【摘要】 利用全局主成分分析法测度了2000—2016年广东省21个地级市土地集约利用水平,并通过探索性空间数据分析,从全局和局部两个维度,分析广东省土地集约利用水平空间演变特征与差异。研究表明:研究期间广东省土地集约利用水平呈稳步上升态势;区域层面,集约水平平均值:珠三角>粤东>粤北>粤西,珠三角地区集约水平一直高于全省平均值,并拉大与其他3个地区的差距;市域层面,珠三角城市集约水平变化不尽相同,粤东粤西部分城市长期处于低集约水平。从全局看,大多数年份具有全局空间集聚现象,集聚性趋于增强;从局部看,局部空间集聚性和异质性并存,HH型城市分布在珠三角地区,由珠江口西岸转移到东岸;LL型城市分布在广东东部和西部,并且有扩散的趋势。HL型城市布局分散,LH型城市围绕珠三角高集约水平城市分布,两种类型的城市都有减少趋势。更多还原

【Abstract】 Based on the method of global principal component analysis,this paper measured the land intensive utilization of 21 cities in Guangdong province from 2000 to 2016,and analyzed the spatial evolution characteristics and differences of Guangdong’s land intensive utilization from the global and local dimensions supported by exploratory spatial data analysis.The research results were shown as follows:the level of land intensive utilization in Guangdong province increased steadily during the study period;at the regional level,the average degree of land intensive utilization of Pearl River Delta was the highest and always higher than the provincial average degree,eastern Guangdong was the second,northern Guangdong the third and western Guangdong the last.The gap between Pearl River Delta and the other regions was gradually widen;at the municipal level,different cities in Pearl River Delta had different changes in land intensive utilization,and some cities in eastern Guangdong and western Guangdong had long been at a low intensive degree;from a global perspective,most years had seen a global spatial agglomeration in Guangdong,which became more and more obvious over time;from a local perspective,spatial agglomeration and heterogeneity coexisted and HH-type cities were mainly distributed in the Pearl River Delta region,which shifted from the west bank of Pearl River Estuary to the east;LL-type cities were located in eastern and western Guangdong,with a tendency to diffuse toward adjacent cities;HL-type cities were scattered and LH-type cities were distributed around the high-intensive cities in Pearl River Delta,and both types of cities were on the decrease.更多还原
