SPATIAL DIFFERENCE OF URBAN LAND INTENSIVEUSE BASED ON THE GIS AND PSR MODEL——A CASE STUDY OF ZHEJIANG PROVINCE
基于PSR模型构建指标体系,用主成分分析法计算浙江省11个城市土地集约利用水平,发现浙东北高于浙西南,空间上呈阶梯分布,且集约度与PSR协调度正相关。
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.
