GIS支持的全球气候变化对中国Holdridge生命地带的可能影响研究
摘要:

该文以地理信息系统为支持手段,根据Holdridge气候-植被生命地带的分类体系,首先研究了在目前气候条件下中国Holdridge生命地带空间分布的基本格局;然后采用GFDL、GISS、OSU3个GCMs模拟的2×CO2情景下的气温和降水作为未来气候条件,揭示了2×CO2情景下中国Holdridge生命地带在空间分、面积以及海拔高度等方面的变化。

Research on Impacts of Global Climate Change to Holdridge's Life Zones of China by Geo-information System
Abstract:

Based on the classification of Holdridge's Life Zone on climate-vegetation relationship and the support of Geo-information system,the basic patterns of Holdridge's Life Zone in China under the current climate regime were studied in the first part of this paper,then the changes of spatial pattern,area and spatial distribution of Holdridge's Life Zone of China were brought forward under 2×CO2 scenarios based on simulating results of GCMs such as GFDL,GISS and OSU.It is possible that the available atea for forestry should tend to decrease in result that boreal moist forest in North China area are shrank westward,but boreal rain forest and cool temperate rain forest in Southwest China are expanded By the comparison of patterns between Holdridge's life zone and China's current vegetation,the author considers that there are some problems from naming of life zone and limiting of climatic indexes so that the patterns of Holdridge's life zone are different from one of China's vegetation Therefore,with the use of Holdridge's Model,the modification to the model will be necessary according to the real natures of the researched region In addition,it is suggested that the connections of Geo-information system and thematic models should improve the development of global change studies.
