摘　　要：设定4个不同水分和光照梯度，测定加拿大一枝黄花的比叶质量、根生物量比、茎生物量比、叶生物量比、叶质量分数、根冠比来评估其对土壤水分、光强的响应。结果显示，土壤相对含水量60％～90％，中等光照强度（45％）最适合加拿大一枝黄花的生长。The index of leaf mass per area, root mass ratio, stem mass ratio, leaf mass ratio, leaf mass, root/crown ratio of Solidago canadensis seedlings were determined in the different conditions of water and light intensity to evaluate its response to water and light intensity. The result showed that the growth orS. canadensis was the best when the relativesoil water content was 60%-90% and the light intensity was 45%.
