Systemic research has been done on the mode of compensation for catastrophe risk losses(especially earthquake losses), on the one hand the advanced experience of western countries has been used for reference, on the other hand actual situation of our country has also been considered, and the conclusion is that finance funds should be used according to the principle of insurance, the actual method has been put forward;
anymore, due to the limitation of capital and reinsurance market, commercial insurance companies may still can’t bear the losses of catastrophe even with the help of finance funds, so it’s required to disperse such catastrophe risk in capital market, especially CAT bonds can be used in our country and the mode of emitting CAT bonds also been discussed.
Under this background, the agricultural production imperatively needs a effective risk management tool and institutional arrangement to transfer increasingly huge agricultural risks. Agricultural insurance is a effective risk management tool which transfers catastrophic risks and insure the stability of agricultural production.
We propose a mathematical model for rescue center location with the considerations of emergency occurrence probability, catastrophe diffusion function and rescue function.
Because the catastrophe diffusion and rescue functions are both nonlinear and time-variable, it cannot be solved by common mathematical programming methods.
The possibility of analyzing the processes of the formation and destruction of disperse structures under dynamic conditions was considered using concepts of synergetics and the catastrophe theory.
A considerable disaster is one of disasters of all kinds which is characterized by high tension, highest destruction, and long time between disasters. considerable natural disasters, compared with normal natural disasters, have their own characters. However, the happening of them are still controled by natural rules. Preventing and easing considerable disasters is not only a technical problems, but a complex social issue. There has been two disputing methods to prevent and ease disasters, one of which is ba...
Forest fire calamity could be divided into 5 grades:light,moderate,heavy,serious and very serious.The logarithmic value of grade distance was 1.The method for estimating economical loss of forest fire calamity was also made according to some relative information.
Four catastrophic disaster chains consisted of great earthquakes and very big meteorological disaster in the North China and its vicinity since Qing dynasty have been introduced. A possible mechanism forming the disaster chain, index predicting them and strategy reducing disaster have been also explored preliminarily.
