| 摘 要： | 在广泛收集茭蒿地理分布资料的基础上,利用Diva-Gis软件结合植被图层和海拔图层绘制茭蒿的分布图,并在此基础上分析茭蒿分布区的生境类型及茭蒿的分布与海拔高度的相互关系。收集茭蒿分布区的气象资料,利用国际上比较流行的研究植被与气候相互关系的指标和方法,包括Kira温暖指数、寒冷指数和徐文铎湿度指数,分析了茭蒿在中国的地理分布与气候的关系,讨论了茭蒿分布的上限、下限以及北界的Kira热量指标状况。

| Abstract: | According to the data on geographical distribution of Artemisia giraldii,Diva-Gis software was used to describe its distribution with land vegetation layer and altitude layer.The habitats types of distribution areas and relationships between Artemisia giraldii distribution and altitude were discussed.According to the climate data in the regions that Artemisia giraldii distributed,several indexes widely used for the study of vegetation-climate interaction were applied.These indexes included Kira’s warmth index and coldness index,Xu’s humidity index.The relationship between the distribution of Artemisia giraldii and climate in China was analyzed and the Kira’s water-temperature indexes on distribution upper limit,lower limit and north limit were discussed. |
