensive development zone.
