First, China＇s exports to the USA might continue to decline. Second in the medium term, the higher US inflation rate will lead to a weak dollar, which will negatively affect China＇s exports. Third in the long term, when the US Federal Reserve decreases money supply to control inflation, the US economy might enter another recession, hurting China ＂s exports further. Fourth, China＇s foreign exchange reserve assets might suffer heavy losses when the US inflation rate rises. Conventional foreign exchange investment strategies are insufficient for dealing with these four risks. Investment by China in the major US banks is suggested in the present paper. This strategy would mitigate if not eliminate all four risks. China could gain considerable financial returns on investments with only moderate risk.展开更多

The results show that the seed bank density of abandoned farmland and farmland are more than the others. The seed banks density of the uprightness in abandoned farmland, pond bank I, II and bamboo non-timber forest are downtrend, which is different from the pattern of low-high-low in farmland, and there is no difference among the density of three lays in man-made landscape area. There are 35 families and 102 species totally according to six different land use types of urban wetland in Hangzhou Xixi. A part of its seed bank types obtain the seeds of shrub, which the annual and perennial seeds use the interval of early spring to germinate as the same as farmland type. Farmland type also owns another small part of the seed banks which germinate in Autumn. The seed banks type of bamboo non-timber forest and pond bank are the herbage and shrub type germinating under the condition of drought and interference with the contribution of permanent seed banks.展开更多
