| Abstract: | It is crucial to know the effects of climate change on the distribution of species for the conservation of biodiversity under the climate change.Many studies have lacked of using long term climate change scenarious and many climatical variables when analyzing the effects of climate change on the distribution of species,so there are high uncertainness for the effects of climate change on the distribution of species.There are about 30 000 high plants species and 600 desert plants species in China,while the ef... |
