基于PSR框架的城市土地集约利用评价研究——以陕西省为例

Urban Land Intensive Use Based on the PSR Model——A Case Study of Shanxi Province

将"压力—状态—响应(Pressure-State-Response,PSR)"框架引入到城市土地集约利用评价中,能较好地揭示土地利用中人地相互作用的链式关系。文章据此构建了相应的评价指标体系,综合应用主成分分析方法,对陕西省土地集约利用情况进行了测度和评价。研究结果表明:①陕西省城市土地集约利用状况呈梯度分布;②陕西省各城市土地集约利用程度区域差异显著;③PSR系统的协调度与陕西省城市土地集约利用水平成较高正相关,充分反映城市土地集约利用的均衡度,同时模型可信度也比较高。最后提出结论和建议。

From the intensive use of urban land in the relationship between people and land on the effectiveness of the impact of starting the ＂ Pressure - State - Response, PSR＂ into the framework of urban land, it is defined the connotation of the intensive use of land, it can better reveal the interaction of land use in the chain of human relations. Integrated application of principal component analysis and construction the corresponding evaluation index system, this article measures and evaluates the intensive use of land in Shanxi province from the perspective of the region of space. The results show that ： ①the situation of intensive use of urban land in Shaanxi province presents the gradient distribution; ②the degree of land use in cities of Shanxi province presents regional significant differences; ③ urban land intensive is positive correlation with the harmonious degree of PSR which indicates the model is reasonable. Furthermore, it gives us some adviees from research result.
