Analysis of Temperature Variation Trends in Maofengshan Mt Subtropical Evergreen Broad-leaves Forest and Guangzhou City

  • Received Date: 2010-04-19
  • The responses and feedbacks of the forest climate ecosystem into the future global climate change have become very attractive issues. Analysis of historic climate data from 1952 to 2009 of Guangzhou and that from 2004 to 2009 in Maofengshan Mt forest ecosystem by using statistical method and seasonal decomposition additive model confirms that the climate in Guangzhou has recently been warming at a rate of 0.21 ℃ per decade; The results showed that the temperatures in Guangzhou and Maofengshan Mt were significantly positive correlated, the air temperature change in 2004—2009 had a decreasing trend at a rate of -0.008 ℃·a-1 and -0.293 ℃·a-1; The temperature change of Maofengshan Mt subtropical evergreen broad-leaves forest climate ecosystem positively responsed to regional climate change of Guangzhou. Occasionally, its responses appeared negative feedback before the abnormal weather, for example, before the winter-weather disaster in January and February 2008. Climate change is threatening the health of forests around the world. As temperature rises, the negative impacts of climate change are expected to far outweigh any benefits. The advanced fields need to be developed were discussed.
