利用DIVA-GIS软件对中国栓皮栎的地理分布及气候特征进行研究,并用该软件中的Bioclim和Domain两个模型评估未来潜在分布区对气候变暖的响应.结果表明:中国栓皮栎分布区可分为横断山脉区、云贵高原区、华北山地区、华东山丘区、辽鲁半岛区、台湾海岛区和秦岭巴山区7个亚区,跨越7个温度带、2个干湿区、17个气候区,包括8种气候类型.秦岭-大巴山-伏牛山为栓皮栎的现代多度中心.适合栓皮栎生长的年平均温度为7.5~19.8℃,年降雨量为471~1511 mm.Domain和Bioclim模型的受试者工作特征曲线下的面积(AUC值)分别为0.910、0.779,前者预测的高度适生区为秦岭、大巴山、伏牛山、桐柏山、大别山、云贵高原东部和西部、苏皖南部丘陵和华北部分山地.气候变暖趋势下栓皮栎潜在分布区可能向北回缩,面积减小.
DIVA-GIS software was used to study the geographical distribution and climatic characteristics of Quercus variabilis in China and the Bioclim and Domain models of the software were used to evaluate the response of future potential distribution to climate warming.The results showed that: It is divided into seven sub-regions of Hengduan Mountains, Yunnan-Guizhou Plateau, Huabei Mountain, Huadong Hill Region, Liao Lu Peninsula, Taiwan Island and Qinling Mountains, covering seven temperature zones, two wet and dry areas, 17 Climatic zone, including eight kinds of climate types.Qinling - Daba Mountain - Funiu MountainCumulus Quercus modern polyculture center suitable for the growth of cork oak annual average temperature of 7.5 ~ 19.8 ℃, annual rainfall of 471 ~ 1511 mm.Domain and The area under the working curve (AUC) of the Bioclim model was 0.910 and 0.779, respectively. The former predicted the high fitness area was Qinling, Daba Mountain, Funiu Mountain, Tongbai Mountain, Dabie Mountain, eastern and western Yunnan-Guizhou Plateau, Wannan hilly and part of northern China mountain.Curve climate warming under the potential distribution of Quercus variabilis may shrink northward, the area decreases.
