摘要
本研究以深圳市作为典型城市化地区代表,以直链烷基苯(LABs)作为环境分子标志物,在分析土壤LABs空间分布特征基础上,通过土壤LABs污染水平与城市化过程指标的相关分析,对直链烷基苯指示城市化过程可能性开展初步研究.结果表明,城市化过程中人口规模、用水状况、城市建设、收入与消费及产业结构这5个方面的因素与土壤中LABs污染水平均有相关性,表明环境LABs水平与城市化过程相关,可以作为环境分子标志物用于指示城市化过程.
In this study,we selected Shenzhen City as a typical region of urbanization and took Linear alkylbenzenes（LABs） as an environmental molecular marker to investigate the relationship between soil LABs levels and urbanization indexes on the basis of analysis of spatial distribution of LABs in surface soil.Our results indicated relations between the LABs levels in soil and the five urbanization indexes,such as the population,water supply,urban construction,income and expenditure,as well as industrial structure.These results suggested that LABs levels were correlated with urbanization and could be used as an environmental molecular indicator for the process of urbanization.
