The down-faulted basin zone and high disaster risk zone in Shanxi Province, China

Shanxi Province is a region with frequent occurrence of earthquakes, floods and waterlogging, meteorological and geologic hazards, and agrobiohazards in China. The study shows that the formation and development of the down-faulted basin zone in Shanxi Province provides an available condition for preparation and occurrence of these hazards, so that the basin zone becomes an area with frequent occurrence of the hazards, such as earthquakes, floods and waterlogging, meteorological and geologic hazards and agrobiohazards in Shanxi and with their most serious interaction and mutual intensification. Moreover, the basin zone is an area with dense population and most concentrated industrial and agricultural productions and social-economic property in Shanxi. The comprehensive effect of the two factors caused the zone to be a high natural disaster risk area in Shanxi. For reduction of natural disasters and ensuring the sustainable social-economic development in Shanxi, it is necessary to regard the basin zone as an important area for disaster reduction in Shanxi and to carry out integrated disaster reduction.

THE INDUSTRIAL STRUCTURE AND DISTRIBUTION OF THE BOHAI-YELLOW SEA RIMLAND OF CHINA IN THE 1990S

The Bohai-Yellow Sea Rimland (BYSR) is situated along the coast of theBohai Sea and the Yellow Sea in the northeast of China, covering Liaoning, Hebei, and Shandong provinces, and Tianjin and Beijing municipalities. It has a land area of 491,000 square kilometers, 5.1 percent of the country’s total, and a population of 196 million, 17.9 percent of the total. Theregion is not only the political and cultural center, but also the most important economic center in North China. This paper analyses current status and major problems of industrial structure and distribution of BYSR. According to the national plan, the main goal in the coming decade is: by constantly improving economic structure, economic quality and efficiency, to double the gross national product(GNP), and to raise living standards to a satisfactory level. To realize this goal, agriculture, energy, transportation, some important raw material of industries, and infrastructure should be strengthened, and the engineering industry be improved to

ANALYSIS OF LAND BRIDGE TRANSPORTATION

Land bridge transportation means transportation from one seaport to another by railway across continents instead of by ocean ship. At present, there are two common routes for using land bridge transportation in the world. One is Asia-America-Europe land bridge, the other is Europe-Asia land bridge.Eurasia land bridge has obvious advantages over Asia-America-Europe land bridge due to its shorter distance, shorter transportation time and special freight rate. China started Eurasia land bridge transportation business in 1980. It mainly used the mode of railway-railway combined transportation. The comparison between using Eurasia land bridge and using shipping transportation from China to Northern and Western Europe shows that Euraria land bridge transportation can save time and get foreign exchange in time, and commodity turnover will be speeded up. According to the port layout and railway network structure, China’s land bridge transportation projects are proposed. They are Suifenhe project, Dalian

Comparison Study of Paleovegetation and Paleoclimate in South and North Kunlun Mountains in Pliocene

According to the data of pollen analysis,the vegetation varied greatly between the southand the north of the Kurdun Mountains during the Pliocene.To the south of the Kunlun Mountains,includ-ing their south flank,there was distribution of needle and broad-leaf mixed forest that contained tropical andsubtropical compositions,while to the north of the Kunlun Mountains,including their north flank,therewas distribution of temperate deciduous broad-leaf forest and steppe.In both areas mentioned above,therewere scattered middle Asian arid plants of a lush growth in the late Pliocene.In the Pliocene,the Pamir-Kunlun Ranges acted as the division line of the southern and northern types of plants.Then,with the risingof these mountains,inciuding Pamir,Kunlun and Himalaya,this division line had been moving,until itreached the Xindukushi-Himalaya Mountains at present.

On Mandatory Plans

describes mandatory planning as an important form of planning and management which is determined by the public ownership of the means of production. In a socialist economy owned by the whole people, ownership rights can be neither completely identified with nor completely separated from use rights. Mandatory plans for key enterprises and for major products vital to the national economy provide the conditions necessary to guarantee that guidance plans are effectively implemented and that market regulation serves the socialist economy. Mandatory planning within fixed limits not only does not exclude socialist commodity production but rather conforms to the socialist commodity-money relationship established on the basis of public ownership. The law of value operates through mandatory plans, guidance plans and market regulation. The only difference is the manner and degree to which it is used. Whether the initiative of enterprises will be dampened or arbitrary and impracticable directions will be encouraged by mandatory planning depends on whether the plan accords with the facts and its management is rational. Future mandatory plans must be limited in scope to what is possible and adopt a formulation process which integrates higher and lower levels. At the same time they must recognize the necessary rights and interests of enterprises and also pay attention to giving full play to the role of economic levers. Appropriate decentralization is necessary. However, the state’s direct management of the economy must also be improved and the democratization of national economic policy making must be promoted.

Molecular cloning, identification and characteristics of NYD-SP9:Gene coding protein kinase presumably involved in spermatogenesis

Using cDNA microarray hybridization from a human testicular cDNA library, one gene exhibiting ten-fold difference at expression level between adult and embryo human testes was cloned and named NYD-SP9, which was believed to be involved in spermatogenesis. Southern blot hybridization results showed that NYD-SP9 expressed highly in testis but low in ovary. Protein motif analysis of this cDNA sequence revealed a cluster of phosphorylation sites, indicating its potential involvement in signal pathways during spermatogenesis. Furthermore, one transmembrane helix was predicted in N-terminal region, indicating that putative NYD-SP6 may be served as a transmembrane protein. The proximity of these potential phosphorylation sites to each other indicates that there may be interaction among these sites to regulate spermatogenesis. These findings suggested that protein kinase NYD-SP9 might play a role in male germ cell differentiation.
