| Abstract: | On the basis of the PIB model the theory of gas molecule kinetics,a dif-ferential equation for the population of space debris in low earth orbit(LEO)is established and by using the staistics data and initial conditions given in foreign references,the short-term and long-term evolutions of space debris envionment are analysed. |
