摘　　要：以辽西沙地15种阔叶树为试验材料,测量了其光合日变化、光响应曲线,并推算其日同化量、日蒸腾量,以及最大光合速率、表观量子效率等数值,以进行光合作用分析,结果表明:日蒸腾量较小的5个树种为刺榆、南蛇藤、叶底珠、鼠李、色木槭;阳性树种为杨树、杠柳、沙枣。Taking 15 species of broad-leaved tree species in sandy land of western Liaoning Province as experimental materials,their daily photosynthetic changes and light response curves were measured; the daily assimilation,daily evaporation,maximum photosynthetic rate,quantum efficiency and other values were calculated. Result shows that the five species with smaller daily evaporation are Hemiptelea davidii,Celastrus orbiculatus,Flueggea suffruticosa,Rhamnus davurica,Acer mono; the intolerant tree species are Populus L. Periploca sepium,Elaeagnus angustifolia.
