An Empirical Study on Urban Residential Differentiation ——Take Jinxiang Community of Wucun Street in Xiamen for Example [PDF]
, 2009 我国城市居住空间分异现象是伴随着80年代的市场经济体制改革及90年代开始的住房商品化进程逐渐衍生出来的。针对北京、上海、广州等大城市的研究表明，我国城市居住空间分异现象已在多种尺度上出现。本研究以梧村街道金祥社区为例，考察现阶段厦门市的居住空间分异及其分异的程度。对厦门的研究将有助于了解类似于厦门的我国其他中小城市居住空间分异现象的发展状况，从而更好、更全面地把握我国城市居住空间分异现象的总体进程。 本研究在划分不同类型住宅区的基础上，对不同类型住宅区居民的收入、职业、文化程度 ...

Shuitu Baochi Xuebao, 2004 利用地统计学对黑龙江省双城市薄层农田黑土的全碳和速效氮、磷、钾的空间异质性进行了分析,结果表明四者均具有空间异质性。土壤全碳含量的空间异质性最高,主要受黑土层厚度的影响,土壤速效氮磷钾的空间异质性较差,主要受随机因子的影响,占80%以上。全碳和速效氮、磷、钾的空间有效最大相关距离分别为15.7km,4.6km,11.2km,7.1km。土壤全碳与碱解氮存在极显著正相关。
