    Based on the investigation of litchi production in Guangzhou and the analysis of its relationship with climate, the author suggests Guangzhou be divided into four climatic regions for litchi production according to fuzzy classification, they are: the North Mountain Region unsuitable for litchi production, the Northern Middle Hill Region subsuitable for middle-maturing and late-maturing litchi, the Southern Middle Hill-Flain Region suitable for middle-maturing and late-maturing litchi, and the South Plain Region suitable for early-maturing litchi. The climatic features and resources, the keys to litchi production in different regions are discussed in detail. Finally, some suggestions about the rational layout of litchi production in Guangzhou are advanced.

    Abstract ( )   PDF (477KB) ( )   Save
    The coastal line of Guangdong Province is more than 6000 km long, about 1/3 of that in China. The coastal area of the province is situated in the tropical and south subtropical zone. In the area there. are about 23,000 ha of the sand vegetations which are sparse and low. The coastal sandy soil there is characterized by its loose granules with poor water and fertilizer holding capacity. The sand vegetations can be divided into two types: from the sea shore to the inland, occurs sandy grassland, and then sandy shrub forest land. For the transformation and utilization of the sand vegetation, suggestions are given as follows: (1)completion of coastal windbreak belt system; (2)plantation of various plot forest on the higher land, which is not suitable for farming; (3)establishment of forestry centre and development of forestry.

    Guangdong Province is very succesful in implementing the policy of opening to the outside world. In the last ten years, the rural enterprises in the province have been rapidly developed, and the development has fostered the process of urbanization. Five roles are summarized as follows: (1)abstracting labour force from rural villages to townships; (2)restructuring the rural economy from a single agricultural one to a diversified one; (3)providing more and more finnacial resources to improve the material conditions and mental outlook in the countrysides; (4)bringing new ways of production and life and new concepts into rural areas; (5)producing more materials for city construction and consumption.

    Abstract ( )   PDF (363KB) ( )   Save
    Specific method and experience of artificial multiplicanon of fishes in the Hejiang River, Guangdong Province, are introduced. Utilization of the method could rapidly improve the resource and production of fishes, and achieve quite good economic returns and ecological benefits. It could also provides us a useful model to develop artificial multiplication of fishes in other rivers.

    THE EVOLUTION OF LAGOON-INLET SYSTEM AND SEDIMENT TRANSPORT IN SHANWEI HARBOUR, GUANGDONG

    1988, 8 (4):  327-335. 
    Abstract ( )   PDF (648KB) ( )   Save
    The development of Shanwei harbour is associated with the development of the lagoon-tidal inlet system where it, is situated, esp. with the growth and decay of the inlet margin spit that was thought a natural breakwater. In past 50 years, the spit changed in trend and conditions. On Aug. 2nd 1979 it was broken during the 8th typhoon. In this paper the relations among the development of the lagoon-inlet system, the growth-decay of the spit and the transport of the sediment are discussed. This is the course of development of Shanwei lagoon-inlet system: (1) open bay stage, (2)semi-close lagoon stage, (3)lagoon-inlet stage, and (4)breach and decay stage. Shanwei harbour has developed in the 4th stage.

    ANALYSIS AND EVALUATION OF THE GEMORPHOLOGICAL CONDITIONS FOR WATER CONSERVANCY CONSTRUCTION IN GUANGZHOU
    Wang Huibin
    1988, 8 (4):  336-344. 
    Abstract ( )   PDF (597KB) ( )   Save
    The relationship the shape of the river basin and floods is analysed by calculating the shape coefficient. The analysis of the main five river systems in Guangzhou shows that their branch proportions are high and close. The geomorphological conditions for storing and channelling water in the area are quite good, but the floods are fairly frequent. According to the geomorphological characteristics, four regions are delimitated and evaluated for water conservancy construction. Relevant engineering measures of water conservancy are also suggested.

    Abstract ( )   PDF (594KB) ( )   Save
    Meteorological data in summers from 1.951 to 1986 are used to analyse the relationship between the appearences of hot days (daily maximum temperature ≥36℃)and their accompanied synoptic situations in Guangzhou. The result shows that typhoon is the major system to cause the hot days, whereas only 13% of hot days are caused by subtropical high. The adiabatic heating effect of the downdraft on the western side of typhoons is the most significant factor causing very high temperature in summer, according to the calculation of vertical motion.

    The distribution of the dry valleys in Yunnan and the characteristics of the vegetation in the valleys are expounded in this paper. According to the annual mean temperature and the accumulated temperature of above 10 C, the dry valleys are classified as warm and hot types, which are further divided into extreme dry, dry and semi-dry valleys on the base of’their annual mean humidity, annual precipitation and the duration of dry period. Five suggestions are finally given to the development and management of the dry valleys in Yunnan Province.

    Three strategies are put forward in this paper for promoting the development of the district. The first is the coordination of soft environment and hard environment. In some case, the improvement of the soft environment should go ahead of that of the hard one. While developing hard environment, the district should enhance its solf environment such as completing laws and ragulations, collecting talented People, reforming management system, lowing down dicision-making power and raising work efficency. The renewal of traditional concepts, the education of job and social morals are also very important.
