    The level of urbanization in Guangdong,analogous to that of the whole country in terms of development stage,is still low.The regional difference in urbanization is remarkable,cities and towns develop inequally.This paper analysed the influence of economic development,employment structure of labour force,capacity of cities and towns absorbing labour force population density,land resources and some othes factors upon the urbanization process in Guangdong.By using the analysis of time-series tendency,cause-effect and the conversion of surplus rural labour force,the level of urbanization of the province are predicted to go up to 38 percent by the year 2000.

    CALCULATION OF THE MEAN DAILY DISCHARGE THROUGH THE SIXIANJIAO WATERWAY IN LOW-WATER SEASON

    Connecting the Xijiang and the Beijiang Rivers,the Sixianjiao is an important water;uay,through which the flow affects directly those in the downstream reaches of the two rivers,esp.in low-water season.Based on the gauged data and correlation analysis,a mathematical modle,which is simple and practical,was developed to calculate the mean daily discharge through the Sixianjiao waterway in low-water season.By using the modle with the data of the mean daily discharge at Shijiao,Shigou and Gaoyao ganges' cross sections in a certain day,the mean daily discharge of next day through the Sixianjiao waterway can then be calculated.Test computation results show that the modle is quite satisfying.

    The neotectonic movement of Hainan Island has been being rather active since the late Tertiary period.On the basis of the old geological structures,the movement greatly affects the modern landform and the quaternary sediment in Hainan.The characteristics of the movement are as follows:(1)Three groups of main faults,the east-west,north-west and north-east ones,dominate the whole island and form a series of faultblock and neotectonic zones.There are relatively thicker stratum of pliacene series and the Quaternary system deposit in the downwarping area,and in upwarping area the bedrock appears or only thin sedimentary stratum of the Quaternary are on it.(2)The volcanos frequently erupted along the three groups of faults or at the crossford of the faults.The eruptions are of periodic,continual,intermittent and transferable.(3)The earthquakes,closely related to the geological structures,are active and strong,especially in the North and East of the island.(4)The movement of the coast is obviously different in different parts where the East coast is uplifting while the West one is subsiding and the mountains in the middle of the island is mainly rising slowly and intermittently.(5)The modern river valleys mostly develop along the faults.
