This paper expects that the global change of the 21st century will be stronger than the one of the twentieth century. This is because the effects of greenhouse will be caused by increasing of draining off greenhouse gases such as CO_2,CH_4,N_2O, etc, in the globe with increase of population and development of society and economy of the world. The possible impacts of global climate change on natural disasters of Chain have been discussed in this paper and some results have been obtained. Research shows that the global climate warming gradually of the 21st century could lead to that drought in northem China may be continued to the end of this century, increasing rain fall, especiallyrain storm and rain of typhoon in southem China will be becoming the level of disaster of floods more serious; due to sea level rise in the coastal plains, the disaster of coast zone, mainly windstorm tide will be increasing and becoming strong; agricultural and forest disasters and insect pests,landslide and debris flow, soil and water loss as well as soil erosion will be augmenting; only cold and frost disasters will be decreasing to a great extent. Facing global climate change, our government and scientific circles should strength science research, participate in international cooperations positively adopt measures of decreasing and being on guard national disasters as well as adapting global climate change, in order to reduce economic loss.
