摘要
基于“压力-状态-响应(Pressure-State-Response,PSR)”模型构建反映土地集约利用程度的指标体系,结合地理信息系统(Geographic Information System,GIS)、空间分析等一些方法,从空间和时间尺度对山东省17地市的土地集约利用程度进行测。研究结果表明:鲁南和半岛地区城市土地集约利用度较高;受区位和产业结构差异的影响山东省城市土地集约利用程度呈现阶梯状分布;十年来山东省城市土地集约利用程度总体上呈上升趋势;PSR系统内部协调度也趋于标准,说明协调度的标准化很大程度上可以促进土地集约利用度的提高。
Based on the"Pressure-State-Response(PSR)"model,this paper constructed an index system reflecting the intensive use of land.Combining Geographic Information Science(GIS),spatial analysis and other methods the intensive use of land in 17 cities in Shandong Province was evaluated from the spatial and temporal scales.The results showed that:The intensive utilization degree of urban land was higher in Lunan and Peninsular regions;The intensive utilization degree of urban land in Shandong province present a ladder distribution under the influence of regional and industrial structure differences;The intensity of urban land use in Shandong Province were on the rise in the past ten years;The coordination degree within the PSR system also tended to the standard.It also showed that the standardization of coordination degree could promote the improvement of land intensive use degree to a large extent.
