Tropical and subtropical montane regions -in which of a high diversity of climatically specialized species is threatened by climate change- is necessary to find out these climatically suitable refuges. Range shift, spices shift its range size from lowland to higher will happen in mountain area under climate change. Lapse rate plays an important role in predicting how many distance should shift. However, lapse rate was defined as a constant in different altitudinal section. Here we show that lapse rate of daily maximum temperature、minimum temperature、average temperaturesignificantly altered along elevation gradient. Difference of these lapse rate ,can be larger than 4[℃/km],is due to surface temperature、amount of water vapor condensed、solar radiation. Based on our results, spices should shift different distance in different altitudinal range in response to climate change. Given that clear lapse rate of different altitudinal range is the fundament of targeted protection, to conserve biodiversity under changing climate, our discovery can great help pinpointing the location of cold refuge.
