The measurement shows that the following effects on Chinese economy are brought by large amount of foreign investment： 1） Foreign investment, as an important investment source, boosts the increase of the stock of production factors and improves the supplying potentials of Chinese economy. 2） The application of foreign investment speeds the rapid growth of the total production value and the increases the value of Chinese industry. 3） Foreign investment changes the employment structure of Chinese labor force. 4） The tax in China, to some extent, owes its growth to the adoption of foreign investment.展开更多
On the basis of the census in four seasons from 1997 to 2000 in the East China Sea （23°30＇-33°N, 118°0＇-128°E）, the horizontal distribution of pteropods, the seasonal variations of their abunda...On the basis of the census in four seasons from 1997 to 2000 in the East China Sea （23°30＇-33°N, 118°0＇-128°E）, the horizontal distribution of pteropods, the seasonal variations of their abundance and dynamic mechanisms of these variations were approached with quantitative and qualitative methods. Results showed that the total abundance of pteropods varied clearly with the seasons in an order of decrease of autumn （108×10-2 ind./m^3）, summer （33×10^-2 ind./m^3）, winter（28×10^-2 ind./m^3） and spring （10×10^-2 ind./m^3）. Pteropods were not observed in the north nearshore of the East China Sea （29°30＇-33°N, 122°30＇-125°E）in winter and spring. In all seasons, the peteropod abundance was higher in the south than that in the north and higher in the offshore than that in the nearshore. The major species influencing the peteropod abundance were Creseis acicula in spring, Creseis virgula in summer, Desmopterus papilio in autumn and Limaeina trochiforrnis in winter. The variation of pteropod abundance showed a prominent linear correlation with the surface water temperature and 10 m water temperature, but no significant correlation with both the bottom water temperature and salinity. In summer, the high-abundance distribution area of pteropods was located in the place where the Taiwan Warm Current branched from the Kuroshio. Inautumn, thedistribution area with anabundance higher than 250×10^-2ind/m^3expanded northward along with the Taiwan Warm Current within the mixing area where the Changjiang freshwater, the Fujian-Zhejiang coastal water and the Huanghai Sea Cold Water met together. Water temperature and warm currents were the most important environmental factors that influenced the changes ofpteropod abundance in the East China Sea.展开更多
