%X City-land use change(CLUC)in confusion during speedup urbanization is a common problem in many countries and also one of the best concerns of researchers.Correlative studies on it have signality in understanding mechanisms of CLUC and instituting policies of city-land use regulation.The author selected the Zhujiang River Delta in Guangdong,China,one of the regions with the highest level and the most rapid urbanization process as a case.Relations be-tween CLUC and urbanization of its courses,current status and special structure were discussed in this paper.And CLUC characters and trends under different levels,status and special struc-tures of urbanization also were analyzed.The paper first abstracted city-land use information from RS data of1990and2000in Zhujiang River Delta,and then revealed expansion characters and spatial disparities of city-land use.Also,by calculating synthesized index of CLUC(Ulc),28counties in investigated area were divided into3classes of CLUC:high expansion,low expan-sion and comparative stabilization.Meanwhile,the coupling relationship between CLUC and ur-banization was studied by comparing with relative urbanization levels of development.And cou-pling relationship in spatial structure between CLUC and urbanization was further dealt with.The main conclusions show the coupling relationship between CLUC and urbanization is quite good in Zhujiang River Delta from1990-2000.High expansion regions are centralized in the triangle with Guangzhou-Shenzhen-Zhuhai as its vertexes and in both sides along the main traffic lines.The trends of diminishing intension of CLUC are also showed from the cores centered around Guangzhou,Shenzhen and Zhuhai to the marginal areas.
