    Considering the fact that in winter the pressure is higher over the land than that over the sea and in summer the pressure gradient is reversed, the intensities of summer monsoon is designated by summing pressure differences between 110°E (land) and 160°E (sea) from 10°N to 50°N at 10 degree latitude interval, in the summing process, only the pressure differences ≤-5mb were included.

    Judging from geodesic, earthquake focal mechanism, earthquakeinduced fissures and quaternary active faults data, we are inclined to think that during the Quaternary period, North and Northeast China were subjected to a NEE-SWW trending compression. The morphotectonic evolution of these regions during this period was closely related to this te-ctonic stress state.1. NE (or NNE) and NW (or NWW) trending conjugate faults were formed or re-activated under the fore-mentioned compressional tectonic stresses. Rivers which crossing the NE (or NNE) trending active faults would be deflected right laterally, while those cro-ssing the NW (or NWW) trending active faults would be deflected left-laterally.2. A series of NE trending late Cenozoic down-faulted basins were formed under the NW-SE tensile stresses.3. The uplifted areas between the down-faulted basins were either simple tilted fault blocks or up-warped areas under NE-SW compressions or just a transverse highland which represented the remnant part under smaller rates of tensional stretching between two adjo-ining basins.4. Many rivers changed their courses or were captured by other rivers as the uplifted or up-warped areas were formed between down-faulted basins.5. Near one end of a transcurrent fault, an uplifted area was often formed on one side of the fault, whereas a depressed area was formed on the other side. Near the other end of that fault the reverse was the case. This was because the different sides of that fault moved in reverse directions.Basing upon the fore-going considerations, the following models of morphotectonic ev-olution related to faulting in North and Northeast China may as follows:1. Down-faulted basins with intervening tilted fault block highlands.2. Down-faulted basins with intervening up-warped highlands.3. Down-faulted basins with remnant highlands in between.4. An alternation of up-warp and down-warp on either side near the two terminus of that transcurrent fault.

    This research studies the mechanism of combination of city districts in urban geogra-phy. Modern cities, particularly the large ones, have developed into large regional compre-hensive agglomerates. It would be difficult to explain urban geographycal characteristics if the urban district structure has not been analysed.

    The four special economic zones so far set up In china Lave varied backgrounds which affect their growth. Three groups of factors are identified for appraising the growth potential of the special economic zones, viz. proximity to an international trading city, kinship con-nections with the overseas Chinese, and factors of production and transportation. The Shen-zhen SEZ seems to be in a most advantageous position because of its proximity to Hong Kong, an important financial centre, the third container port in the world, an industrial city and a huge market. It has good transportation links with Guangzhou and Hong Kong, but its port at Shekou is less than satisfactory for its limited draught. This can only be re-medied by the completion of the deep-water berths at Chiwan. The poor infrastructure of Shenzhen presents another problem, for it is difficult to expand its infrastructure of fast enough to keep pace witr its rapidly growing industry and population. The Zhuhai SEZ is relatively poorly located. Macau, the city next to it, is much less prosperous than Hong Kong. In respect of transportation, it is only connected with Guangzhou by a third class road. It has no deep-water port except a shallow one. It has little infrastructure to support rapid growth. Yet its potential for tourism seems rather promising. Shantou is a city with abundant supply of skilled labour and sound light industrial infrastructure. Quite a num-ber of overseas Chinese now residing in Hong Kong, Macau and particularly Thailand are from this general1 area. The Shantou SEZ thus has been endowed with plentiful supply of production. The only deficiencies are its limited electricity supply and the absence of ra-ilway connections. Xiamen, in many respects similar to Shantou, but its transportation links are far better than Srantou. A deep draught port is under construction and its air-port is to be expanded. It is also well served by rail transport. Indeed, its transport reso-urce is the best among the four Chinese special economic zones. Judging from existing con-ditions and in terms of their potentiality for investment, the four zones are ranked as follows: Shenzhen, Xiamen, Shantou and Zhuhai.

    The locational selection for industries i s one of the core problem in the study of indu-strial geography, because to select a rational or optimum location will bring forth good eco-nomic effectiveness for industrial production and distribution. The present paper discusses the facts that influence the selection of location for light industry,1. The paper analysis a number of factors, such as: raw material, energy resources, comsumption, transportation, water supply and water quality, labour force etc. that influen-cing the Location selection for Light industries. Among these, the raw material is the lea-ding factor because of their weightlessness, effectiveness for a given period of time and diffi-cult to transport. Then according to the extent of their influence, the author based on cer-tain economic technological index classified them into groups.2. The author inquired into the restrictive factors for location option, especially the leading factors. From the point of raw materials and comsumption factors, discussed the reasonable locational orientation. Depending on the previous discussion, the light industry orientation are divided into 1. the industry orientation determined by raw material; 2. the industry orientation determined by comsumption; 3. the industry of mixed orientation.3. Some macroscope factors that condiiioned the locational selection of light indus-try, such as the rational development and utilization of resources, pollution control and en-vironmental protection, economic coordination between regions etc. are discussed too.

    Using aerological data observed twice daily in the period of June-August 1979, the ave-rage zonal and meridional components of total, advective, and eddy transfer of water vapour at six stations surrounding the Huaihe river basin at earth’s surface, 850,700, 500,400, and 300 mb levels are computed. It shows that on the level where the maximum of zonal com-ponent of total transfer occurs higher than that of meridional component, vertically integra-ted transfers of zonal component are all eastward and those of meridional component are all northward. The intensity of the zonal components of the eastern part is stronger than that of the western stations, and the intensity of the meridional component over the southelrn part is stronger than that of the northern station, indicating the zonal divergence and meri-dional convergence.Calculation of water vapour flux divergence shows that there is water vapour sink over the Huaihe river basin in Summer, vertical integrated water vapour flux divergence compu-ted seperately by total transfer and advective transfer and indicates that both has the same Fign but the value of the latter is by 67 percent larger than the former. Therefore, using average data of wind and humidity to calculate water vapour flux convergence may lead to overestimation.The diurnal variation of water vapour transfer is evident, and it is caused mainly by the diurnal variation of wind. There is large difference in the calculating of vertically integ-rated water vapour flux divergence by the data of 0000 and 1200 GMT. Therefore, in ca Iculating water vapour transfer we must use daily average observations data.

    After Liberation, under the State leadetship, and with its energetic support, great achi-evements were made in China’s industrial and agricultural production. However, before 1978, the vegetative covers were being damaged owing to indiscriminate felling of trees, over grazing of grasslands and excessive land reclamation for farming. Furthermore, water and mineral resources were not rationally utilized, nor were the industrial productive forces and transport network rationally distributed All these lead to serious soil erosion in some places, which, in turn, resulted in a rapid drop of the varieties of wild animals and plants, in the reduction of the carrying capacity of pastures, in the aggravated wind erosion, and in the serious environmental pollution in some industrial bases. In short, the irrational exploitation and utilization of natural resources brought about the deterioration of the natural environ-ment.The present article consists of three parts, dealing with the existing problems mentioned above. In Part I, the author points out that, in order to maintain ecological balance and to make the natural environmmnt more suitable for living and production, it is desirable to draw up an overall and comprehensive territorial planning. It is the central task in exploi-ting and harnessing the territory rationally. This part discusses the task, characteristics, con-tents and types of the territorial planning, as well as its regional division. The author holds that the task of the planning are to make a comprehensive survey of the natural, human and economic resources, and to exploit, utilize, control and protect the resources rationally. The planning, therefore, should be regional, comprehensive and strategic in nature.It is also argued about that the territorial planning, is, in fact, the regional planning. This paper explains this point of view wuh examples. There are roughly two types of terri-rorial planning, namely the national and the regional. The latter may refer to those for the province or for the autonomous region.To conclude, the discussion in Parts II and III centers on the assertion that a study of economic regionalization is the foundation to draw up the territorial planning, and the long-term plan of the national economy should be based upon the territorial planning. In a coun-try with a vast territory like China, the regional differentiation is so prominant in physical, social and economic conditions that it is of vital importance to develop regional predomina-nce. The economic development of a region must adapt to the local conditions. Therefore, both the territorial planning and the economic regionalization should be made from a regio-nal, comprehensive and comparative point of view. Of course, all these problems need fur-ther study.
