| 摘 要： | 城市土壤是近年来多学科交叉研究的热点问题．首先对城市土壤概念进行了科学界定以及外延拓展．以不同时期城市土壤研究的特点为依据，将其研究历史划分为萌芽阶段（20世纪70年代之前）、起步阶~3L（20世纪70年代至90年代中期）和快速发展阶段（20世纪90年代中后期以来）．

| Abstract: | Urban soil has become one of the focus of multidisciplinary intersection.This paper scientifically definites urban soil,then,extends urban soil from its essence.According to the research features of urban soil in different periods,the paper divides the history of the research of urban soil into three stages:firstly,the embryonic stage-before 1970s,secondly,the starting stage-from 1970s to mid-1990s,and thirdly,the fast development stage-since mid-1990s. |
