以福建省长乐市大鹤国有防护林场的6种相思为对象，进行叶绿素荧光参数的冬季日变化规律观测。结果显示：各相思树种黑暗中最大可变荧光强度（FV）均于午间及午后达到1 d中相对较大值；1 d内PSⅡ最大光能转换效率和PSⅡ潜在活性，肯氏相思整体要高于其余5种相思，而厚荚相思、大叶相思、马占相思相对较低。结合其林分保存率可知，肯氏相思、纹荚相思、卷荚相思在冬季较适应闽东沿海沙地生境。

This paper compared the winter diurnal variation rules of chlorophyll fluorescence parameters of 6 Acacia species in Dahe State-Owned Shelterbelts Field in Changle City of Fujian Province.The result showed that the chlorophyll fluorescence parameters Fv of all Acacia tree species from midday to afternoon achieved a relatively large value of the day ;in one day ,the maximum light conve-rtion efficiency of PSII and its potential activity of Acacia cunninghamii was higher than the rest of the 5 kinds of Acacia on the whole,however,Fv/Fm and Fv/Fo values of A.crassicarpa,A.auriculiformis and A.mangium were relatively low.Combined with the preserving rate of trees , A.cunninghamii,A.aulacocarpa and A.cincinnata were more adapt to the coastal sand in the winter.
