加拿大一枝黄花在中国的适生性研究

Analysis of Potential Distribution of Solidago canadensis in China

根据加拿大一枝黄花的生物学特性,筛选了平均最高气温、平均气温、平均最低气温、降雨量、降雨日数及日平均日照等6个气候参数,应用欧氏距离的数学模型,评判了加拿大一枝黄花适生区上海与中国其它17个气候大区相应地点的30年（1961～1990年）的气候相似程度。采用农业气候相似等级标准法,划分了加拿大一枝黄花在我国的适生区、次适生区和非适生区,绘出了加拿大一枝黄花在中国的适生分布图。

Based on the biological characteristics of Solidago canadensis, the average maximum temperature： average temperate, average minimum temperature, rainfall, data of rainfall and sunshine length were selected as the climate factors which affected the distribution of Solidago canadensis. Euclidean distance was used to evaluate the similarity of climate factors for 30 years （1961 -1990） between Shanghai where was the potential distribution area of S. canadensis, and other 17 climate districts in China. The potential distribution, less suitable distribution and unfit distribution of S. canadensis in China were concluded by agricultural climate similar criteria, and the potential distribution map of Solidago canadensis in China was drawn.
