| 摘 要： | 长江源自然环境严酷，以草原退化、森林萎缩、水土流失、气候暖旱化、冰川退缩、雪灾频繁为代表的生态环境退化正在进行。宜采用保护、恢复和改善林草植被系统来对其进行综合整治。

| Abstract: | A very fast
simulated annealing (VFSA) algorithm is proposed in this paper, on the basis of the
turbulent model established on the generalized Boltzmann-Gibbs statistical theory and
derived from numeral and temperature-dependent pseudo-Cauchy distribution for the purpose
of the improvement of the acceptable probability. The results of the synthetic and actual
data of amplitude versus offset (AVO) inversion show that VFSA can be used to search for
the global optimal target within a large range and at a high temperature, to secure a
stable solution, a strong resistance to random noise, a high precision of inversion, and
especially a fast-speed VFSA convergence. |
