    Water resource of the south coastal area in Guangxi have been preliminarily studied in this paper. Being about 50% of annual water amounts, the water amounts in summer have its largest values. The distribution of water resources. declines from east to west. At the Fangcheng city in Western Guangxi, the mean annual rainfall and the runoff depth amounts to 3000 mm and 2000 mm respectively, while the rainfall per squar kilometre is 2×106m3. It is one of theabundant water resources zone in China. Being rich in amount and fne in quality, the surface water resource of coastal zone in South Guangxi have been not fully used at present, therefore, it is bright prospects to exploit the water resource for productive activity. Ones have ever calculated that the supply of water resource is also adequate in the end of 20th century.

    The economic development of Guangzhou in 1990's will face the following challenges:first, the perfected technique will dominate the world economic; second, the Zhujiang Delta will become industry assembly district;third, the South China Sea Oilfield will enter the development stage; last, urban land market will be opened limitedly. These four eiemeuts crake the traditional industry of Guangzhou move away from the urban central district.

    This article points out the characteristics of Karst landform within Shaoguan city,namely, high toposraphy, staircase form landscape, complex geomorphic types, poor vegetation, lack of ground and surface water, and distribution of subsurface rivers. Therefore, what should be done in case developing and utilizing it is to give priority to aliorestation, to develop dry farming, to mine minerals and rocks and to make the full use of its uniqueness of the landscape to develop tourism. This is the relitively rational way to develop and utilize the Karst mountainous area, and it gets access to producing the effect.

    The Cenozoic volcanic rock covers an area of 4159 km2 in north Hainan, consisting 12.3% of the total area of the island. Belonging to tectonics of the rift valley type,the north Hainan is one of the most active Cenozoic volcanic areas in China. Volcanic geomorphy is well developed as a result of long-time and intensive volcanic activities.

    This paper deals with the Quaternary stratigraphy of Hainan Island by means of the C14 dating, K-Ar age method, thermoluminescent method, paleomagnetic method, stratigraphic correlation, sedimentary facies and sedimentary cycles, as well as climatic periods reflected by spore-pollen analysis.

    The outline and the strike of the recent coastline in Ilainan Island have a close relationship with the geologic structure. The origin and development of recent coastal landforms was effected deeply by the rise of sea level since post-glacial period. Besides, the factors of the dynamics, sediment and regional geology also controied the development of recent coastal landforms as it should be.

    Since the special economic zones have been built for more than six years in China, the correct conelusion about the reasonable developing scale of the SEZ should be gained. It is proved that massivity in developmental scale and adventure in developmental speed are unsuitable. These matters lead to that the capital construction investment goes out control, thus bringing about a series of problem, namely, the trouble in financial position, deficiency in material supply, as well as the difficulty of management. If the scale of SEZ is too large, the fulfilment of preferential policies will be curtailed and the specific characteristics of the SEZ will be weakened.The administrative experience of SEZ tells us that the key of running SEZ well (iocs not depend on how large the scale of the SEZ is but how to retain and enhance the characteristics of the SEZ. We should create an investment climate which is comparable to that abroad for foreign investors, and should choose a suitable area in the city of the SEZ where all the foreign funded enterpries. joint venture enterpries as well as cooperative enterpries will be allowed to run business activities which are legal in capitalist society. Thereby, the SEZ of our country will can compete with any kinds of exportprocessing free zone in the world on the basis of equality. The forementioned specific area may be labeled "specific area in SEZ", is one of the models of SEZ that should be chosen nowadays in China.

    Liu and Jordan's formulae (Liu and Jordan, 1962) are revised to estimate the global rediation on inclined surfaces with azimuth from-180° to +180° in Shenzhen. The method for determination of the sunrise and sunset hour angles and the sunshine duration on sloping surfaces in low latitudes is discussed. From the data of direct, diffuse and global radiation on the horizontal surface in the city, the values of Rb and R for each month are calculated, where Rb and R are the ratioes of the average direct and global radiation, respectively, on the tilted surfaces to that on a horizontal surface. It is shown that in some periods of the year, the surfaces toward south, southeast and southwest, within a certain slope range, can obtain more global radiation than the horizontal surface. The annual global radiation on a southward slope of 19° reaches a maximum,3.4% more than that on a horizontal. Since Shenzhen is situated south to the Tropic of cancer, in about 15 days before and after the Summer Solstice, the global radiation on a northward inclined surface is more than that on a southward one at same slope. The annual course of global radiation on a tilted surface differs from that on a horizontal and varies with slope and azimuth.
