中国木荷及木荷林的地理分布与气候的关系

Relationship between geographical distribution of Schima superba, its forest and climate in China

在广泛收集木荷（ＳｃｈｉｍａｓｕｐｅｒｂａＧａｒｄｎ．ｅｔＣｈａｍｐ．）及木荷林地理分布资料的基础上，利用目前国际上比较流行的研究植被－气候相互关系的指标和方法，包括Ｋｉｒａ的水热指标，Ｐｅｎｍａｎ的公式，Ｔｈｏｒｎｔｈｗａｉｔｅ的指标和气候分类，Ｈｏｌｄｒｉｄｇｅ的生命地带分类系统指标，以及单一气象因子年平均气温、年降水量等，分析研究了木荷及木荷林在中国的分布与气候的关系，讨论了木荷分布上限、下限以及北界的Ｋｉｒａ热量指标状况。

ased on the records of geographical distribution of Schima superba Gardn. et Champ. and its forest collected extensively, the international prevalent indices and methods of vegetation climate interaction were used and calculated. These indices include Kira′s water temperature indexes, Penman′s formula, Thornthwaite′s indexes and climatic classification, Holdridge′s life zone classification system, single meteorological factors on temperature, precipitation and so on. The relationship between geographical distribution of S. superba, its forest and climate in China has been analyzed and the Kira′s water temperature indexes on the distributional upper limit, lower limit and north limit have been discussed. The potential change of this tree species distributional area has been forecasted under future climatic changes using Holdridge′s indexes of life zone classification system and GCMs conclusions.
