摘　　要： 本文利用珠江三角洲1988、1998、2006年三个时相的建设用地解译数据,定量分析建设用地扩展与工业化之间的耦合关系。从珠江三角洲的经验来看,工业化进程越快,建设用地扩展越剧烈;工业化水平与建设用地空间形态变化之间呈现典型的"U"型曲线关系;建设用地的利用效率与它所承载的产业活动的经济效率存在紧密关系,建设用地效率的提高过程与产业结构高级化的演进过程是高度一致的。由此可见,工业化与土地利用两者之间互为因果,相互推动,共同构成"土地—经济"互动系统。必须将用地结构优化与产业升级以及环境再造相结合,才能真正实现土地资源的优化配置。 This paper aims to research on the relationship between construction land expansion and the industrialization of the Pearl River Delta. The Landsat TM images of the Pearl River Delta taken in 1988, 1998 and 2006 are used in this research. The result shows that there are interactions between the stage of industrialization and the intensity of construction land expansion. The relationship between the level of industrialization and the concentration level of the construction land could be represented by U-shaped curve. That is to say, with the improvement of the industrialization level, the construction land tends to disperse first, until the later stage of industrialization, and with the further improvement of the industrialization, the construction land will tend to concentrate. There are also close relationship between the land use efficiency and the industrial efficiency. The process of improvement of land use efficiency and that of evolution of industrial are highly con- sistent. Thus, there are causal link between land use and industrialization. They promote each other and together constitute the ＂land-economic＂ interaction system. In fact, at the beginning of the reform and opening up, the Pearl River Delta had attracted a large number of labor-intensive industries for its abundant land resources and low land price, and had established an export-oriented and extensive industrial development model. At that time, it had been very popular for the local governments to cut down the land price to attract foreign investments. As a result, the industry of the Pear River Delta had developed rapidly at the cost of the rapid consumption of land resources and huge pressure on the environment. With the scarcity of land resources and continue rise of land prices, the constraints of the land resources to the industrial development have increased. With the constraints of land resources and the increasingly stringent land policy, the local governments now have endeavored to propose land use optimization movement counter t
