    The Chinese pig breeding has a long history. 9000-6000 years ago, the Chinese ancestors already tamed and trained the local wild boars. The Chinese ancient people paid great attention to the selective work of pigs. So, as early as in the Han Dynasty fine germ-plasm of Chinese pigs was well-known at home and abroad. During the Han Dynasty, the Small-ear pig of South China was introduced into Da chin country (Roman empire)to be bred into the ancient Roman pigs. By the seventeenth and eighteenth centuries, the Chinese pigs(Guangdong pig species) were introduced into Britain, the USA, etc. Then they. played an important role in the improvement of those countries' pig species.In recent years, for lack of good species resource some countries with developed animal husbandry have paid great attention to Chinese pig species and introduced them to many western countries. They have got the encouraging effects. Therefore nowadays France, Britain, Japan,U. S. A. and Netherlands are all carrying out the resources on pigs and hope to make greater contributions to the improvement of the world's pig species.

    Hulunboir is a region very rich in natural resources. However,for a long time because of improper exploitation the rich natural resources have not promoted the efficient industrial development or accelerated. The region's industrialization process,since the start of the reform,there again have emerged some new contradictions in the exploitation of resources.Through our analysis we believe that the following industrial strategy should be adopted in Hulunboir: centering on the exploitation of the native resources, sustainablly developing the depth of resources processing and building up the structure of industrial departments with local characteristics.After having analysed the characteristics of the resources and the present situations and trends of industrial development in Hulunboir, we have reclassified its industrial departments and they are divided into three major types: the key industrial department, the general─supported department and the restricted industrial department. The key industrial department mainly includes the energy industry, the food industry, the beverage industry, the forest products processing industry (including paper─making industry,furniture industry, etc.)and the monferrous matallurgical industry, the general─supported department includes leather, textile, chemical products, mechanics,building materials, garments, medicine, electronics, steel─making, plastics, rubber products and feed─processing industries;the restricted industrial department inclndes some high energy consumption and iron─smelting industries.In conclusion the author suggests that during the industrial development we should natice six issues, including the application of industrial policies,the enhancement of the infrastructure construction and the environmental protection etc.

    NATURAL RESOURCES AND REGIONAL EXPLOITATION IN THE LIAOHE RIVER DELTA
    Xiao Duning
    1994, 9 (1):  43-50.  doi: 10.11849/zrzyxb.1994.01.006
    Abstract ( )   PDF (553KB) ( )   Save
    The Liaohe River Delta is one of the main agricultural bases in Liaoning Province,and the third largest oil field in China. There are aboundant soil resource,aquatic products, and the sceond largest wetland in the world. Oil pumping field,rice fields,reed land and shrimp fielde are the main ways of regional resources exploitation. These have led to many environmental problems and to the changes of landscape ecosystem. So the following aspects must be especially noticed:a. Fully tap the potentialities of resources. The exploitation of agricultural resources must be coherent with that of oil and gas resources underground,The land use must be comprehensively arranged.b. Fresh water is the main limiting factor in intergrated agricultural development in the region. It is very important to modulate water resources by building water engineering ,such as resevoirs,and to use the water─saving measures.c. Conserve the wetland landscape and ecosystem dominated by reed, provide habitats for aquatic creatures and precious water birds, increase. the coverage of green vegetation and improve the primary productivity.d. The protection and breeding of aquatic product resources of the estuary,such as carb(Eriocheir sinensis),should be strenghtened.

    Xizang Autonomous Region (Tibet) is a vast area. There the land suitable for cultivation is few but centralired, the land suitable for pasture is large but different in quality ,and the highfrigid land and the land unsuitable for agriculture are broad. All of these features decide the structure, scale and layout of agriculture in izang. At present the developmental level of lands in Xizang is low, its marketable production is backward and some land has deteriorated so its economic and ecologic benefits are not high, Therefore, alterwards the'intensification of scentific management, incireasing the investment, deep development and protection of thd land resource suitable for agriculture, foresty and pasture reinforced. it is the strategic guiding principles and effective countermeasures for promoting the development of agricultural economy and improving the agricultural productive conditions and ecologic of xizang to raise the per unit area yield of the existing cultivated land improve the grassland, construct the artificial grassland, protect the forests. etc..

    This article discusses deeply the present situation, existing problems and response plans of vegetable production in the contiguous area of Shanxi province, Shaanxi province and Inner Mongolia Autonomous Region. A new energy and heavy chemical industry base is now under construction in the area.After surveying many times and analysing a large amount of data. this article clucidates that the level of vegetable production at present is too low to suit with the needs of the large-scale economic development in the area because of the effect of the natural environment and the backward farming way, According to the results of analyses, it is found that there are three vulnerable points of vegetable production, namely, the off season is too long, the area of protected production is too small and the degree of professional production is greatly lower than that required.In combination with the author's successful experiments on the spot and the practical conditions of the area,this article sugests that the countermeasure of vegetable production in the area should be to develop the vegetable production on the protected fields where the economic benefit is higher. By doing so. the popular vegetable production can be brought about and the reform of farming and planting. can be encouraged. As to the layout principle of vegetable production bases,the opinion is that making the present and planning key cities be the main core market and gathering-alloting places and taking the key cities and major factor factory-mining districts as the chief objects of supply. In regard to the technical line,this article advances the principle that it is important to have stress,batch order and stages in construction policy,It is necessary for the local government to perfect the market control mechanism,to pay attention to and introduce the science and technology forces,to popularize the advanced experiences,etc.

    RESOURCE PHYSICS AND THE ECOLOGICAL COST COEFFICIENT EVALUATION OF RESOURCE CONSUMPTION
    Li Dehu, Li Shunqi
    1994, 9 (1):  85-92.  doi: 10.11849/zrzyxb.1994.01.011
    Abstract ( )   PDF (488KB) ( )   Save
    Resource physics is briefly introduced in this paper. By prolonging resource physics which is based on entropy theory,and introducing the exergy concept, a new idea that natural resources can be measured by exergy is set up. The formula of the ecological cost coefficient of natural resources consumption and the process analysis method are also put forward. By this means resource utilization can be optimized. Finally, an example of the analysis of accumulated exergy in the process of chlor-alkali production is given.
