%X This paPer researches the urban spatial development on the Two-Lake Plain (in CentralChina)for the past more than 2000 years,and following conclusions are obtained:1.The urban administrative gradation has changed from 2 grade to 4 grade:2 grade during22lBC AD220 and AD589 756;3 grade during AD220 589 and AD757 960;4 grade duringafter AD960.2.The urban development has two historical perids:the period having Jiangling as the chiefcity(before AD1279)and the period having Wuhan as the chief city(after AD1279),and In the13th century,the modern urban spatial structure took its shape basically.3.The urban distributions have 3 times spatial dynamic equilibriums:equilibrium of the distribution of the cities above county level around 200BC,that of cities of county level and above countylevel around AD900,that of all cities and towns around AD1980.4.The centres of gravity of the distributions of cities and towns moved from northwest Qianjiang county to southeast Jianli county,with a straight distance of about 75 kilometers.5.The urban spatial development has a typical circular-convergence model.The shorter thedistance is from the core of the plain,the more the cities which appeared later,almost all citiesabove county level distribute in the periphery of the plain which is the ecotone of hills and plains,showing a powerful ecotone function.6.The urban spatial structure basically accords with Walter Christaller's central-place-theory,having a embryonic compound system of central place stucture which mainly combines the transportation priority with the commerce priority.
