    As we know,good and stable rice yield highly depends on meteorological conditions.Most of the lean years in Guangdong Province were due to meteorological damages in history.This paper discusses several agroclimalic problems which are relative to the rice yield in the Province.The relationship between rice yield fluctuations and meteorological factors is analysed.The tendency of climatic oscillation during the last century is investigated,and the way of making full use of climatic resources to achieve good rice yield is suggested.

    Lufeng county is situated at the eastern coast of Guangdong,facing the fishing ground of the continental shelf in the South China Sea.It is one of the major fishery counties in the province.By 1986,its aquatic product output had been raised to 40.7 thousand tons,accounting for 2.8 percent of the total of the province.In this paper,the author makes use of an Analytic Hierarchy Process,for short "AHP",to research the development strategy of the fishery by the end of this century.The specific development strategies and measures are put forward as:(1)to attach great importance to development strategy of fishery;(2)to control inshore fish catch and improve deepsea fishery;(3)to develop marine cultivation and improve the breeding technique and ecological environment;(4)to develop fresh preservation,processing and comprehensive utilization of aquatic products;(5)to set up marine fishing bases and marine cultivation bases;(6)to improve fishery management.

    Tropical Gaolei region,as the largest tropical area in Guangdong Province,is important production bases of tropical crops,fruits,sugarcane and peanut.Based on the analysis of the main climatic resources and damages,some results are found as follows:(1)The light and heat resources are relatively rich in Gaolei region,especially from May to October.Tropical crops can be cultivated through the winter,though they may be affected by low temperature damage occasionally.(2)The precipitation in wet and in dry seasons differs greatly.During dry seasons the spring drought is generally serious especially in the west Leizhou Peninsula.(3)In the north of the region,there are also a lot of areas suitable for planting tropical crops due to their good local climatic environments.(4)Typhoon affects the region frequently,so that it is necessary to carry out a series of protection measures for agriculture development.

    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.
