广东城市土地集约利用评价及其时空变异分析

采用层次分析法构建城市土地集约利用评价模利与评价指标体系,对广东21个地级市城市土地集约利用状况进行综合评价.运用Spearman秩相关系数、协调度分析法、聚类及GIS分析法,对评价结果的时空变异规律进行分析.结果表明:(1)在1999-2008年广东大部份城市土地集约利用水平得到不同程度的提高,如东莞、河源等,而阳江、茂名等8个地区则出现下降趋势,江门和汕头下降最为显著.(2)城市土地集约利用综合指数与协凋度相关性不强.进行城市土地集约利用评价时,应综合考虑综合指数与各要素层之间协调度的问题.(3)广东城市土地集约利用水平具有明显的空间分异规律,珠江三角洲地区城市土地集约利用综合指数高于粤北山区及东西两翼.

Evaluation and spatial-temporal variance of urban land intensive use in Guangdong Province

Through constructing an evaluation system of urban land intensive use of Guangdong based on methods of Analytic Hierarchy Process,this paper conducted an overall appraisal on the intensity of urban land use of 21 cities in Guangdong province.The paper gave a spatial-temporal analysis on the appraisal result by applying the methods of Spearman rank relational coefficient,harmonious degree analysis,cluster and GIS analysis.The results showed that:(1)during the ten years from 1999 to 2008,the urban use intensi...
