However,
the fact of climate change has difference in different regions, for
example, the warm winter increasing is significant in the regions
in North China, Northeast China, East China and Northwest China,
the extreme climate change events increasing are significant in the
Central China, South China and Southwest China (Fig. 1).
According to the surveyed results, 57.14% of the surveyed nature
reserves thought that forest maybe one of the most sensitive
ecosystems to climate change and the fragile forest types are coniferous
and deciduous broad-leaved forest. In Baimaxueshan national
nature reserve of Yunnan, they observed the distribution
line of warm coniferous forest is increased along the elevational
gradients. 35.38% of the surveyed nature reserves thought that
the climate change influenced the plant phenology, for example,
the flower time of Primula malacoides and Rhododendron are become
earlier. 87.69% of the surveyed nature reserves found that
out of its hole for the hibernating animal is ahead of time and
the migration for migration animal time in winter is pushed back.
