【摘要】 目前的土地集约利用评价指标多集中于土地利用的现存状态,较少考虑到人地关系对用地效益的影响。而"压力—状态—响应(Pressure-State-Response,PSR)"框架很好地揭示出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GIS和主成分分析的方法,从区域空间的角度对浙江省11个地级市的城市土地集约利用情况进行了测度和评价。研究结果表明:①浙东北部地区为城市土地集约利用区;②由于区位优势和产业结构差异的影响,浙江省城市土地集约利用状况呈梯度分布;③PSR系统的协调度与浙江省城市土地集约利用水平成高度正相关,充分说明PSR各子系统及其内部各因子之间的协调性很大程度上可以反映城市土地集约利用的均衡度,模型可信度比较高。最后结合研究结论提出了部分政策建议。更多还原

【Abstract】 Current researches rarely discuss the man-land relationship in the course of urban land intensive use,so this paper explains the system of PSR conception and puts forward the index system based on PSR model.Then method of principal component analysis is adopted to calculate the urban land intensive use of 11 cities in Zhejiang province with the formation of the index system and the result is graded.Based on the facts of Zhejiang province,three important conclusions are drawn.Firstly,urban intensive use in the northeastern Zhejiang province is more intensive than that in the southern and western part of Zhejiang province.Secondly,because of the difference of location and industrial structure among these areas,urban land intensive use is distributed as ladder in the spatial of Zhejiang province.Thirdly,urban land intensive is positive correlation with the harmonious degree of PSR which indicates the model is reasonable.Further more,research result gives us some apocalypse.更多还原
