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。
Based on the extensive collection of the geographical distribution data of Artemisia selengensis, the distribution map of Artemisia selengensis was drawn by using Diva-Gis software combined with the vegetation layer and the elevation layer. Based on this, the habitat types of Artemisia selengensis distribution and the distribution of Artemisia selengensis And the altitude of the interrelationship. Collect the meteorological data of the distribution area of Artemisia selengensis and take advantage of the internationally popular indicators and methods to study the relationship between vegetation and climate, including the Kira warm index, the cold index and the Xu Wen Duo humidity index, and analyze the geographical distribution and climate of Artemisia selengensis in China The relationship between the upper and lower limits of the distribution of Artemisia selengensis and the Kira caloric index in the northern boundary were discussed.
