Abstract: The land salinization and desertization and grass-land degeneration are mainly environment disaster of arid continental basin. According to environment disaster geology agency, this Paper describes the origination development history process of environment disaster and its development trend, also shows that disaster geology agent caused by human productive action is mainly factor to accelerate deterioration of continenal basin large environment.Then, We predict that the environment geology disaster will daily increase, as the natural resources are explosively exploited.If the treatments of environment protection are not used, the limited greensward will be alternated by salinized land, the green grassland will be captured by desert.Therefore, the author proposed to protect policy of environment geology disaster.
