And TOPSIS method was employed to give comprehensive comparison of water quality of the five lakes. The results indicated that the difference of 14 major water quality indicators was very significant among lakes except copper. In addition,transparency,total nitrogen,total phosphorus had very significant difference among stations for each lake; p H,chemical oxygen demand,oil,total phosphorus,lead,cadmium,mercury had significant or very significant difference among years for each station. The TOPSIS results showed that the fishery water quality of Gaobaoshaobo Lake was the best,and Luoma Lake was just second to it,followed by Hongze Lake,Taihu Lake and Gehu Lake. In combination with the geographic position of each lake,it showed that fishery water quality of the five investigated lakes was basically increasingly better from the south to the north in Jiangsu Province,and the trend revealed high association with the developed industrial economy.展开更多

On the basis of these, static and dynamic models are established to analyze the prevention mechanism for default risk in small amount credit. It is concluded that we must establish a restriction mechanism during operation of small amount credit as long as three values increase, namely, N (potential loss of bad credit record due to farmers' default), Q (probability of successful recovery by small amount credit institution), and S (cost of small amount credit institution punishing farmers after successful recovery). Finally, following countermeasures and suggestions are put forward: perfect laws and regulations and credit reward and punishment mechanism for risk management of small amount credit; bring into play proper function of loan officer in small amount credit practice; widely promote rural "Group Credit Union" system.展开更多
